# About The Project
AButton V3 is a WiFi connected push button based on EspressIF's ESP32-PICO-D4. The push button "boots up" AButton and send message to MQTT broker. It will go to sleep after work be done.
Additionally, the board includes a WS2812B RGB LED and buttons to aid in your development.

# How To Programming Your Own Firmware
# Use ESP Flasher To Program AButton
We designed pins 2 x 4 for match ESP Flasher. ESP Flasher is an USB to UART converter. It's best tool to program AButton. See the photo for how to wire it
# Installing via Arduino IDE Boards Manager
Espressif has added support for the Arduino Boards Manager and by installing this way, you get the benefit of a slew of great built-in examples. Instructions for installing via the board manager can be found at espressif's arduino-esp32 GitHub (opens new window).
If you have successfully installed the ESP32 core to your Arduino IDE, you should see the following under Tools with the ESP32 Pico Kit selected:
