Designing a circuit to switch on a light at dusk and off at dawn is straightforward, and many such designs have been featured in EFY. However, lights controlled this way remain on all night, resulting ...

Positive feedback is primarily used to rapidly amplify a desired change or signal, often in situations where a large response is needed, like triggering a process to reach a specific threshold quickly ...

Hiwonder’s MechDog is a compact AI robot dog powered by an ESP32-S3 controller that drives eight high-speed coreless servos. It features built-in inverse kinematics for precise and agile movements and ...

This cooker is energy-efficient, keeping food warm due to thermal insulation, with cooking times ranging from 1 to 1.5 hours. The block diagram of the proposed cooker is shown in Fig. 1. It employs an ...

Infrared line tracker modules hardly need an in-depth explanation as they’re very familiar to most electronics and robotics hobbyists. In this post I’ll discuss a popular and cheap infrared line ...

In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

Function generator or waveform generator is an integral part of electronics and used to produce various kinds of waveforms like a sine wave, square wave, Sawtooth wave, etc. We have already designed ...

Protection circuits are vital for any electronic design to be successful. In our previous protection circuit tutorials, we have designed many basic protection circuits that can be adapted into your ...
