Working and Demonstration: For demonstrating the working of this Relay Module, we have used an Arduino Uno board for controlling relays. All four relays are connected with Arduino at 8,9,10 and 11th ...

In this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

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 ...

you can download from Arduino Library Manager or directlly download from this repository. Connect the 8-channel Solid state relay v1.0 to Arduino board's I2C port, compile and upload ...

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

Power on the receiver circuit next and wait for five seconds as defined in receiver code. Press pushbutton (S1 or S2) in transmitter circuit to control the corresponding relay in receiver circuit.

RS Components (RS) has introduced easyE4, a new range of logic control modules from Eaton. easyE4 offers a selection of controller base units and I/O expansion modules that speed up and simplify the ...
