Arduino Project 010 - Serial Controlled Mood Lamp

RonWang1年前 (2024-07-23)电子编程497

For Project 10, you will revisit the circuit from Project 8 — RGB Mood Lamp, but you’ll now delve into the world of serial communications. You’ll control your lamp by sending commands from the PC to the Arduino using the Serial Monitor in the Arduino IDE. Serial communication is the process of sending data one bit at a time across a communication link. 

This project also introduces how to manipulate text strings. So, set up the hardware as you did in Project 8 and enter the new code.
