Hacks of Electronics
Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
Dear friends, in this post I’ll guide you step by step about interfacing ESP32 with SG90 servo motor. It is very similar to interfacing the SG90 servo motor with the Arduino board. So without wasting time let’s get started, first I’ll tell you what are the important component that will required to complete this entire […]
In this IOT project, we will see how to make a home automation system using ESP32 and Blynk mobile application. We will use Blynk mobile application to control our ESP32 dev module. This system can work with or without internet. Also, this system can be controlled manually using push buttons. Components Required for Home Automation […]
How to install Raspbian on Raspberry pi? if you had taken the raspberry pi with its kits then it has pre-installed OS and you don’t need to install the Raspbian OS, but in the future, if you face any difficulties while booting the raspberry pi then this blog surely going to be helpful for the […]
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. […]
