Pong is known to be one of the earliest arcade video games. There are already a lot of DIY versions of this classic game available on internet. Jacques from Quebec was successful to squeeze the pong program into Microchip PIC10LF322, which is one of the tiniest microcontrollers. His circuit operates at 3 to 3.6 volt power supply and generates NTSC video signal to connect to a TV.

LED matrix displays provide flexibility to display text, graphics, animations, and video, and therefore, they have become a popular mean of displaying information these days. You can see them at gas stations displaying the gas prices, or in the public places displaying information, and alongside highways displaying advertisements on large dot matrix panels. This project is about constructing a mono-color LED matrix display board that consists 320 LEDs arranged in 8 rows and 40 columns. The heart of this project is PIC16F1847 microcontroller which receives data from a PC through a serial port (or USB using an USB-UART interface), and

Mark Weir from Australia sent us his revision of our Programmable digital timer switch project. He modified the original code, which was written for PIC16F628A, to incorporate it with PIC18F4620 microcontroller, while hardware and overall functionality remain the same. Here is a link to download his modified version of the firmware written in MikroC compiler. Download Firmware

TrH Meter is a DIY digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor (LDR) and uses that information to adjust the brightness of the display. An inexpensive DHT11 sensor is used to measure temperature and relative humidity. You can buy a complete TrH Meter kit with a preprogrammed PIC microcontroller for $26.00. Tindie buying link for TrH Meter kit.
