This is a common accessory module for electronic DIY fans. Equipped with a high current relay. Its max current can be up to 2A. Adopt a 3V power supply, which is enough to support micro:bit. Contact control, including a normally open contact and a normally closed contact. Convenient wire connection. Hardware Connection Connect the relay module to P1 on octopus:bit using a jumper cable. Insert micro:bit into the edge slot of octopus:bit. Click to open Makecode, and write your code in the editor area. Set high electric level to P1 port to make the normally open contact close and the normally closed contact opens. Thus, we are able to control the connection of the contact switch through code.

Working with relays in combination with higher AC voltages is dangerous and can cause damage to yourself or a fire. So, it is intended for people with experienced and knowledgeable about higher AC voltages. For permanent use, make sure to use a relay for housing technology and not microelectronic. A relay is an electrical switch which toggles on and off by energizing a coil. The coil is made of wire wrapped around an iron core to provide a low reluctance for the magnetic flux.

This article shows how to control mains voltage with the Arduino using a relay module. We make a brief introduction to the relay module and build a simple project example with the Arduino. By the end of this tutorial, you should be able to control any electronics appliances with your Arduino using a relay module. A relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5V provided by the Arduino pins. This relay module has two channels those blue cubes. There are other models with one, four and eight channels.

Selecting the appropriate 3 volt DC relay requires consideration of the electrical specifications and the intended application. Wish List Compare. The compact size of a 3V DC relay makes it suitable for space-constrained environments, while its low operating voltage aligns with modern low-power electronics. Convenient wire connection. From single-pole single-throw SPST to more complex multi-pole double-throw MPDT configurations, these relays are integral in automotive electronics, home appliances, and power systems. Choosing the Right 3V DC Relay Selecting the appropriate 3 volt DC relay requires consideration of the electrical specifications and the intended application.

Using a low-current signal, these relays are often used to control small motors and heaters. Prevent damage from voltage spikes, reduce signal interference, and amplify signal with these relays, which interface between your controller and components to isolate input and output circuits.
