Hi, I was hoping I could get some assistance from someone on a halloween project I was doing. I am trying to make a simple circuit to move a spider 4ft up and down a wall. I have made a dead simple circuit using a relay and two microswitches that simply reverses the polarity to the motor to make the spider move up and down.
This however requires the microswitches to be pushed as the spider reaches the correct position, still simple but I prefer neatness! So I was thinking a timing circuit with the 555 timer could energise the relay then de-energise it. However i'm unsure how to do this properly. I want the motor to run for probably about 5-10secs each way on a constant up and down motion i.e. no stopping.
Would I use two timing circuits? e.g. one to firstly energise the relay then the other to reset the original timing circuit? Does this work?
Sorry if the answer is easy but im lost!
