The IC 555 is an extremely useful and versatile device which can be applied for configuring many useful circuits in the field of electronics. One very useful feature of this IC is its ability to generate PWM pulses which can be dimensioned or processed as per the needs of the application or the circuit. What’s […]
Newly Updated Circuit Projects:
DIY Taser Gun Circuit – Stun Gun Circuit
A Taser circuit also known as Stun Gun circuit is one non-lethal electric shock producing unit used to paralyze a person for a time being without causing any severe damage or injury. It is a very useful device, especially to immobilize an attacker. Using and making of stun gun is restricted in most of the […]
Interfacing DHTxx Temperature Humidity Sensor with Arduino
In this article we are going to take a look at DHTxx series sensors, which is used for measuring temperature and humidity, both the functionality is integrated into one module. We are going to see their specification, so that you can choose best sensor for your project and finally we are going to interface it […]
RF Signal Meter Circuit
In this article I have explained the circuit details of a couple of very interesting and sensitive RF signal meters, which can be used for measuring the RF strength of the transmitted waves from the RF source without making any physical contacts with the source. Simple RF Signal Meter using IC 741 A RF signal […]
Simple E-Bike Circuit [Electric Bike]
This E-bike or electric bike circuit I have explained below can be used as the control circuit for constructing a homemade E-bike, with the help of a permanent magnet motor DC (PMDC motor), and a Li-Ion battery. An electric bike is basically a bicycle powered through a motor and a battery, which does not require […]
Communication Protocols in Microcontrollers Explained
In this post I am going to explain various communication protocols that are used by microcontrollers, microprocessors and ICs for communicating with various sensors, electronic drivers, input and output devices. We will see: Why do communication protocols exist in electronics? UART protocol. I2C or IIC or “I squared C” protocol. SPI or Serial Peripheral Interface […]
