PING SENSOR ACTIVATION

I have a mobile robot which I want to send tirough a maze and I$\text{'}$m going to use at least

$3$ ping sensors and an Arduino to help me guide it$.$ What sort of code should I write so

that they can steer me through? Bonus #$1-$ How would I hook up the ping sensors$?$

Bonus #$2-$ How would I code for the motors? Bonus #$3-$ How would I hook up motors?

$($I know you could spend a LOT of time on this. Can simply show me some sample code

and explain how you would modify it$)$
