hi.. am having an old Refrigerator. Itz continuously working , causes heavy current charge i wish to construct a timer circuitry for cut off the above device am using 8051 micro controller .. I wish to use P1.7 as energizing pin.
i wish to give half an hour cut off after every 2 hours of operation.
so.. help me to create the code .. thanks..
It's definitely no good for a refrigerator work intermittently. The compressor is fragile to the accumulating shocks.
Check seals. A refrigerator would continue to work when seal fails and heat leak in. Check temperature feed-back loops. When such loops fail, a refrigerator would continue to work until everything freezes.
And a better solution is to replace the antique refrigerator with a new, green one.
Errr - but that's exactly how a traditional (electro-mechanical) thermostat works!!

Exactly - it's just that many new fridges are so quiet that people don't hear when the compressor starts/stops.
