Thank you to everyone that helped me with this. its short notice but I've fully finished the coursework and I am moving onto the next project. @Technoman @hippy @depeet especialy thank you and the community. I went with the 20x2 chips with 3 uln chips to control everything. I won't be able...

Due to it being a college project it can't be too complex as if too much work is put in they will remove marks so from what has currently been said its just a matter of me now making the circuit. poor cat

The college im at has the ability to create its own PCBs so it makes that risk null and void as any mistake is just lost baseboard. but you are correct as you don't want to have mistakes as in the past on projects I used a software called circuit wizard. because it doesnt have any linked company...

@hippy thanks mate I'm not fully at the programming stage as I'm just ordering all the electronics now. ill post the circuit once I have it done to do a final check then move to the programming. but it really helps with my understanding as I'm going to have to document all this development in...

I don't fully know how this is supposed to work but time to learn :D ive read this and it sorta does explain it http://www.circuitbasics.com/basics-uart-communication/ http://www.circuitbasics.com/basics-of-the-spi-communication-protocol from what i can see its a way for the inputs of one chip...

I found this joystick you can buy that I think works how you're describing. I did consider this approch however due to the accuracy that type creates it isnt nessay for the project and instead im going for more an arcade joystick design where it uses gates to control it. this will require for...

Sorry for the late comment to this been busy with other stuff, all the motors have arrived now so I can start doing the CAD model in regards to the architecture, I don't fully understand how you would program this as its not a strength of mine. I understand the master control 20m2 as it will...

yer sorry been a long day and just had a stupid moment and needed to think more about it before talking :3

this may seem stupid but by connecting to the 12 power rail will not cause a reverse signal into the chip or when the chip sends a signal does it sorta work like a transistor that will turn on the magnet or will it just get confused with 12v going in 2 directions. or is is just magic that it...

its not 6 anymore its 9 as i forgot to add 3 more as a way to set the motors home see #27 "yes i have and ive factored that into the new design i just drew up ( the new switches brings to total input to now 9" which is now why im going to use the 28x2 although i think it doesnt have enough...

So its a constant loop into the ULN rather than to 0?

ok thank you ill draw the circuit up when i can i have a meeting with the head of the course to start the write up

final question for the power regulator do i use a 5v regulator ( may seem stupid but not sure if im right in thinking that or do i need a 12v regulator)

im unsure how i would control 3 motors with 2 controllers as the guide material doesn't make it obvious how that would work or how i would programme that

yes i have and ive factored that into the new design i just drew up ( the new switches brings to total input to now 9), it was going to be a way for knowing when it had returned to home to know when to drop the prize. the electromagnet was going to be this...
