Relay Guidance General Electronics Arduino Forum In my project i need to use relays to turn off certain items when needed but most of the time they would be running 24 hours a day 7 days a week continually. is it safe to have a mechanical relay energised constantly or will its coil burn out?. Since it uses up to 80ma, i cannot connect the datalogger's x1 directly to an arduino digital pin, so i have to use a relay that keeps the data logger's circuit separate from that of the arduino.

Relay Control With Arduino General Guidance Arduino Forum In this tutorial we will learn how simple it is to use arduino 4 channel relay shield to control a 12v light bulb. in first example the light bulb will just blink and in the second example we will turn on or off the light bulb using a button and in a third example using a remote control. My project is to use an arduino uno to read an automotive thermister temp sensor and a temperature switch in order to control the operation of an oil cooler in a car. Understand how relays operate, how to wire them correctly, and how they’re used to control high power devices in electronics and electrical systems. Post the current sketch, schematic and a function description to see how we can help. trying to get arduino 4 to fire 8 relays, but in sequence with 1 external trigger to activate each relay 1 time.

I'm using a wpm400 relay module, the schematic is here: i will be using this to switch 230v solenoid valves, but i have an arduino nano esp32, which is a 3.3v mcu, and this relay needs 5v. Now i want to add extra larger lights as well as the small leds via a relay and using a 12v power supply for the larger lights controlled by the arduino. anyone help ?. Connecting solenoid valves with arduino, hc 05, and relay module projects general guidance dubduino july 15, 2025, 9:05pm. Hey all so, a friend and i are making a mini clock tower, and i'm handling the sound signals with an arduino uno r3, ds3231, srd 05vdc sl c relay, and a kk 0630b strike magnet. the relay and strike magnet are powered through the arduino. the current never exceeds the arduino limit, so i think it should be fine. every hour, i activate the strike magnet to strike the bell so you can hear what.
