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 […]
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 […]
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. […]
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 […]
Introducing the musical 16 Tune musical doorbell circuit diagram, it produces a different musical tune each time the bell push button is pressed. The bell produces a total of 16 tunes which follows successively. Music Doorbell is a harmonious fusion of functionality and creativity that transforms the mundane act of answering the door into a […]
This low cost and non-partial Digital dice roller ensure a fair play and equal chance to all participants. Small enough to be carried around in a pocket, it would prove to be an ideal companion in indoor and outdoor games like ludo, Snake & Ladder, etc. Since times immemorial the six-faced cube, ever since the […]
