Let’s do a small project to learn how to use an electro-mechanical relay with An Arduino. To know more about relays and types of relays read this article “Relay In A Nutshell“, where I explained everything in detail. Project concept We can create a light-activated relay circuit with the help of Arduino that will automatically […]

Let’s learn to use an LDR sensor or photoresistor with BBC micro:bit. This is a very simple project. We are going to print “BRIGHT” in the inbuild LED matrix of the micro:bit if there is light in the room or else “DARK” will be printed.
