Firmata is a protocol that is used to communicate with microcontrollers from any tablet/pc over the serial interface. There are implementations of this for other platforms too along with Arduino. You can find support for this if you are using any Arduino IDE released after 2008.Use of this protocol lets you access GPIO of Arduino from any host device natively without uploading the sketch each time you change the sketch. You can use Arduino as ADC for your Pi as it doesn’t have native ADC pins, you can also interface…
