9. DIGITAL SWITCH Inputs
The digital inputs on the Isaac16 EDU Robot Controller can be used to monitor various conditions on
the robot and trigger automatic responses by the control (PBASIC) program. The Isaac16 EDU
Motherboard has eight 2-pin DIGITAL SWITCH connectors (abbreviated SW). Pre-wired switches are
available from Innovation First. Various switches may be connected to the digital inputs.
Connect switches between the desired digital input signal pin and the ground pin only. Digital inputs are
“looking” only for ground signals to become active. Do not connect positive voltage to any switch or
digital input pin, only ground. Switches may be wired individually, in parallel, or in series. The
SWITCH pin headers are typically wired using 2-wire extension cables.
