Hello propel, and tanks for taking time to lend me your ears.
I am looking for advice regarding what parts I need to order, in order to realize my project.
In short, I want to make a board that controls 4 small disc vibrators, and accepts input in a "wack a mole" type of way.
So if disc 1 vibrates, then disc 3, it would then pause and wait for input from contact 1 and then 3, and then if the sequence is correct, play a little sound.
Ideally I would like to setup an array of possible sequences to be randomly selected, and maybe have some sort of output to be able to process the it remotely
I'm thinking I need the 4 motors, 4 contacts and a basic r3 board maybe? Can anyone help with some input?
You can't drive motors directly from an Arduino. If you just want one-direction control you can probably use a transistor (1 for each motor) to allow the Arduino signals to control the power to the motors.
Robin2:
An Uno should be easily able to do what you want.
But a Nano would be more practical for an assembled project.
A TPIC6B595 would drive up to 8 small motors up to a few hundred mA. Check out how much current is required for these disc vibrators. (I can't find mine in a hurry, but did come across them recently while searching.)
