What is DIAC: Construction, Working and Application in Triggering the TRIAC
DIAC is a semiconductor device which has three layers and two junctions. The word DIAC consists of two parts, DI and AC. The DI stands for the diode (or two. Like Di, Tri, Quad, Penta etc.) and AC stands for Alternating Current. DIAC is the acronym of the diode for alternating current.

ESP8266 Interfacing with ARM7-LPC2148
In this tutorial we will interface an ESP8266 Wi-Fi Module with the ARM7-LPC2148 microcontroller and create a webserver to control the LED connected to LPC2148. The workflow will go like this:Send AT commands from LPC2148 to ESP8266 to configure ESP8266 in AP modeConnect the laptop or computer Wi-Fi with the ESP8266 Access pointCreate a HTML webpage in PC with Access point IP address of the ESP8266 webserverCreate a program for LPC2148 to control the LED according to the value received from ESP8266

Robotic Arm Control using PIC Microcontroller

Robotic Arm Control using PIC Microcontroller

In this tutorial we will use the industry standard PIC16F877A 8-bit Microcontroller to control the same robotic arm with potentiometers. The challenge with this project is that PIC16F877A has only two PWN capable pins, but we need to control about 5 servo motors for our robot which requires 5 individual PWM pins. So we have to utilize the GPIO pins and generate PWM signals on PIC GPIO pins using the timer interrupts. Now, of course we could upgrade to a better microcontroller or use a de-multiplexer IC to make things a lot easier here. But still, it is worth giving this project a try for the learning experience.

What is VFD Drive Circuit: Its Operation, Types and Applications

VFD is the short form of a Variable Frequency Drive or adjustable frequency drive. The frequency determines the motor RPM and by controlling the AC frequency the motor RPM can be controlled. Different types of VFDs are available in the electronics and electrical market ranging from small motor related applications to the high power induction motors. Other than the three-phase VFDs, single phase VFDs are also available.

7.4V Two Step Lithium Battery Charger Circuit – CC and CV mode

The advancement in Electric Vehicles, Drone and other mobile electronics like IoT Devices seems to be promising for the future. One common thing among all these is that they are all powered by batteries. Following Moore’s law the electronic devices tend to become smaller and more potable, these portable devices should have their own source of power to operate. The most common battery choice for portable electronics today is Lithium Ion or Lithium Polymer Batteries. While these Batteries have a very good charge density they are chemically unstable under harsh conditions hence care should be taken while charging them and using them.

Soft Start Circuit for Power Supply

Soft Start Circuit for Power Supply

A Soft Start Circuit prevents the sudden current flow in the circuit during the start. It slows down the rate of rising output voltage by minimizing the excess current flow during the start. It is useful to protect the devices or electronic components from the damage caused by instantaneous high input current. Some components which are current limited and having poor load regulation can get damaged because of this high input current. Here we are building the soft start circuit using a voltage regulator IC LM317 and a PNP transistor BC557.
