Arduino Project 026 - Dual Servo Control

RonWang1年前 (2024-11-14)电子编程748

This project you’ll create another simple project, but this time you’ll control two servos using commands from the serial monitor. You learned about serial control in Project 10 when you were changing the colors on an RGB lamp with serial commands. So let’s cannibalize the code from Project 10 to make this one.

Project 26  Dual Servo Control
