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 […]
LED Oscilloscope Circuit
The simple LED oscilloscope circuit I have explained in this article can be used for analyzing low frequency waveform through a 10 x 10 LED matrix display. Due to the involvement of only 100 LEDs in the display board, the resolution is low, and the waveform display clarity is not so impressive. Yet, this LED […]
How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
Solar Stud Light Circuit
In this post I am going to explain solar road stud light, what is it? How do they work? And how can we construct our own. In this post we will see the following: What are road stud lights? What are active and passive solar road stud lights? Circuit design and diagram. Flashing stud lights […]
Simple Temperature Indicator Circuits using Thermistors
A thermometer may be required for the precise measurement of temperatures. However, in many cases, an absolute value isn’t required and a relative estimate is sufficient. For example, the consumer may be alerted to the fact that an electric drill or vacuum cleaner is becoming hot, through a basic LED illumination, or through changing color […]
