What Are Optoisolators And Optocouplers, How They Work?

Optoisolators and Optocoupler sound very similar and they are the same in terms of workings and other features let’s see what are optoisolators and optocoupler. There are some differences due to which they are given different names. Photocoupler is another name of the optocoupler. An optocoupler or photocoupler and an optoisolator are semiconductor devices that […]

L293D Pin Diagram, Working and Interfacing of L293D with Arduino

In this blog, we will discuss about L293D Pin Diagram its working, and its interfacing with Arduino. L293D can drive two DC motors simultaneously, with up to 600mA current in each channel. It receives a control signal from microcontrollers such as Arduino, ESP32 Dev Module, etc. based on these control signals it controls the direction […]

Ultrasonic Sensor Without Arduino using 555 timer

Hey folks, have you used an ultrasonic sensor in your projects! Do you know how it works? In this project, we will use an ultrasonic sensor without Arduino for object detection. We will interface ultrasonic sensor with a 555 timer to control a DC motor. How ultrasonic sensors work? As the name suggests an ultrasonic […]
