Good Switch For Autonomous Mode Select

just wanted to share this info. On our robot for the past few years we have been using a SCSI drive select switch. It digitally selects the decimal values from 0-9, giving us 10 modes in autonomous.

They are inexpensive, and are good for teaching binary math as they wire into 4 digital I/O ports and then do bit math to get the decimal modes.

Here are some examples...

look for

SCSI ID Selector Switch (0-15) w/selector cable
$6.00

this one would do even more modes than 10 as I state above.

wiring instructions are here...

good luck...
