This project, called “Mini-Beacon”, is a miniature programmable LED Flasher that is based around the PIC microcontroller.  This project grew out of an idea and recommendation posted on RunRyder.com.  The Mini-Beacon basically simulates the light emitted from a rotating light beacon such as those used in older police cars and fire engines.  As seen from the observer’s […]

Teddy nightlight multicolor A nice night light multicolor, ideal for baby’s room. For the realization I used: – Out of a pack of bubble bath for children in the shape of teddy bear – a nightlight with positive economic pressure – Complete circuit with a PIC16F84A (I was at home, but you can use any […]

Exciting! A new product of my design just hit the market last week! World, meet Pixie – a 3W chainable smart LED Pixel. Kind of a long title… what does it mean? LED Pixel: The Pixie is a color LED module, allowing an external controller to change its color and brightness dynamically. Chainable: The module […]

TI’s new bq25890, bq25892, and bq25895 5A chargers with TI’s MaxCharge™ technology charge your mobile device faster while keeping your device cooler. The switch-mode chargers can charge a 1-S Li-Ion cell to 80% capacity in 30 minutes, while traditional devices only reach 30%. The I2C-controlled chargers’ high efficiency and thermal management result in the fastest, […]

A Digital Clock can be made easily by using PIC Microcontroller, DS1307 and a 16*2 LCD. I have already posted about Interfacing DS1307 RTC with PIC Microcontroller. The DS1307 RTC can work either in 24-hour mode or 12-hour mode with AM/PM indicator. It automatically adjusts for months fewer than 31 days including leap year compensation […]

Here I give you tutorial of Project on making calculator using PIC16F877 and Mikcro C Pro. After go through this project and learn the technique you can implement in your project. In my previous post I show you how to interface keypad 4 x 4 matrix’s  If you not see that you should go through it […]

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 project is ideally suited for almost any servo positioning application. Features POWER SUPPLY: […]

This post provides the code for interfacing DS1307 RTC with PIC16F84A microcontroller. This DS1307 RTC has i2c based interface and PIC16F84A doesn’t have any built in i2c modules, so software i2c module is created in the code. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom […]

Digital isolators based on transformers and capacitors use magnetic and electric fields to couple data across isolation barriers where optocouplers use light. Digital isolators can be manufactured using CMOS technology allowing the integration of signal conditioning circuitry in the chip to greatly reduce power consumption and improve data transfer rates. The iCoupler family from Analog […]
