Simple 5v Relay Circuit

The working of the project is based on the functioning of the relay and the ability of arduino to control the relay.

Simple 5v relay circuit.

Thus only 9 vdc passes through the handheld pushbutton. The only link is by the magnetic field. Also check our 1 minute timer circuit using 555. The relay in the circuit has a coil rated for 9 vdc and a switch rating of 10 a at 117 vac.

If the person holding the switch decides to take it apart. Circuit diagram construction. Connect all on your proto board as shown in the diagram. Below is the circuit diagram for simple delay circuit using 555 ic.

The driven relay can then operate as a switch in the circuit which can open or close according to the needs of the circuit and its operation. A relay driver circuit is a circuit which can drive or operate a relay so that it can function appropriately in a circuit. At the initial condition when switch is open no current flow through coil hence common port of relay is connected to no normally open pin so the. A temperature controlled relay circuit.

A relay accomplishes this by using the 5v outputted from an arduino pin to energize the electromagnet which in turn closes an internal physical switch to turn on or off a higher power circuit. So let s make this simple circuit. You can use them to turn off a large motor if gets too hot or turn on a heater if the. Let us discuss the working of the project.

Today in this article we are going to make a led flasher circuit with a relay. This is a simple circuit based upon a multi color led and a general npn transistor. A 5v voltage regulator is used for giving 5v regular supply to the circuit. An on off switch is added for the switching purpose of the relay.

Thermistors are really useful with 5v relays. Here we have used 9 v battery and 5v optional relay for switching the ac load. In the above circuit 5v relay is powered by a 9v battery. A simple project in which arduino uno controls a 5v relay is explained here.

Note that a0 and d0 connect to the micro controller and the 5v and ground to the right of the diagram. As mentioned earlier by interfacing arduino with 5v relay module we intend to operate an ac load like lamp. Here is a schematic diagram for a simple circuit that uses a 9 vdc circuit with a handheld pushbutton to turn a 120 vac lamp on and off. Relay switch circuit diagram working of the basic 5v relay circuit.
