In the schematic above, a pulse applied to the base of the transistor allows current to flow from the +5v source to the relay coil, thus toggling the. Therefore, we can connect led directly to arduino's pin. This relay has 5 pins.
Sir, can you please help me in finding out which relay board i need to use for controlling high ampere rating devices such.
14+ Arduino Relay Board Schematic. Relays are suitable for driving high power electronic devices such as lights, electric fans and air condition. Use cheap < $15 arduino 16 relay boards. Shown below is the connection details to connect 4 channel relay board given below is a sample code to operate the 4 channel relay board using arduino. Easy to use relay control commands.
