hey all
i made a logic circuit contain
cmos 4011,4071,4009,4010 ics
3 transistors bd139
buzzer ans 2 motors 1.5 v (motors which in toys)
and the battery is 9v across regulation with 5v
the problem : when i running the circuit , the power consumption of the battery is very high
and the battery is down from 9v to 7 in 2 second after running the circuit
how to solve this problem and what is the source of the problem?
thanks in advance
