Envistia Mall offers a full range of Arduino-compatible microcontrollers and shields compatible with the popular Arduino Uno, MEGA2560, Nano and Pro-Micro models. Arduino is an open-source electronics platform based on easy-to-use hardware and software. These microcontroller boards are able to read inputs from various sensors and detectors such as motion detectors, light sensors, the press of a button - and turn them into outputs - activating a motor, turning on an LED, or posting something online. You can tell your Arduino board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language and the Arduino Software (IDE).
