This takes an extremely weak hall effect sensor output as input, amplifies it through an LM324 and passes it through an SN74LS14N Schmitt trigger to produce a clean digital pulse that can be read as a digital in to any small embedded processor. This board currently exposes two channels of I/O, but the amp IC and schmitt trigger IC both support 4 channels.
