OPERATIONS

• If skip wants to send sweep hard command to Right sweeper: holding down the Right button
• If skip wants to send sweep soft command to Right sweeper: press the Right button
• If skip wants to send sweep hard command to Left sweeper: holding down the Left button
• If skip wants to send sweep soft command to Left sweeper: press the Left button
• If skip wants to send stop command: press the Stop button to broadcast stop command to both sweepers

In other words:

• Stop: press the stop button
• Hard sweep: holding down on a button
• Soft sweep: press a button

DEVICES

• ESP-A: Skip device
• ESP-B: Right sweep device
• ESP-C: Left sweep device

NOTES

• Getting started with ESP32:
  • Board module: NodeMCU-32s
  • Everytime uploading to board, hold IO0 button until connection established
• For easy understanding and coding, use the same pins for IO accordingly on both boards.
• GNDs on each board should not be tied together. GND for different devices are different.
• Each device on each board should have different GND
• 4-leg LED can have different wiring diagrams: common anode, or common cathode. The ones I have is common cathode.
• Since my wiring is common cathode, my program is sending LOW to turn LED ON, and sending HIGH to turn LED OFF
