In this page, you will find a brief introduction to Arduino and NodeMCU micro-controllers typically found in Atal Tinkering Labs. You will also find circuit diagrams code-snippets for integrating Sensors & Actuators with Arduino and NodeMCU boards. You can use the information in the below slide decks as a reference to integrate a variety of sensors and actuators on the Tinker Blocks.
Basic understanding and working knowledge of sensors, actuators is desirable to work on Arduino and NodeMCU boards (though not a must).
