Continuous Servo Motor
Introduction
A continuous servo motor looks like a regular servo motor, but instead of turning to a specific angle, it spins continuously in either direction. You can change the speed and direction using values between 0 and 180.
• 90: stop
• < 90: spin one direction
• > 90: spin the other direction
At 0 and 180 are the max speeds for either direction. The closer you get to 90, the slower the servo turns. This makes continuous servos great for wheels, fans, or spinning mechanisms in interactive projects.
Circuit Assembly
Connect the servo to any pin. In our example, we're using D10/D11. The pin that you connect your servo to corresponds to a pin value on your code. We're using D10/D11, which corresponds to 11. You can remix yours to look like this:
• D11/D10 → servo_pin = 11;
• D9/D8 → servo_pin = 9;
• D7/D6 → servo_pin = 7;
• D5/D4 → servo_pin = 5;
• D3/D2 → servo_pin = 3;
• D1/D0 → servo_pin = 1;
Servos use a lot of power, so make sure you have an external power supply plugged into the micro controller.
