This instructable will show you how to control stepper motors (Unipolar OR Bipolar) manually with a knob, without the use of a PIC or PC, so no programming is needed.  The position of the knob determines the position of the motor shaft, which will stay in that position until the knob is turned again.  The […]

PIC16F877A is an easy micro controller for the beginners Here in project: 1) How PIC switches servo motor forward and back ward When we push one switch it goes to positive 90 degree , on second switch it moves backward to  negative 90 degree a. MickroC  PRO        // for programming of MICRO CONTROLLER b. Proteous  […]

** Schematic diagram corrected and updated ** In my previous post, I slapped together a quick LED lighting solution for my workbench… but it is truly a hack. What I really want to do is make a simple constant current driver, so the power LEDs can be used in other projects. One of those projects […]

If you’re into electronics, engineering and making things move, you’ll need a good handle on electric actuators. Use this beginner’s guide to electric actuators before you set out to purchase your first actuator. What is An Actuator? Before linear electric actuators were around, the only way to make a robot move forward was to use […]

I have built this project to burn my small PIC’s This is a serial programmer works on the RS232 ( PC serial port ), known as JDM Programmer, thanks to the site http://pic16f84.hit.bg/ which contains the schematic and the programmer software. The programmer is powered from the Serial port itself, so there’s no need to […]

PIC microcontrollers are a very useful and versatile tool for use in many electronic projects. They are very inexpensive and easy to find. They are also very powerful and many are capable of speeds up to 64 MIPS using the internal oscillator block, about 16 times faster than most comparable AVR microcontrollers. PICs are also […]

Description Project is based on Holtek’s IC HT7610A, which is a CMOS LSI chip designed for use in automatic PIR lamp, flash or buzzer control. It can operate in 3-wire configuration for relay applications.  In our project we have used relay instead of Traic to connect any kind of load in output, HT7610B IC is […]

Many electronics people will build a bench power supply at one point in their professional or hobby career. I too have made a couple over the years. However, most of the time I used what was available in the shop(s) where I did my work. One type of PSU in particular always fascinated me: a […]

PLC (Power Line Communication) is the technology that allows data transmission over the existing Power Line network. Power Line can be the home power network or the national electricity transmission grid. The data that can be transferred is as diverse as its speed. With speeds of nearly 200Mbps, video transmission, voice, data and any other services can be […]

You may have heard about the phenomenon of bypassing in circuits, however, we may not have sufficient knowledge of how to apply this technique in real circuits. In this tutorial, we will discuss about the bypass capacitors, why we need to use and how to use these capacitors in circuits. What is a Bypass Capacitor? […]
