This project is a four in a row game using a PIC microchip 18F252 controller. You can play against one of your friends, while the PIC keeps track of games won and who’s turn it is. The device uses 43 two color 10 mm leds.

This is a very simple low-cost logic analyser using the PIC18F252 of PIC18F2525 as capture device and a windows based PC for display. In Normal mode the max sample rate is 2 microseconds although the sustained rate is limited to 170 microseconds/event (RS232) of 40 microseconds/event (USB).In Fast mode the max sample rate is 200 nanoseconds, 4bit sampling is supported at 500nsec and lower rates.
