Worked on the tactile keypad and made a library.The library contains a function that returns the number of the switch that was pressed. Using this the user can give an input. We still had problems with PID values. With the same constants and circuit we used the previous day, it took an unusually long settling time. We the changed the resistance values and adjusted the constants to get a better response.
Later we found that the input was getting attenuated, and there was a significant drop across the resistance of the RC filter even when we gave a DC input. We changed the location of the filter on the breadboard and the problem was fixed.
