Hi, can any one help? I,m just teaching myself basic electronics and have built a hobby kit (9V) using a 555 timer to tigger a LED off/on over various lengths of time. Have run a lead from pin 3 of 555 timer IC to base of transistor (548) to trigger 9v electric motor without success,I have also tried using a 9v relay but again not enough power to drive electric motor. My aim is to set up various tigger switchers with timming cicuits to drive different toys and lights to help stimulate learning for a child with intellectual dissabilities. If any one could offer some advise and/or some easy to read circuit diagram's in this area it would be greatly appreciated.
Thankyou
