The techniques shown should work across all Raspberry Pi versions!

Glad it Worked, Umer!

The L298N driver should work with a DC Motor

Glad you found the tutorial helpful! It does sound like a wiring issue. Double-check the connections to the motor driver and ensure the sequence matches the code. Small wiring mistakes can cause the motor to reverse.

Will keep this in mind for future videos

Sure! Try running your script with sudo to give it the necessary permissions: sudo python your_script.py If that doesn't work, add your user to the gpio group: sudo usermod -a -G gpio your_username Then log out and log back in. This should fix the permission error.

@raspberrypimadeeasy oh nvm i got it fixed thanks anyway

Sorry to hear you're having trouble! Make sure the resistor value you're using is appropriate for the LED. Double-check all your connections and try running the script with sudo. If the issue persists, you might want to check the GPIO permissions with sudo usermod -a -G gpio your_username and then reboot.

Hi ! For longer distances between the driver and motor, you might experience signal degradation. Using shielded cables can help reduce interference. If the distance is significant, consider using a motor driver that supports long cable runs or adding repeaters. Ensuring proper power supply is also crucial. Hope this helps!

That's a great question! I'll probably make a video on that topic soon.

Thanks for reaching out! It sounds like the Raspberry Pi 5 might be experiencing some power or resource-related issues when running the servo for an extended period. Here are a few things you could try to troubleshoot: Power Supply: Ensure that your Pi 5 is getting enough power, especially if you're running multiple peripherals. Servos can draw significant current, which might cause the Pi to crash if the power supply isn't sufficient. Overheating: Check if your Pi is overheating. The Pi 5 has a higher performance than its predecessors, so it may generate more heat, particularly when running tasks like controlling a servo. You might want to check the temperature or use a heatsink/fan. Servo Power: If you're powering the servo directly from the Pi, it could be causing a power drop. It's recommended to use an external power supply for the servo to avoid overloading the Pi's power circuit. Code Optimization: Review the code controlling the servo to ensure there are no memory leaks or resource-intensive operations that might cause the crash after some time. Try these steps, and let me know how it goes.

@@raspberrypimadeeasy Hi, I'm using the active cooler with the Pi 5. I'm not sure how to monitor temperature better. As for the Servo power, I tried powering the servo externally at current 5v==1.8A, but this caused the Pi to crash immediately. I think I changed the library or something and it seems to be working for now. I'm not entirely sure, but it is fine for now, and I don't know what I did! 😅 Thanks for the vids though, hope you'll make more! Do you have one maybe from people used to Arduino looking to use a Pi? I would definitely watch

@@brightfuturelearningacadem1042 Glad it worked, looking forward to making more videos. Your support is appreciated

If your 16x2 LCD screen only requires four connections (ground, 5V, GPIO 2, and GPIO 3), you can adjust the code to match these pin requirements. Code Adjustments Change the GPIO Pins: Update the pin definitions to match the GPIO pins you are using. Use I2C Communication: Since you're only using two GPIO pins for data, it's likely your LCD uses an I2C backpack. You can utilize the smbus library or the gpiozero library with I2C support. Here's an example code snippet to get you started: python Copy code from gpiozero import LED from time import sleep from luma.lcd import CharLCD # Define the pins for I2C lcd = CharLCD(pin_rs=2, pin_e=3) lcd.clear() lcd.message("Hello, World!") Explanation pin_rs=2 and pin_e=3: This indicates which GPIO pins are used for RS and E (Enable) signals. Using I2C: If your display uses an I2C interface, you'll need to install the relevant library (luma.lcd in this case) that simplifies the code and makes it compatible with fewer connections. If the display requires a specific library (like Adafruit_CharLCD for standard connections), check the documentation for details on using fewer pins. Final Note Make sure to confirm the wiring based on the type of LCD you're using. If it's an I2C LCD, you should also ensure you have the correct library installed and configured on your Raspberry Pi.

@@raspberrypimadeeasy i made sure the binary is correct and i also installed luma.lcd, but the code still doesnt work and it says Traceback (most recent call last): File "/home/pie/Desktop/screen.py", line 3, in <module> from luma.lcd import CharLCD ModuleNotFoundError: No module named 'luma' Sorry for asking for help again but i am seriouslly lost at how i could fix this.

@@Poylo It looks like you're encountering a couple of issues. Let's tackle them one by one. 1. ModuleNotFoundError: No module named 'luma'** This error indicates that the `luma.lcd` module isn't installed correctly. You can try reinstalling it using pip: pip install luma.lcd Make sure you're using the correct Python environment where your script is running. 2. Using a 16x2 LCD with I2C Module For your 16x2 LCD screen that uses only 4 wires (ground, 5V, GPIO 2, GPIO 3), it sounds like you're using an I2C module. This simplifies the connection and reduces the number of GPIO pins needed. Here's how you can modify your code to use the I2C interface with the `luma.lcd` library: 1. **Install the required libraries**: pip install luma.lcd smbus2 2. Modify your code: Replace your existing code with the following: from luma.core.interface.serial import i2c from luma.lcd.device import hd44780 from time import sleep # Initialize I2C interface serial = i2c(port=1, address=0x27) # Adjust the address if necessary device = hd44780(serial) # Define LCD parameters LCD_WIDTH = 16 # Maximum characters per line def lcd_string(message, line): """Send string to display.""" message = message.ljust(LCD_WIDTH, " ") device.text = message device.show() # Main program loop if __name__ == '__main__': while True: lcd_string("Raspberry Pi 5", 1) lcd_string("16x2 LCD Display", 2) sleep(3) ``` This code uses the `luma.lcd` library to interface with the LCD via I2C. Make sure to adjust the I2C address (`0x27` in this example) if your module uses a different address. Additional Tips - Check Connections**: Ensure that your I2C connections are correct (SDA to GPIO 2, SCL to GPIO 3). - I2C Address**: If you're unsure about the I2C address, you can use `i2cdetect` to find it: sudo apt-get install -y i2c-tools sudo i2cdetect -y 1 ``` This should help you get your LCD working with the I2C interface.

