Arduino Relai(s) – So schaltet man ein Relais mit Arduino. Bei der Standard-Beschaltung eines Relais wird der Steuerstromkreis durch einen digitalen Pin des Arduino-Boards geschaltet. Dazu muss zunächst das digitale Signal durch einen Transistor verstärkt werden. Der Transistor schaltet dann das Relais.
I'm thinking about putting together the circuit based on the schematic I drew up in the attachment. Would there be a way that would work better? I'm a bit confused by the base current to the transistor in the upper left hand corner. It seems like I would need a larger resistor 2020-01-03 · That’s all on Arduino Relay Tutorial: Control High Voltage Devices with Relay Modules! Now that you know what is the relay and how it works, possibilities are endless as you can control many high voltage devices using various devices like the TV remote, Bluetooth, internet, etc with the Arduino. We hope you’ve found this guide useful.

So if I want to turn a light ON, the Arduino closes the relay (on the relay board) during 150 milliseconds which creates an impulse and turns the impulse relay ON (the Arduino acts as push button). It works since 2014 but I'd like to get rid of the Chinese relay boards to make a "clean" installation. A relay is a programmable electrical switch, which can be controlled by Arduino or any micro-controller. It is used to programmatically control on/off the devices, which use the high voltage and/or high current.

It is a bridge between Arduino and high voltage devices. In general an Arduino cannot provide enough current to trigger the coil in an electro-mechanical relay even if it has a 5v coil.

Middle one is COM (common) and the rest of the two are called NO (Normally Open) and NC (Normally Close). The relay I am looking at is a SRD-05VDC-SL-C. It is very popular relay among Arduino and DIY electronics hobbyists. This relay has 5 pins. 2 for the coil.
