Gravity: Transparent Case Relay Module

1. Example Code for Arduino-Button Control Relay

This guide offers a comprehensive walkthrough for setting up and programming an Arduino to control a relay via digital push buttons, enabling the operation of a submersible pump. It covers necessary hardware, detailed wiring diagrams, and provides sample code for seamless integration.

2. Example Code for micro:bit-Onboard Button Control Relay

This article provides a comprehensive guide to controlling a relay using the onboard buttons of a micro:bit. It includes hardware preparation, wiring diagrams, and sample code compatible with both MakeCode and Mind+. The guide demonstrates how to configure the micro:bit to switch the relay state, enabling or disabling a connected pump. Beginner-friendly, it is perfect for hobbyists and educators looking to create interactive projects with micro:bit and relay modules.
