Hello and welcome to my first instructable!
Today I will be showing you how to make a RGB LED color mixer.
Step 1: Parts Needed
For this instructable you will need:
Seven Pushbutton switches
One Red LED
One Green LED
One Blue LED
One CR2032 Battery holder
One CR2032 Battery
Step 2: The Schematic
The schematic is really simple.
1: For the first three switches you just normally connect the LEDs.
2: On the second row you must use 2 diodes on each swich,just use them like normal wire but be sure to have the outbut of the diode going to the LED
3: The last button will control all three LEDs, repeat step two but add three diodes to all three LEDs instead of two.
Simple but AWSOME!!!
Step 3: The Result
This project is really handy.
It is perfect for teaching children about which colors can be mixed to create new colors.
It is possible to put a big blob of hot glue on the top to mix the colors but i like it how it is.
Good luck to anyone who is building this!
