The Arduino-controlled relay circuit is shown below. This circuit explains to you how to control a relay with the help of an Arduino. The required components to build this circuit mainly include the Arduino Board, Resistors – 1K & 10K,BC547 transistor, 6V/12V relay, 1N4007 diode & a 12V...
Arduino Pin Turns On Transistor>>Transistor Turns On Relay>>Relay Connects Appliance To 120V Power Outlet. With that out of the way, you should also use a resistor to connect your Arduino to the transistor. This prevents the transistor from drawing excessive amounts of current and burning it ...

By just using the function bool...
Learn how to connect 4-channel relay module to Arduino, how to program Arduino to control 4-channel relay module step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly ge
I have 4 of the ZS-040 adapters. I am trying to learn the code but every time I try to connect to the bluetooth it just says connection rejected. When I put in the AT commands I get nothing back. Any Ideas? I’m looking to do some master to multiple slaves to multipule slaves....
