In fact, feeding, feeding various timing circuits used for business. Generally puzzling, time-consuming mechanical parts is getting no special circuitry to rabbits in this project but the authors have used to feed rabbits 🙂 crafted with a software pascal Pascal example might be for users.
Circuit based on Atmel ATmega 8 2 × 16 LCD also displays information on the source code of the circuit prepared with eagle pcb, diagram drawing there.
The program basically consists of a real-time clock and a PPM signal generator to drive a servo motor. The servo motor, which rotates an eccentric shaft (small hooks), places it in precise angular positions. Each angular position releases a dose of tilt
Four buttons are used to set the clock (plus and minus hours, plus and minus minutes). A button allows you to manually advance the angular positions cycle to set the mechanics and reset everything at startup. The 2×16 LCD display shows the day, time, mode (manual, automatic). The on-site programming connector makes it very easy to change the software.
The trigger times (06:00 and 18:00) can be changed in the program, but not in “live”; I have no problem with that. The merit of this success lies in the program: it is written directly in PASCAL.
