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 uses […]
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.
