1. Write an Arduino sketch to perform the following: Repeatedly apply 5 V to your output pin and hold it for a period of 10t, then apply 0 V and hold for 10t. Read the input voltage Vin and the measured voltage Vc at time intervals of 1/50. Send these readings, separated by a comma, to the serial port at a baud rate of 9600 bps. Leave the readings as they are there is no need to convert them to voltages now. Check that your program works by opening the serial monitor. 2. Modify the Arduino sketch (save it under a new name) to perform the following: When the code begins, hold the voltage at 0 V for 5 seconds to fully discharge the capacitor. This should be done in setup (). You do not need to output data from the setup function. After this (in the loop section), cycle the voltage quickly. Apply each voltage for 100 msec (instead of 10t). Collect data at the same rate as in step 1 and send the values to the serial port.
