Open circuito.io and let's start!

Add components:

• Arduino Uno R3 board
• 2x Servo motors
• TCS230 Colors sensor

After adding servo motors app automatically added voltage regulator (5V), ceramic capacitor(100nF) and electrolytic capacitor (1mF/50V).

Connection:

Now pay attention to where the servo motors and sensor are connected.

• Digital pin 2 - First servo motor
• Digital pin 3 - Second servo motor
• Digital pin 4 - TCS230 Out pin
• Digital pin 5 - TCS230 S0 pin
• Digital pin 6 - TCS230 S1 pin
• Digital pin 7 - TCS230 S2 pin
• Digital pin 8 - TCS230 S3 pin
  

Now let's write the code!
