Unijunction Transistor
The Unijunction Transistor or UJT for short, is another solid state three terminal device that can be used in gate pulse, timing circuits and trigger generator applications to switch and control either thyristors and
Power in AC Circuits
In a DC circuit, the power consumed is simply the product of the DC voltage times the DC current, given in watts. However, for AC circuits with reactive components we
BH1750 Ambient Light Sensor with Arduino
In this project, we will learn about the BH1750 Ambient Light Sensor Module and also how to interface a BH1750 Ambient Light Sensor with Arduino to obtain the ambient light
Phasor Diagrams and Phasor Algebra
Sinusoidal waveforms of the same frequency can have a Phase Difference between themselves which represents the angular difference of the two sinusoidal waveforms. Also the terms “lead” and “lag” as
Three Phase Transformers
Thus far we have looked at the construction and operation of the single-phase, two winding voltage transformer which can be used increase or decrease its secondary voltage with respect to
Smart Dustbin using Arduino, Ultrasonic Sensor & Servo Motor
In this project, I will show you How to Make a Smart Dustbin using Arduino, where the lid of the dustbin will automatically open when you approach with trash. The
The Inductor
In our tutorials about Electromagnetism we saw that when an electrical current flows through a wire conductor, a magnetic flux is developed around that conductor. This affect produces a relationship
Resistors in Parallel
Unlike the previous series resistor circuit, in a parallel resistor network the circuit current can take more than one path as there are multiple paths for the current. Then parallel
The D-type Flip Flop
One of the main disadvantages of the basic SR NAND Gate Bistable circuit is that the indeterminate input condition of SET = “0” and RESET = “0” is forbidden. This state will

Transistor Tutorial Summary
Having looked at the construction and operation of NPN and PNP bipolar junctions transistors (BJT’s) as well as field effect transistors (FET’s), both junction and insulated gate, we can summarise
Interfacing Voltage Sensor with Arduino – Measure up to 25V using Arduino
In this project, we will learn how to measure voltages using Arduino by interfacing a Voltage Sensor with Arduino. Using this Arduino Voltage Sensor interface, you can measure voltages up
