Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

Simply push a button to scan the colour of the object and you’re given the RGB colour values as well as an indication of the measured colour on an RGB LED.” ...

BLUE4 to a 100 ohm resistor to pot pin 17 To ground the LED busses, we’ll be using four 2N2222 transistors. The Arduino will trigger each transistor individually through a 1Kohm resistor.

Now, though, it shouldn’t be hard to control the RGB LED strips through an Arduino, a computer, or even an Android/iOS device with a small IR LED plugged into the headphone jack.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...
