SIM900-Arduino-Relay-Control This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL.

Here we are making a simple project with Arduino which uses three basic components that are IR Sensor, Relay Module and DC Motor. Here we will interface IR sensor with Arduino to control DC Motor.

A sound sensor module and a soil moisture sensor are also part of the kit, enhancing its capability for various applications. The kit features a 1-channel relay board without an optocoupler, operating ...

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...
