Learning Board for PIC12F683 Microchip

Introduction Electronics is my hobby. When I was in college I had some experience with microcontrollers; I did few projects with Atmel’s AT89C51. Recently, I have grown interest on PIC microcontrollers, and I thought I should start with 8-pin microchips. I picked PIC12F683 microchip. This microcontroller fascinated me a lot because I wanted to see

PIC16F877A (with LCD) not working

I have designed a PIC18F877A micro controller project to read temperature from an LM35 using ADC, display it on an LCD and transmit it to a serial port. When the program starts, sometimes it shows a startup message – sometimes it doesn’t display anything. Also, the serial port connection is not working. Can anyone help

Ultrasonic Position System

The ultrasonic position system uses ultrasonic transmitters/receivers to triangulate position of the robots used in GE423. Each of three transmitters uses a distinct frequencies: 23 kHz, 31 kHz, and 40 kHz. The 2812 DSP is used to measure signal timing and calculate position based on these values. The design of the electronics, as well as

Standalone BreadBoard Breakout for PIC Microcontrollers

I wanted to make a breadboard breakout for PIC microcontrollers after seeing this arduino breadboard breakout from adafruit. This product is fully standalone and yet has very small footprint so that it can be conveniently plugged into the breadboard. The most amazing part was that it still had 2 rows on each side of the breadboard for the
