TTY Power Management for DC 5V 1 Channel Time Delay Relay CH340 CH340G Smart Programmable USB Time Control Switch Board USB To TTL Module for Arduino PC - Mephistophiles/tty_relay ...

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.

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

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 ...
