I am trying to build a circuit that will power a small 1A DC motor for 0.5-15s. I found a diagram in this forum and built it without a problem. It works great when I only test it with an LED.
When I attach a motor, things go haywire. The problem is that the diagram I have includes two separate sources. 1 source for the 555 timer circuit and another separate source for the motor.
Because this is part of a science olympiad competition, I am bound by the rules to have only 4 x 1.5V batteries. Is there a way to split the 4x1.5V source into two isolated circuits? Is there a way to keep the motor noise/back emf from disrupting the 555 timer?
I could power the motor with 2 x 1.5V. Will the 555 run on 3V?
