IR Remote Control Light Switch using CD4017

IR (Infrared) Remote Control Switch Circuit is a cost-effective solution for home appliances in our fast-paced life. As a result, much importance has been given to this aspect and a range of remote controls are prevalent today. One of the most frequent is that which makes use of IR radiations at particular frequencies for operations. So In this tutorial, we are going to make an “Infrared IR Remote Control Relay Module” by using TSOP1713 & CD4017 Decade Counter IC.
