I have recently brought this Digital LED clock kit and after soldering it up i am trying to figure out how it works. I know how digital LED clocks usually work but i cant figure out how this one does specifically. It can run of the AC source (50HZ) or the oscillator, there is a trim capacitor to fine adjust the timing given from the oscillator. There is no counters or anything to gear down the 50 HZ frequency? But there is a pre programmed chip so is this where the frequency will be ramped down? Also unsure as to the parts that the transistors capacitors and resistors really due other than to provide the correct voltage for the rest of the circuit.
Ive attatched a picture of the circuit and the manual were the components can be seen.
Anybody fancy lending a helping hand?
Thanks
