Summary Arduino compatible AC voltage dimmer with push buttons
Let’s say you dim a ceiling fan or incandescent light. You can do that with the help of “Programmable AC Voltage Dimmer” of techshopbd.com. But that module requires an Arduino and some advanced programming skills. What if you want to control voltage with just two push buttons? Or you don’t have advanced programming knowledge. Then this is the right module for you.
WHY YOU SHOULD USE IT?
It is very easy to control DC voltage with AnalogueWrite() function of Arduino . But household electrical equipment like ceiling fan, incandescent bulb, water pump etc. runs on 220 volt alternating current (AC). To control those equipment’s input voltage you’ll need this module and a 3.7-5.5V battery. That’s it.
Just pressing big yellow buttons you can increase and decrease input voltage. If you don’t want your hands dirty and prefer to press buttons electronically then hook an Arduino with it. Setting + pin to Low and – pin to High for at least 100 millisecond. Then you’ll have the ++ button pressed. Do the opposite to press - - button.
NB: This device does not support CFL & Tube Light.
