Introduction This page describes a project a colleague and I completed between September, 2000 and March, 2001 as part of the Engineering Physics degree program at the University of British Columbia. In summary this project involved building a USB device using the PIC 16C745 microprocessor from Microchip. The USB device consisted of a microphone, the […]
This project uses Myke’s 2-Wire LCD Interface from last week and will help teach you “Graphics Animation” using LCD’s. Last week, I showed how the PICMicro could be connected up to a Hitachi 44780 LCD using only two wires. This week, I wanted to use this circuit and show how simple graphic animation can be […]
I wanted to build a clock as simple as possible : built around a little 18 pins PIC no 7 segment display, only LEDs no decoder, no buffer, no driver for the LED display a cheap temperature sensor The solution of direct LED driving comes from a Microchip Application Note AN234, and as I’m using 25 […]
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 […]
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… […]
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 […]
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 […]
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 […]
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 […]
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 […]
