Wi-Fi Macro Board / Macro Pad / Macro Keyboard

This project constructs a DIY macro board which has a clickable knob and 9 keys. The wireless device executes macros on a computer over Wi-Fi.

Note: This is a proof of concept project. The response time over Wi-Fi is not as good as Bluetooth or ESP-NOW based macropads. I recommend you to implement ESP-NOW based OnkarRuikar/esp-now-macropad instead.

Features

Following features are implemented out of the box:

• a clickable knob to control system's master volume. Knob click handles audio mute and un-mute.
• 9 touch keys
  • 4 keys to control media
    • play / pause
    • previous media
    • next media
    • mic mute
  • turn off monitor
  • 4 remaining keys could be configured to add more macros

Existing macro boards available in market are either wired (USB) or wireless (Bluetooth) HID devices. This wireless macro board uses Wi-Fi to communicate with PC.
