You are writing an Arduino sketch that displays the voltage at the potentiometer using a function that reads the value from the potentiometer through analog pin Al. The function read_avg_sensor_val" takes two inputs, "int val" and "int num". "int val" is the value read from the potentiometer, and "int num" is the number of samples it averages. Each sample will be read every 10 ms. Complete the function shown below. (30 points) Note: The values read by Al needs to be converted into voltages in the function. 3. o22 int pinVoltage A1; void setup) Serial.begin(9600); For Loo? void loop() Doure int potVal; potVoltage read_avg_sensor_val(pinVoltage, numVal; Serial.print("Volatge detected - "); Serial.printlin(potVoltage); 5 Palum float read_avg_sensor_val(int vat, int num)
