Hi, I have a question, the biometric reader you are using would be the dy50 ?

Codes sources pleas

cool

Thank you for this I needed this so much as other channels wanted to use a library but i needed to alter the code to allow and io expander and use a proper debounce. Now I can code it without code. Well explained Sir…🎉

Nice! I'm originally from almost where you are located (always good to see familiar names on the map). As for the altitude: this should be corrected for QNH (so, like you're saying, the weather basically). I've seen tables for that in other sensor manuals; still gotta check this one.

Perfect illustration 👍

Can you hook 4 of these to a nano?

Are you agent Smith... sounds to me like: "Mister Anderson... you disappoint me..." 😀 Now back to the topic: where you able to *write* a card / fob with this device?

Quick question: on which side should we solder? On the side with the writing or the side with the components? I did the soldering on th side with the writing and I feel like this is why it didn't work. Looks like the copper wiring is on the other side and if the soldering was superficial it didn't make a proper connection.

thank You Bro so much! for the usefull video

this very easy to understands

And how to check wiring and colors how is connected inside???

Can i add 2 turbidity sensor with ads1115? I don't have A0 space anymore

ON my project, i have also an lcd i2c display. When i power supply the project from a external source, not from usb cable for arduino, the lcd display doesn't show any data. Just powers on the screen. Do you have any idea what could be the issue?

spettacolare, volevo chiedere, si può controllare una ventola a 24v con lo stesso sistema???

How can I found the adress for the sensor??

just a small issue, please do not use f word at 4:00, I was watching this video with my son

have you completed the writing code?

hi thx for best video.. can you help me? how to writing code? not found on bucket list.

Thx, could you please explain how to use third wire(yellow =hall sensor out put ) for feedback control

is it pwm controller or voltage reducing?

Since this board can be soldered on both sides, you could've soldered the headers the other way around so that you can see the markings.

Thank you for the demonstration. I will go buy one.

Great ! I could relate the concept of the video to PWM chopper signal.

Schreckliches Video 👎👎👎

for how long should we iterate through the output pins and provide voltage in order to detect which column key is pressed? should this procedure of reading the column go on forever until the key is pressed?

thanks! it's working.

Thank you. This is the most simple explanation i have watched

hlw i want to contact to you please send me your contact info

What are these plastic boxes called?

My BMP280 came without the onboard level shifters. Meaning it runs on 3V3. I have a couple of options... 1) Provide two rails - 5 volts and 3.3 volts - and Include separate level shifters. 2) Is more interesting... Run the Arduino and the display on 3V3, too. Here's how to do it. The Arduino has an auxiliary 5V output pin. This output is after the Arduino's voltage regulator. Simply input (yes, input) 3V3 on this pin and the Arduino will run, happily. Next, use a 3V3 1602 Display. Or, convert a 5V unit. They (mostly) all use a common board which can be configured as either voltage. The 3V3 model uses a L7660 negative (yes, negative) charge pump to lower the 3V3 ground point to a net 5 volts = clever. All the needed vacant pads are already on most 5V PCBs. Just add the L7660 and a couple of caps. HTH.

Thx, cool

I know it is an old video, but I still hope you can see my message and help me with my question, I am working on a project of a chess board, the plan was to attach a rfid tag to each piece and read it from the board. the complex part is that we need 64 readers (or antennas) to read the tags from each square (so we can tell what piece in this square). is there any way to accomplish this task? by the way each square is 4x4cm. and I am looking for most effective and cost efficient way. thank you in advance

So , it detects only humans movement? Can it detect a car if it-s moving?

when i was at college, i tied to understand it many times, but failed every single time and now i am got it in first attempt, Thanks sir

To wire up I2C, you need to use pull-up resistors. It's part of the specification. Great video I must say.

Muchas gracias por realizar este video, muy claro e instructivo. Por fin pude programar mi BMP 280, pensé que estaba roto. Saludos desde la ciudad de Córdoba, Argentina.

well done

Here is what I did with one of those.... kzbin.info/www/bejne/eqW6eoyIndejidU

thank you so much from India

is 300 and 1000 speed of RPM?

Does toeprints work?

So the sensor is just completely inaccurate when it comes to the altitude?

Can you also base the detection on code? Instead of adding resistors? And then calculate the distance to the object it sees?

Hi pal, nice sharing. Wondering if any custom PCBs are required for any upcoming project? Would love to sponsor and reach any collabs with you! (PCBWay zoey)

"You don't know how it works? Well, I didn''t know it either so I had to look it up" this is the type of tutorial I like

Very Helpful thank you so much!

Thank God you explain so good , you are a life saver, a subscriber from now on
