Interactive Blitz Chess A Physical Blitz Chess Board Powered with PIC32

Interactive Blitz Chess: A Physical Blitz Chess Board Powered with PIC32

Introduction We created a companion system for physical chess boards to help players enjoy their fast paced blitz game with a chess clock, a visual board to keep track of the game, a display for available moves based off of what piece that players want to move, and also a log of past moves made […]

binary clock using a PIC

Making a binary clock using a PIC16F88

You can use a PIC microcontroller and an LED matrix to create a binary clock (or if you prefer you can wire up individual LEDs). This project uses an LED matrix block as it saves lots of wiring.  So what is it ? Its an led clock that displays the time information as binary numbers… […]

dsPIC30F2012 breadboard

dsPIC30F2012 breadboard

Bernard introduces us to the dsPIC microcontroller. He shows us his Arduino like project board for a dsPIC and gives advice on software development tools. This article was submitted by Bernard Klinc as part of the “Hobby parts for articles” program. Bernard received a graphic LCD module for this great article. You may remember Bernard […]

FTS 8 subtone encoder

FTS-8 subtone encoder

Many Yaesu transceivers from the 1990s and thereabouts could use an optional FTS-8 module, that provided subtone generation for transmission, and subtone decoding for CTCSS reception. One of the radios that used this module was the FT-736 multiband, multimode full-duplex VHF-UHF rig. I bought one of these radios in 1992, to use it on the […]

Hand Sign Lock

Hand Sign Lock

Introduction Security using technology is a growing and expanding field to protect against the user’s identity or property. As more advanced tools are developed, security has begun to expand to utilize a person’s physiology as a key instead of a password; for example, newer models of IPhones by Apple have fingerprint sensors as an option […]

Arduino to PIC Communication

Arduino to PIC Communication using PIC18LF4520

One very common thing in electronics is the need for two intelligent devices to communicate with each other. When you first see a PIC and Arduino you might think that they are two differeny systems and don’t share much in common, but you’d be wrong! In fact, the AVR and the PIC microcontrollers have many […]

Voice controlled wheelchair

Voice controlled wheelchair

The Project aims at controlling a wheelchair for handicaps by means of human voice. The speech recognition system is a useful way of implementation and is easy to use programmable speech recognition circuit. Programmable, in the sense that user can train the words (or vocal utterances) he needs the circuit to recognize. This board allows […]

Two way Simple Very Small Telephone Exchange

Two way Simple Very Small Telephone Exchange

This is a very small telephone exchange attached only two ordinary Tele phones. Fully bi-directional facility with an intercom system. When a phone is in off hook condition , Exchange will detect it & send ringing pulse to other phone. When it will be picked up , the connection will be established between both phones. […]

interface keypad with PIC12F675

How to interface keypad with PIC12F675

This post provides a simple method to interface any keypad (e-g 4×4 or 4×3 etc) with PIC12F675 microcontroller. The code for PIC12F675 is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom of this page. In this post, it is assumed that you know, […]

Barcode Scanner

Barcode Scanner

Introduction In our final project, we used CMOS camera to identify interval binary 0 and 1 sequence represented by black and white bars. Then, we used WIFI module to transmit the sequence to personal computer and displayed it on a web page. In our projects, we chose OV7670 CMOS camera and ESP8266 WIFI module for […]
