In the past two weeks, I discussed the prerequisits for starting your first application and the issues surrounding PICMicro programmers and what to look for. With this background, I am now ready to present what I think is a good first application for somebody learning about the PICMicro. This circuit is not as simple as […]

Red digits on this photo appear to float in the air in front of the clock. This illusion is based on inertia of a human eye. If LED-formed digits will periodically and frequently enough flash, they will appear solid and steady. And since the matrix of digits is formed by a mechanically scanned single line

description This is my electronic combination lock to use with an outdoor gate. The functionality is implemented in software. It turns on a relay (usually to open a door) for a few seconds if someone enters the valid code. Alternatively, it works as an ON/OFF switch, which toggles the relay each time the code is

Design Goal: The JavaBot1 is a small line following robot designed to follow a black line drawn on a dry erase board. It is designed to follow very tight curves. The software still has lot’s of room for improvement but works well as is. Motive Power: The JavaBot1 uses 2 Cirrus CS-70 servos that have

Caption (copied from the NorCal meeting listed in the links below): IK3OIL Frequency counter built by Wayne McFee. This is from IK3OIL’s web site, and the cost of the counter was about $2, minus the display, which was about $7. Wayne got the source was www.shopeio.com. They are located in Gardenia, California. Design and Code

This is a project that I started back late 2003 when I just starting to learn PIC programming. I wanted to building something that actually did somthing useful. This project is based on a PIC16F84. I actually came up with this idea and then after doing some searching I found that a few people had

I’ve wanted to build a sonar for a while now, and I was hoping to be able to do it with a design someone else had made, but alas, I’ve never had much luck. I’ve done many searches of web pages, and all that ever comes up are sonars that give a single range to

It’s a kitchen timer. Use it to time spaghetti, or maybe an egg. It uses two PICs, one acts as a keyboard encoder, the other drives the display and supports the timer functions. You key in the desired time and press ‘#’. It’s accurate to 1/100th of a second, which can make all the difference
