Short Circuit Protection Using Relay For Batteries

In this tutorial, we will see how to make a short circuit protection using Relay. Many times accidentally terminals of batteries and other power supplies get short-circuited. Due to this, they get hot and start degrading. In the case of lithium-ion or lithium-polymer batteries, they may catch fire due to short-circuit or even get blast. […]

Automatic Night Lamp Circuit Diagram by LDR & LM358 OPAMP

This article explains an automatic night lamp circuit diagram using LDR and LM358 OPAMP which automatically turns the LEDs ON at night and OFF when it is daytime. The sensing part which is being used for detecting the light is a Light Dependent Resistor (LDR). The resistance of LDR depends on the light incident on […]

FM Transmitter Circuit Diagram and Working

In this post, we will see FM Transmitter Circuit Diagram. FM transmitter broadcasts the signal from any audio device to a standard FM radio. This transmitter is open when the signal has to be reached to some long distance.FM means Frequency Modulation. It carries the audio signal (20 – 20kHz), then it is being loaded […]

Bluetooth Controlled Car using ESP32 and Android phone

In this project, we are making a Bluetooth Controlled Car using ESP32 Dev module. There is a reason why we have chosen ESP32 instead of any other board like Arduino. here is the reason why we have chosen it. ESP32 is now becoming more famous due to its great features like inbuilt Bluetooth and Wi-Fi modules. Also, it has […]
