DIY Arduino Color Sensor

How to make a DIY Arduino Color Sensor

4 Leds (Green,Blue,Red,Yellow)

4 220ohm resistor

1 LDR

1 10k resistor

Female Pins

PCB

Shape your design to the PCB. Then cut it. I used 3.5cm by 2.5cm

Start Soldering the Leds like the schematic.

Solder the LDR with the 10k resistor and the Pins like the schematic.

Connect the Pins like the Schematic and Upload the Code.

After you have Upload the code, see how your DIY sensor finds the colours.If a colour matches,the led colour will flash 3 times.Hope you enjoy!!
