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 […]

LED Flasher Circuit Diagram with 555 Timer IC
Here we will see the LED flasher circuit diagram and how it works. Flashlights are used in vehicles to pass left-right signals. At many places where two people cannot talk this LED flasher can be useful. We can give signals by flashing lights of different colors. You are familiar with the Bike turn signals indicators. […]
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 […]
