I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...
IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...
Normal: Manual control of each relay All ON: Activate all relays All OFF: Deactivate all relays Alternating: Alternate between odd and even relays Sequential: Activate one relay at a time in sequence ...
Arduino boards are great to get started with electronics has they offer an ecosystem of expansion modules and libraries, as well as tutorials, that may it easy to get started with almost any projects.
O. What is RelayModule Library? If I use it, how easier life will be ? If you have made some Arduino project with Relay Modules, you probably wrote some scattered code for relays. Scattered Code ...
Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...
