Analog Clock

This is a small example of an analog clock based on a TinyRTC (DS1307) for LPC1768 and LPC1114. The clock is displayed on a small (96x96) Sharp Memory LCD. http://www.adafruit.com/products/1393 The TinyRTC is something like that (a simple DS1307 with some capacitors and a crystal does the job too): http://www.amazon.com/SainSmart-DS1307-AT24C32-memory-Arduino/dp/B00E37VTWY The RTC-lib created by Henry Leinen is used and the algorithm for calculation the clock-hands is based on input from http://arduino-project.net. /media/uploads/worstcase_ffm/analog_clock.png
