How do you do it with all the leds on and when you put your hands closer to the leds they turn off one by one?

[@Waiduino]

Hi so basically you would need to modify the code. I will do that for you right now if you would like. You just have to set the status to each LEF as on and then every second it detects a hand, it will turn off an LED by turning it off. Let me comment the code now

[@mvsaikartheek633]

hello how to give connections for led positive and negative and resistor?

You can find that all in the circuit diagram. The GND should connect to the railing which is connected to a resistor which connects to the negative side of the LED and the positive side connects to a pin on the Arduino designated in your code. You can find a walkthrough in my first ever video. Hope this helped!

how many ohms resistor did you use

[@Waiduino]

Hi! It should be 330 ohms, I’m not entirely sure. The lower resistance, the brighter your LED is gonna be. Hope this helps!

[@Ajetnahom]

What is the resister number you used bro?

[@Waiduino]

I believed I used like 500 or 1k but feel free to use whatever you want. Lower resistance means brighter color so I normally like LEDS to shine more

[@zeeshamt1695]

Can u tell me the number of the risistor and the wites

I used a 1k ohm resistor. The higher resistance, the less bright your LED will be. What is your question about the wires?
