Pedal Board - Rev 3

edits to the original pedal board:

pedalboardanaloginputs.schdoc:

• removed the 2 potentiometer rc filters since they are no longer needed

  • left the opamp (u2b on the schematic) since they come in pairs

• added an rc filter for the hall effect sensor (just took the pot rc filter and changed it to hall)

• added a differential amplifier to amplify the 0.4-0.6V range from the hall rc filter to 0-2.5V

  • falstad simulation: https://www.falstad.com/circuit/circuitjs.html?ctz=CQAgjCAMB0l3BWcMBMcUHYMGZIA4UA2ATmIxABY8QkFIaBTAWjDACgAlcCikFFXthR8BUMRXoxekqNASduvFAkIghfFWPoTZCBNRkx5AJ0Uilo-tOTw2psDw2qrTsWHiQ2Ad3O+XYFANvP0s8ahdPHxdlZ00YqGD4pLDXTwBDPhSBbSo+HWowJBYkdw9JOULIBAxiQj0KB0hMXUqMEhRcNuIOiFLbU39AylyAg3A0Wx8eAqHpvMk2AAdh8J0VemzwLTYAc1dsbFjVbARhBYG4y+PDtwm4Nmwx8uloVQA1AHsAGwAXNJ2GA8ClpoC93t8-gC2EA

pedalboard.schdoc:

• changed the accelerator pedal connecter to a 4 pin connector

pedalboard - adc.schdoc:

• changed the input into the adc to the hall sensor differential amplifier output rather than 2 potentiometer rc filter outputs. left one floating
