In this article I have explained a simple line follower robot circuit, also known as line tracker vehicle, using just a couple of op amps from the IC LM324 and a few other components, without using complex Arduino or microcontrollers. It means this project can be built without any coding, just by using discrete components, […]
Newly Updated Circuit Projects:
Smart Street Lamp Circuit with Motion Sensor
This simple yet highly sophisticated, smart LED street light circuit automatically switches ON a street lamp from low brightness to high brightness whenever it detects a moving object underneath it. This action is initiated only during nighttime, while during daytime the street lamp remains completely shut off. What this Circuit will do This advanced automatic […]
Day/Night Triggered Automatic Door Lock Circuit
In this post I have explained a simple day, night triggered automatic door lock circuit, which can be used for autonomously unlocking a kennel door during day break, and locking it when night sets in. The idea was requested by an avid reader of this blog, Mr. Norman, as given below. Design Request and Specifications […]
Automatic Night Activated Wireless Light Circuit for Paintings
In this article I have explained a basic wireless LED light circuit that may be used to autonomously turn on LED lights to illuminate artworks at nighttime.
75 Watt Power Amplifier Circuit
Our power amplifier only uses a handful of widely available and inexpensive components. Despite this, it can deliver an effective power output of 50 W into an 8 ohm load or 75 W into a 4 ohm load. If distortion is below 0.3% at these maximum power levels, it drops to less than 0.01% from […]
Analyzing Class B and Class AB Amplifier Models
Both the majority of class B or AB power amplifiers currently encountered in HI-Fi amplifiers are presented in the form of integrated circuits specifically designed for this purpose. It is interesting for technicians to know how this type of amplifier works, if only out of intellectual curiosity. The provided model allows the study of several […]
