what i tried after my software was failing after around 30 mins + .
i was using a standard 7805 regulater ic powered from
a 500ma transformer + full wave diode rectifier.
i later removed input from AC to regulater and connected a battery 12v 7AH to input of 7805. Now with
battery the software works without any problem for hrs
together. What could be wrong with my power supply? as now that i have confirmed that the powersupply was doing all the mischief. now that i cannot use battery pemanently what steps should i take ???
