If you see the code listing for the servo mechanism, you will see that the key to controlling the speed is basically the duration of the delay (variable pulseWidth) between sending a HIGH and LOW ...

His code listens for serial commands and manipulates the motors accordingly. He wrote a Python script using pyserial which talks to the Arduino.

Serial Servo HATs and Raspberry Pi, Arduino expansion boards 3:15 pm October 2, 2023 By Julian Horsey While building robotics projects, the importance of controllers and motors cannot be overstated.

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...