Glad it worked

Great suggestion!

No worries!

Hi! The error you're encountering typically happens when the system can't detect the correct hardware base address for the GPIO pins. This can be resolved by ensuring that your Raspberry Pi is fully updated. You can try running the following commands: ``` sudo apt-get update sudo apt-get upgrade ``` Also, make sure the `gpiozero` library is installed and configured properly. If the issue persists, consider switching to the `RPi.GPIO` library to see if that helps. Hope this helps!

To address the jittering issue with your servo, try adjusting the min_pulse_width and max_pulse_width values, as different servos may require slight tweaks in those values to operate smoothly. Some servos are more sensitive to pulse width variations, and using values that are too low or high can cause jittering. Additionally, you could try adding a small delay (like `sleep(0.05)`) between angle changes to prevent rapid movement, which sometimes helps reduce jitter.

My understanding is that you had to change the line chip = gpiod.Chip('gpiochip4') to chip = gpiod.Chip('gpiochip0') because the GPIO chip on your system is identified as gpiochip0 instead of gpiochip4. This can vary depending on the hardware and configuration. Thanks for pointing that out

you are a solved this problem?

@@g-4660-i4l no solved

Try the following: 1. Use a stabilizing delay: Add a short delay after the movement, allowing the servo to stabilize. For example, `sleep(2)` after setting the angle might help reduce shake. 2. Adjust the pulse width: As with jittering, adjusting the `min_pulse_width` and `max_pulse_width` to fine-tune the signal to match the servo’s specifications could reduce shaking. 3. Check for power supply issues: Make sure your power supply is consistent and sufficient to drive the servo motor without fluctuations.

Sounds good!

@FHCRT2 can you provide more details on what's not working ?

@@raspberrypimadeeasy It does not work

@@FHCRT2 if you require more help please provide more detail on what's not working. I won't be able to help you if I don't know what's not working

@@raspberrypimadeeasy I used the whole code you wrote and it is not working. Also I have a raspberry pi 4 not arduino Uno. And I have a breadboard connected with a transfer of all GPIO pins to the breadboard.

Thank you for your feedback!

seems fine to me? maybe wait for HD?

Yes, there are radar sensors that can be used with a Raspberry Pi to calculate speed and velocity. Here are a couple of examples: • OmniPreSense OPS243-A Doppler Radar Sensor: This sensor was used in a project to build a “speed trap” that uses machine learning to identify vehicles and a radar sensor to measure speed1. The data was then reported to the cloud1. • HB100 Radar Sensor: This sensor can be wired to a Raspberry Pi to calculate the speed/velocity of an object2. • A111 Pulsed Radar Sensor: This is a single-chip solution for pulsed coherent radar (PCR) and comes complete with antennae and an SPI interface capable of speeds of up to 50MHz3. Applications for PCR include distance-sensing, gesture, motion, and speed detection.

@@raspberrypimadeeasy I just want to know if there's sensor's do the same thing, that i can use in proteus simulation

You can simulate the ultrasonic sensor in Proteus using the Ultrasonic Sensor Library

Hey @BradenNeighbor, Give this link a Read mesquite-bead-b16.notion.site/Read-Me-c99015f8dd4f48c6861445a952b40d56 If it still doesn't work Here are a few things you could check: Wiring: Please ensure that the wiring of the ultrasonic sensor to the Raspberry Pi is correct. The TRIG and ECHO pins should be connected to the correct GPIO pins on the Raspberry Pi. Sensor Functionality: Check if the ultrasonic sensor is working correctly. You can do this by testing the sensor on a different circuit or using a multimeter to check if it’s sending and receiving signals. Run in Terminal: You mentioned you didn’t use the CMD part at the end. It’s possible that the script might not run correctly if it’s not executed in a terminal. Try running the script directly from the terminal using the command python3 [script_name].py, replacing [script_name] with the name of your Python script. Permissions: Ensure the script has the necessary permissions to access the GPIO pins. You might need to run the script with sudo to give it these permissions. Python Version: Check if you are using the correct version of Python. This script should be run with Python 3. lgpio Library: Ensure that the lgpio library is correctly installed and working. You can test this by running a simple script that turns an LED on and off. Remember, it’s always important to troubleshoot step by step, checking the most likely issues first. I hope this helps! Let me know if you have any other questions.

Hello mate i did all the steps but gaved me the message "in <module> import lgpio as GPIO" and is there anyway to do something? (And also is saying "No module named 'lgpio' ")

It seems you’re encountering an issue with the ultrasonic sensor code on your Raspberry Pi 5. Import Error for ‘lgpio’: The error message “No module named ‘lgpio’” indicates that the lgpio module is missing. To resolve this, you can try using the gpiod library instead of RPi.GPIO. The Pi 5 uses gpiod for GPIO access. Install the lgpio package by running: pip install lgpio Update your code to use gpiod: Python import lgpio
