LED Heart PWM Fading using PIC18F252

With my Grandma's birthday fast approaching I wanted to put something together that was not too complicated but still sweet enough to make for a cool widget gift. Since fading LEDs never seem to go out of style and grandmas always love to see a heart, putting two and two together here was a no-brainer. The concept for this small birthday present was to create a small heart shape with red LEDs and then to dr ...

pic12f675 Microcontroller 8-PIN PONG

This project is based on ideas from Rickard's electronic projects page and David B. Thomas VCR Pong. However, I have developed the simplicity even further, eliminating most of the external components. Using microcontrollers with internal 4MHz clock generator there is no need for the xtal. The 12f675 part also operates on wide voltage range, and the regulator can be removed. For game controller, I plan on us ...

12 DIGIT RUNNING SIGN using PIC16F628

It's 1970 and a 12 digit LED Display for pocket calculators has just been released. Nation Semiconductors are in the forefront of designing miniature displays for calculators and have a range from 2-digit to 16-digit displays. The actual 7-segment displays are so small it takes a bubble magnifier in front of the LEDs to see the digits. We have used one of these in this project. Fast forward to 2011. These d ...

PicChess

This project is a micro controller chess game. The objective has to be able to play chess on a VGA monitor, including an intelligent computer to play against. This all has been accomplished with a microcontroller. I started this as a project for the college ( I am a Electrical Engineering student ), but it has grow way beyond that. Now it is a complete chess game with a video output, keyboard for user inter ...

Fun with PCBs

Last year I bought this Etch-Set For Electronic Circuits from Jaycar with the intention of having a go at making my own printed circuit boards (PCBs). I’d had lots of experience working with those experimenter’s Stripboards and Perfboards, which had been more than sufficient for most of the fiddling I did in the past, however I was always intrigued by the idea of rolling my own PCBs although I lacked the re ...

One Chip Video Poker using PIC16F628 microcontroller

This is a simple video poker game for the PIC 16F628 and a 20x4 character LCD. It's written in PIC assembly for MPASM. I started the project in 2002. I originally intended it as a birthday present for my brother, who is an enthusiastic if occasional player of casino video poker. This Mark I version foundered, though, as the PIC 16F84 didn't have quite enough program ROM to handle it; I shelved the project u ...

Virtual Tetris

Introduction The idea to my mechanically scanned game system came from Bob Blick's mechanically scanned clock, so I thought that I also had to implement a clock on my virtual game system. The clock can simulate both a digital and an analog clock. Due to that the resolution of the clock is only 24x16 pixels, it is hard to show the time in both cases. In the case of the digital clock, scrolling the time over ...

Virtual Tetris

Introduction Tetris is a very simple, but elegant game. Blocks of four bricks each are falling down in a play field, and the player can rotate and move the block sideways. When the block hits ground or another block below, it stays there. If one line of bricks is full, then that line is removed. As the game is running, the falling speed increases. The goal of the game is to keep playing as long as possible, ...

Virtual Pong.

Introduction The game Pong was the world's first video game in the early 70's, it is a tennis lookalike game where a ball is played with two rackets, which are moved up and down by each player. The ball can bounce at the floor and the ceiling. This version is implemented with the virtual game system It was the first game I made for the system. Features Some special features of the game is that it is possibl ...

Virtual Game System – A game console with a mechanically scanned display.

Introduction If you move a bright light fast by the eyes, it will leave a line behind because the human brain and eyes are slow to interpret fast changes in light intensity, leaving an afterglow. If a row of LED’s is moved sideways while the LED’s intensity is changed, an image will shortly visualize in the air where the LED’s are moved. If this is done several times, for example if the LED’s are mounted on ...
