1. Complete the code in a way that LED blinks every 2 seconds. 2. Change the startTimer method to accept a double value called timerFrequency, which represents the frequency of the timer. Change the startTimer function so that it uses the value of this parameter to calculate and set the correct values for the OCRX and TCCRX registers. 3. Use the potentiometer sensor connect to pin A4 to enable users to configure the timer frequency. const byte LED_PIN = 13; const byte METER_PIN = A4; void setup() pinMode(LED_PIN, OUTPUT); pinMode(METER_PIN, INPUT); Serial.begin(9600); startTimer(); void loop() void startTimer() nolnterrupts(); interrupts(); ISR(TIMER1_COMPA_vect){ digitalWrite(LED_PIN, digitalRead(LED_PIN) ^ 1);
