i think i have differnet temperature sensor

Hi there! you would have to add an if/else statement with temperature ranges that would turn on or off the LEDs you add! Hopefully, that helps!

Hi there! Unfortunately, we don't have a code already made in ARM assembly code. Sorry!

Hi Jo! We used six inches of elastic for the scrunchies we made, but you can use whatever length you feel is best for you!

Hey Andre! After a quick search, it seems like the updated IDE is having trouble converting the symbol correctly. Try looking at the thread found below at the 2020 responses to the question! They should have an IDE version closer to yours and may have more chance of working! forum.arduino.cc/t/solved-how-to-print-the-degree-symbol-extended-ascii/438685/42

Hi Furry Knight! We're glad the video helped you!

Hi Alex! I'm sorry you're having that problem! Are you using TinkerCAD or did you make it in person? If it was on TinkerCAD, could you reply with the link? IN PERSON: If you made it in person and the code is compiling correctly and you followed the code from the video, there may be an error within your circuit wiring. I would try looking at your wiring in comparison to the original schematic (in the description box). If the wiring matches perfectly, the components may not be working properly. For an LED, I would use a resistor that is approximately 300 Ohms. For the grounding resistor, I believe you may need about 220-Ohm resistors, but you can use higher resistances to ground the pushbutton. An easy way to check if the components are the ones not working is by making a simple series circuit where you put the LED, a resistor, and a pushbutton connected to the power source within the Arduino Board. Below I linked an example of how to test your circuit: www.tinkercad.com/things/kJpmFD9xRgd-mighty-bigery/editel?sharecode=XjwjhFaxDQMreg_53MRyBF0yF-AhfUfQnA-jjseGCf4 Another common error when making the circuit in-person is that an LED can only be connected one way. The longer leg of an LED (the anode) should go to the numbered pins in the Arduino. The shorter leg of an LED (the cathode) should go to one of the GND pins. You can put a resistor either between the long leg and the numbered pin, or between the short leg and the GND pin. However, that would not explain the buttons not working, that may be a problem with the resistance that you use to ground them or something in the code being off. Look at the original TinkerCAD code in the description box and maybe compare line by line when you're looking at the for loop that controls the LEDs and the buttons. TINKERCAD: If you used TinkerCAD and you followed the tutorial, did you make it on a personal file or did you copy and tinker the original circuit found in the description box? I re-check the code that is linked to see if there's a mistake on our side and it seems to be working fine! If you use the link in the description box, it should work! If you did not use the link, I would try once again looking at the wiring, that's the most common error. If that seems to be correct, maybe re-check your code in sections. Specifically, the beginning of the for loop that controls what LEDs are randomly turned on. Try looking at the code linked in the description box, it should be very detailed with a lot of comments. Hopefully, this is helpful!

Hi Ahmad. The system's default is Celsius. If you forward to time 14:45, you can see we edit the code to convert to Fahrenheit from Celsius. If you are using the code line by line, deleting line 28 should do the trick. Thanks for the question!

Glad it helped!

I have no idea 😂

Hello Pieter! If you would like to add more buttons and LEDs to the program only using the digital pins (which are the top pins on the diagram), you would just add your LEDs and respective buttons to the remaining free pins. There is a loop that randomizes the LEDs that turn on, so do try to put all the LED pins together to make it easier to randomize. For example, put all your LEDs on pins 0-6 (which gives you 7 LEDs) and all your buttons from pins 7-13 (which gives you 7 buttons). Your loop that randomizes the LEDs (in line 35 of the original code) would therefore have to be from 0 to 7 (this would only randomize numbers up to 6). In total, you should be able to get 7 LEDs and 7 buttons on that way. If you want more than 7 LEDs and 7 buttons with one Arduino, you would have to use the analog pins (which are labeled "A0, A1, A2, ..." on the Arduino). I believe you can use the analog pins as digital using the same digitalRead and digitalWrite commands. However, you would have to call each pin "A#" instead of just # since the singular numbers are already used for the digital pins. This would mean you'd have to alter your codes to adapt to the fact that the pins are no longer only integers. So whenever you are declaring the "const int _______" variables, you won't be able to do that with the analog pins since it will give you an error for having an "A". Therefore, you would have to hard code the digitalRead/digitalWrite/pinMode commands for any LEDs and buttons wired at the analog pins. You may also come into a problem whenever you are randomizing which LED turns on (once again, line 35 in the original code that is linked) if you have LEDs on the analog side since it will no longer be a pin that is a number only, so you can't randomize inside of the digitalWrite. You would have to still randomize a number from 0 to 10 (if you wanted 10 LEDs and 10 buttons), but maybe use an if-else statement to label each pin with a number from 0-9 as needed. If you need any more information or clarification, leave a comment and we'll answer as soon as we can!

@@digatsmu6667 I tried making a program but i doesn't work. I have an Arduino Mega so I have like 50 pins. I want to make this program with 10 leds and 10 buttons but I can't. I hope you guys can help me.
