| 説明 | I finally got round to finishing my radio alarm clock project. Most of the parts were reclaimed from old scrap electronics. It uses a repaired scrap transistor radio, and a >>very<< old RS 5volt 1amp encapsulated power supply. The speaker was liberated from a scrap television. I purchased the LCD screen and the ATmega for a song and wrote a program to connect everything together. The 6 micro-switches on the front allow the time/date and alarm time to be set. Toggle switches on the left of the picture function as volume control, LCD light on/off, mute/reset etc. It uses a crystal/frequency divider to keep the time accurate. |
