Arduino plugin

pymodaq_plugins_arduino groups a set of instruments built around an Arduino or ESP32 board. Most instruments use the Telemetrix library to drive an Arduino over USB; the ESP32 instruments use Telemetrix-AIO to talk to the board over WiFi. No firmware change is needed to change the behaviour — a fixed sketch is flashed once, and everything is then driven from Python.

In the DAP project, the plugin is used on a thermal test bench built around an Arduino Nano ESP32: a fan and a heater are driven in PWM and the temperature is read from a PT100 probe, for the physics lab sessions (TP) of the BTS CIEL at Lycée Édouard Branly.
