In the following LED chaser circuit concept, I will explain how the circuit sequentially turns on and off 16 LEDs using a 24 pin decoder IC 4514. A four-bit binary input is used by the CMOS 4514 binary-to-decimal decoder, IC3, to go forward and activate each of the 16 outputs. How the Circuit Works The […]

100 to 200 LED Reverse Forward Chaser Circuit for Diwali, Christmas Decorations
In this post I will discuss how to build a simple LED chaser circuit with a push pull or reverse forward sequencing effect. Also, in the later part of the article I have explained how this simple LED chaser could be upgraded to a 100 to 200 LED laser circuit with a reverse forward LED […]
Car Reverse Horn Circuit
A crucial safety element in cars is the reverse horn, sometimes referred to as the reverse warning device or backup alarm, which emits an auditory signal while the automobile is in reverse. The reverse horn, which is intended to improve pedestrian and occupant safety, generates a unique sound to alert others around that the vehicle […]
Car Reverse Parking Sensor Circuit with Alarm
In this post I will show how to construct a car reverse parking sensor alarm circuit using arduino, ultrasonic sensor and 2.4 GHz transceiver module. This project can be add-on feature for your car if it doesn’t sport a build-in parking sensors. Introduction The proposed project has similar functionality as traditional car parking sensor has, […]
40A Diode with Reverse and Overvoltage Protection
In this post we study an outstanding high current diode which features not only an in-built reverse current protection but also an over-voltage protection for safeguarding sensitive electronic circuits against back emfs, transients and load dump occurrences. How 40 Amp Diode RBO40-40G/T Works The device RBO40-40G/T from STMicroelectronics comes in a TO-220 package and looks […]
Toy Motor Circuit with Timed Reverse Forward Action
In this post I have explained a simple programmed reverse forward motor circuit which is used for accomplishing a toy application. The idea was requested by Mr. Matthew. Technical Specifications I am a new follower of your website which is a great resource! I need your help designing a circuit please. My daughter has a […]
