This project shows how to build a very simple yet very useful tool that every DIY enthusiast should have in his lab: a 100MHz+ frequency counter. The schematic is fairly simple and straightforward and uses a PIC16F628A microcontroller for measuring frequency and a high speed...

This tiny Unipolar stepper motor driver has been designed around SLA7078MPR IC from Sanken. It is a unipolar stepper Motor driver that can handle current up to 3 Amps and has micro-stepping up to 1/16 steps. On-board Jumpers are available to set the Micro-stepping and Preset...

Audio Dancing LED project is a fun filled project which generates a LED dancing sequence depending on the audio level it senses.  This project is based on one of the VU Meter IC LB1403 or CA1403 Specifications Power supply input 6 to 9 VDC Output 5 LED's Onboard preset to...

LED Flasher is a simple project producing a flashing effect of six LED's.  This project can be used in all areas where you want to draw attention.  Hi-glow LED's providing enough flashing light to attract your attention. Can be used as warning light. Specifications Supply input...

Versatile project has been designed to use in automotive application and industrial servo control application. This project provides all active necessary functions for closed loop servo system using Brushed DC Motor and potentiometer mounted on output shaft of DC Motor Gear. This...

Digital Panel Meter performs digital processing on or conversion and display of voltages, currents, other analog signals, and pulse signals. This project is based on popular ICL 7107 IC, which is analog to digital converter and has been designed to drive 7 segment LED display. The...

This project can be used to power up TTL and CMOS based projects, it provides 5 VDC & 12 VDC outputs with an onboard mains transformer.  The project is based on the industry popular 7800 series voltage regulator in TO220 packages. Features Input: 240 VAC Output: 5 V, 12...

Light / Dark Sensitive Switch project is a simple project which operates a relay when the light falling on the LDR goes below or goes above a set point. Input - 12 V @ 50 mA Relay output - SPDT relay 2-in-1 kit, either as light sensitive kit or dark sensitive switch Onboard...
