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.
The project shows you how to add a USB interface to a standard HD44780 compatible LCD and emulates the CrystalFontz serial protocol over a virtual COM port created by the FTDI chip. This enables you to use already existing software to speak to the LCD, for example the popular program LCD Smartie. The circuit [...]
LCD Smartie is software for Windows that you can use to show lots of different types of information on your LCD/VFD. It supports LCD/VFD’s with a Hitachi HD44780 Controller, a Matrix Orbital Serial/USB LCD, Crystalfontz Serial/USB LCD, Seetron Serial LCD/VFD, IRTrans driven VFDs, SoundGraph iMON VFDs, Futaba VFDs, Pertelian LCDs, VL System L.I.S VFDs, IEE [...]
This PIC16F628-based compass uses NMEA-0183 data from a GPS receiver. The direction indicator displayed on eight-point LED with radial pattern every 45°. Although the GPS provides accuracy to a tenth of a degree, that kind of accuracy is not really necessary in the automotive use for which project is designed.
