Modules for turning on any load with one button for any device
In this video I will show an overview of electronic switch modules. With their help, you can turn the load on and off with just one button. There will be two modules in the review, one low voltage and the other high voltage. The first can be powered from power banks or lithium batteries, and the second from twelve volt batteries or power supplies from 12-24 volts. Up to 10 amperes of current can be supplied to the load through the modules.
The button module Compatible with popular electronics platforms like Arduino, Raspberry Pi, and Esp8266. It consists of a push-button switch and a resistor.
This tutorial shows the basic use and testing of the three-pin push-button module with Arduino and Raspberry Pi. An Arduino sketch shows how to read the push button module to determine if its switch contacts are open or closed.
Pulse Relay is used to control lighting or other devices by means of mono modular pushbuttons connected in a parallel way. Pushing any button causes switching ON or switching OFF the devices connected to output terminals.
** I had a few sound issues with some of the experiment scenes, the isolation transformer I was using interfered with one of my microphones, so I had to back it off and apply a sharp 60Hz parametric filter. I apologize if it sounds a bit weird in spots! **
In an earlier video, I showed you how to control DC devices with an Arduino using BJTs and MOSFETs. Today we will learn how to control Alternating Current or AC devices. And, most importantly, I’ll show you how to experiment with AC in a safe and controlled fashion.
Controlling AC using semiconductors is a challenge, as most transistors only conduct current in one direction. One type of semiconductor that will do the job is the TRIAC, which itself is essentially a fusion of two Silicon Controlled Rectifiers, or SCRs.
Another way of controlling AC (or DC for that matter) is a good old-fashioned relay. Although relays have been around for over 180 years they are still a popular and practical solution for controlling AC devices.
One extremely important issue when controlling line-voltage (or mains voltage, if you prefer) AC current is isolation. You need to make absolutely sure that there is no electrical connection between your low-voltage logic circuitry and the high-voltage AC.
An excellent device for achieving this isolation is an optoisolator. This device separates the two circuits with a beam of infrared light, completely isolating them.
Put an optoisolator together with a TRIAC and you have a Solid State Switch, or Solid State Relay (SSR). Combine an optoisolator with a relay and driver transistor and you have a Relay Module. We'll be using both of these devices with an Arduino today.
