Aurora 9×18 is a beautiful firing sequence of 162 RGB-LEDs in a circular configuration. The color of each circle is controlled by a microcontroller (PIC24F08KA101) using a twisted form of PWM. The MCU only has one PWM module, yet Aurora is capable of 27 (9xR,G,B) independent brightness control.
Smoke-O-Tron is PID controller for electric smoker temperature developed based on PICAXE microcontroller. The controller can handle the 1500W heater to within about 3 degrees F. It will measure temperature in the space and switching the heater on and off at a given speed.
This project shows you how to connect inexpensive calipers, micrometers and height gauges to PC through serial RS-232 interface and see the result using PC software. Its main part consists of minimal PIC to RS-232 interface, +5V/-1.5V power from serial port, and 1.5V to 5V logic level conversion. “The connector on the measuring instrument will [...]
This project allows you to read many common EPROM and Flash memory chips. It’s equipped with USB interface that uses FTDI USB to serial chip. The PIC18F4550 microcontroller firmware handles the various differences of the range of EPROM chips. The project only uses HyperTerminal PC software to control and read the chips. Intel hex and [...]
