Scalextric Sport Race Start Controller using PIC16F627A

Overview I developed this after my nephews got a Scalextric Sport slot car racing set for Christmas.  The set included a lap timer and counter but one thing that was missing was a way to start a race.  Having someone say "3-2-1-Go" wasn't really doing the job, especially as it was easy to go just after "1" and before "Go"  This works in a similar way to the lights used in F1 motor racing with five lights il ...

Life Size Operation Game using PIC16F877 microcontroller

Life Size Operation Game As a child I loved the Milton Bradley Operation game, the buzzer always scared me when it went off, but it was fun. The object of the Operation game is to remove a body part with out touching the tweezers to the metal sides that surround the object for removal. If you touch any metal sides you make his nose light up and a buzzer will sound and startle you. This year the Church I att ...

Stroop Game using PIC16F628 Microcontroller

This project has been adapted from an experiment by John Ridley Stroop, who published his work in 1935. Basically it is a "trick." It is a trick in that you are required to answer a question at a "second level of thinking." In our test we have three tri-coloured LEDs and below each is a push-button. When a LED illuminates, your immediate response is to push the button below the LED. But this is not the requ ...

Having fun with HC08 using pic microcontroller

Here is a nice little project for a rainy weekend, all this can be accomplished over a weekend and for under USD 15. This page has gone through several rewrites, mainly to get rid of my 'rant mode' writing, but it seems I just need to write it out of myself. Feel free to skip the first part. For references purposes and convenience I've put all the useful links here at the top of the page: Schematics SDCC - ...

A video game with software generated video signal !

Introduction I have made the game pong using a pic 16F84 running @ 12MHz. The game Pong was the world's first video game in the early 70's, this is a modern version of it, made with a little bit less hardware than the original version. In my version, the video signal is generated in software. The only hardware used for the video generation is two resistors forming a 2-bit DA converter. Usually the video sig ...

Color Globe using PIC16F688 Microcontroller

This was a fun little project I put together in a few hours for a homemade-themed gift exchange this Christmas.  I had on-hand a "Full Color LED" from Radio Shack (part 276-0028) which caught my eye on my last visit there. The LED has a common anode and three cathodes, one for each of the three primary colors: red, blue and green.  By changing the duty cycle (the fraction of time the pin is low) on each of ...

Joy Stick Controller using PIC12F629

This project controls two servo motors - both clockwise and anticlockwise and has variable speed. You can use the Joy Stick to "pan and tilt" a remote camera or provide "left-right-up-down" action for a crane or an animation on your model layout. The project also tests servo motors. The CIRCUIT The circuit is fairly simple. The input from the Joy Stick has been separated into two sections to make detection ...

LED message system on a Strida folding bicycle wheel using PIC12F675

LED message system on a Strida folding bicycle wheel After I've bought my strida folding bicycle, one of the first things I've done was to check out instructables.com for any strida related projects. And quite astonished to see that there wasn't any. So I've planned to make an instructable that can be used on my (and also others') strida. I think this is the first (and only so far) project in instructables, ...
