This isn’t an ESP8266 shield, either: you can write code for the ESP module, connect the serial pins, and hit the program button. The basic functions of the Arduino IDE – pinMode, digitalRead ...

There is no reason to use an ESP8266 AND an arduino. The cpu on the ESP8266 is a 32 bit risc running at 80 Mhz, the arduino is an 8 bit AVR running at something less, maybe 32 Mhz.

The OONTZ uses a 3D printed case, a 16 button keypad, an Arduino Leonardo, a monochrome driver, and a few potentiometers. It's actually a pretty simple thing to build yourself provided you can the ...
