hello everyone.ive been working on a project for awhile, and im so close to completionexception for one little problem. im trying to power a small DC motor,as well as about 20 3mm LEDs, but am running into timing issues whenthe pump is powered.the circuit is:a 555 timer, whose frequency is around 30Hz; most of the time theoutput is +, when it is - its only for an extremely short amount oftime (its a strobe light, basically). the output of this timer goes to20 parallel 3mm LEDs to positive (no resistor, since theyre not on forlong enough to burn). just to be clear, to output of the 555 is:++++++++++-++++++++++- (at about 30Hz). when it's -, the LEDs go on.this works fine, until the second part of the project is introduced.id like to run a small battery powered water pump (it takes two 2x Cbatteries) but I'd like it to run on the power supply of theaformentioned circuit (4x AA batteries). im not quite sure how to dothis. the "pump" is just a small DC motor about an inch in diameter.i do not know the amperage rating of it.i wont even go over what i tried at the risk of sounding like a fool.whats the best way to run both the motor and the 555 timer + LEDs?thanks a ton,-sam
