Hello fellow circuit people,
First off, im an absolute beginner in electronics. Also English is not my mothertongue, so if you don't get what im trying to say thats probably the reason.
Im trying to find a way to make a miniature swing. I could just power my motor in one direction with a pulse every few seconds, but it would be better and more consistent if the motor's polarity just switched every few seconds.Also I would like to learn and find out if my theory is possible at all. I have tried some easy circuits using a led light with the 555 ic, but I get stuck at the same point every time. because the circuit resulted in a blinking light, I thought I could get my motor to switch on and off at the same pace as the led. If this was the case I could just hook a dpdt relay on that led output and cross wire connect my motor to it for the reversed polarity. Now I discovered that the power input for the relay was 6V, so the output I got for the led was not strong enough to power the relay and so it didn't switch. I bought a step up module to increase the power for the relay but im starting to think that there is probably an easier way to do this. I wanted to connect a potentiometer to contol the amount of time that the motor's polarity would switch, and the duration of the pulse that the motor would get.
So my actual question is: How can I make a circuit, that reverses the polarity that powers the motor, at fixed time rates (preferably controlable) while the only action required is turning it on. I would like to use 4 AA batteries, a dc motor, a 555 ic, a dpdt relay, a step up, and various types of resistors, transistors and capacitors. Without Arduino.
Thanks in advance!
