OK, here's the direct answers to your questions
Ugive U2 4 volts through a voltage divider.
No, you're not doing that, and in any case the 555 requires a minimum of 4.5V. As mentioned above, remove the 1 ohm and 560 ohm resistor in parallel.
Use a H bridge rather than a DPDT relay.
You've done that, but you've not placed any base resistors in the circuit.
A problem with driving this is that the 555 can't pull the output high enough to turn the top transistors properly. You could consider replacing them with PNP transistors, but then you may have problems turning them off!
The relay may be your best solution here.
This might be off topic but the whole concept of ground confuses me. In a real life DC
circuit what is ground. Does this device even need ground?
Sorry, I don't understand what you're saying.
The negative rail is usually labelled ground, but that is because it is a reference point for voltage measurements, you don't earth it or anything like that in most cases.
Say I wanted to add some more features, I could add more 555 timers but using a micro controller sounds easier to use. One problem, I have no clue how to program. Is this a hard skill to develop or is it the way to go? I am willing to learn though
A microcontroller is definitely more flexible, and as you correctly deduce, more complex as well.
There are several microcontrollers which are good for beginners. In all cases you'd probably want to get to know the microcontroller before you start a project for real. Look at PicAxe and Arduino, although there are many other options.
I agree, a n channel mosfet is the way to go.
How should i have wired Q1?
Q1, do you mean M1?
That's OK, except that you need a P channel mosfet. However you have the source, drain, and gate in the correct places. A gate resistor (of about 100 ohms) would be nice to have.
In my H bridge do I need to use MOSFET's? OR PNP?
I'd probably use logic level mosfets because you're operating from a low voltage and bipolar transistors may drop more voltage (that your motor may need)
My motor draws about 60 ma plus or minus 3.
Good, that's not too much.
However you will require diodes to protect the H bridge from transients. This is another reason why a relay may be easier for you.
If you havent already noticed I'm new to this stuff. Thanks for everyones time and MERRY CHRISTMAS
No problems. Merry Christmas!
