Question a) to g) are based on the following Arduino Uno figure. B E A D4 F 9000 9A5 ४ DIGITAL (PWM-) E O UNO ARDUINO NOVES HERMAN POWER O www.ARDUINO.CC MADE IN ITALY JK L ON 8 G ANALOG ICSP H Input methods a) [2] Arduino can read analog signals through its pins. In the above figure of Arduino Uno, which pins can be used to read analog signals? Indicate all letter(s) representing these pins! b) [2] Without any data processing, what is the maximum level of analog signal that can be properly read by the pins in question 1a)? (Answer in voltage) c) [2] The Analog to Digital Converter in Arduino Uno system has a number of quantization levels. How many levels are there? d) [2] If we feed one of the pins in question la) with P volt, what level does the arduino read? (Answer in integer number, not binary. 0.50 V < P < 4.50 V) [2] If we feed one of the pins in question 1a) with an analog signal and the Arduino reads a level of Q. What is the voltage of the analog signal? (Answer in V, 2 decimals, 100 < Q < 1000) e) Output methods A PWM signal is controlled by pin 5 with a duty cycle of R %. (20% <R < 80%) f) [2] How long the signal is in a "High" state? (Answer in us with 2 decimal points) g) [2] If pin 5 is controlled by using analogWrite (5, pwm), determine the value of pwm (an integer) in order to generate a duty cycle of R%? Question h) to j) are based on the following figure. 0000000000000 3210980 7654 Arduino EV 235665 012345 OOOOOO 000000 5 2 M 3 +V Gnd h) [2] If pin 3 is "high" and the motor M is running, determine the direction of current flow by using the node numbers (1 to 5)! For example, the number 41 indicates current flowing through the diode (forward current) and capacitor. i) [2] From condition in question h), if pin 3 is suddenly turned off then there is still some current flowing in the circuit. Determine the direction of this current flow! j) [2] Explain the kind of problem that may arise from driving motor in Arduino and the way to solve it!
