The structure of the interrupt routines for handling the encoders are included below. To test the encoders and the code, a program that displays the encoder's position value every 0.1 seconds is to be written. Functions Needed: attachInterrupt( Interrupt, ISR, mode );Program Structure:Global Variable encoderPosition// Interrupt service routines. void MonitorA()if input A and input B are equal // input A and input B are pins 2 and 3 respectively. Increment encoderPosition. elseDecrement encoderPosition. void MonitorB()if input A and input B are equalDecrement encoderPosition. // Note this is the opposite of what happens above!elseIncrement encoderPosition. SetUp:Attach MonitorA to interrupt 0, (Pin 2) and set mode for any change. Attach MonitorB to interrupt 1, (Pin 3) and set mode for any change. Loop:Every 100 milliseconds display encoderPosition on LCD screen. Write the program described in the program section.
