Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations. You'll see something like this: ...

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 ...

Here we have provided PCB layout, circuit diagram, and Gerber files so that you can build or directly order this Relay Driver Module. Previously we have built 4-channel Relay Driver Module, but this ...

Simply, it’s an Arduino library for communicating with Modbus slaves over RS232/485 via RTU (remote terminal unit) protocol. In conclusion, the Modbus 2-channel 5V relay module is a very useful device ...

Smartphone-Controlled Arduino Projects: Use Bluetooth and Wi-Fi for Wireless Communication These two practical Arduino projects show you how to control a relay from a smartphone using an Arduino Uno ...

Patrick Thomas Mitchell has been once again been creating awesome Arduino speech recognition and relay board modules which have launched over on the Kickstarter website ...

Arduino Uno is powered with a 12V DC adaptor/power source. The relay module and Bluetooth module can be, in turn, powered using a board power supply of Arduino Uno. Author’s prototype is shown in Fig.

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.

From the circuit diagram of the module, it is clear that, apart from the module only a few external components are needed to build a relay-driver circuit. Yes, there is a chance to realize one simple ...
