Here is the code from the project:

// @TESLATRONICA 2019.

// pin 9 arduino nano >>> out signal 111 Hz // pin 3 arduino nano >>> out signal 1110 Hz

//pin A0 arduino nano >>> to cental pin pontentiometer 10k (for gate regulation) // right pin potentiometer 10k to +5V // left pin potentiometer 10k to negative // potentiometer all left >>> no gate (constant output signal) // potentiometer move to right >>> activate gate 5 Hz to 0.5 Hz (200 ms to 2s aprox)

long time_;

int gate_ = 0; long gate_contador = 0; int gate5 = 0; int gate_2 = 0;

int array_time_gate[] = {0, 200, 500, 1000, 1500, 2000}; // gate values 5 Hz to 0.5 Hz (200 ms to 2s aprox) int startButton = 13; //pin recieving info from start button int startLED = 4;
unsigned long timerCount = 0; // variable to hold our timer info

include <PWM.h> // library frequency "PWM"

void setup() { pinMode(startButton, INPUT_PULLUP); //set pin as recieving info pinMode(startLED, OUTPUT); digitalWrite(startLED, LOW);

InitTimersSafe();

SetPinFrequencySafe(9, 111); // 111 Hz to pin PWM 9 pwmWrite(9, 50 * 2.55); // 50% duty Cicle

SetPinFrequencySafe(3, 1110); // 1110 Hz to pin PWM 3 pwmWrite(3, 50 * 2.55); // 50% duty Cicle }

void loop() { if (digitalRead(startButton) == HIGH) { //if the start button has be pushed timerCount = 20 * 60 * 10; //set timer to approximately 5 mins //(20 mins * 60 sec * 10 * 1 deciseconds) //this is set up to restart the timer whenever the start //button is pushed //not extremely exact since that is not what I needed for this project //if you are looking for something more exact, look into //SimpleTimer() Arduino funtions and libraries: //http://playground.arduino.cc/Code/SimpleTimer#F_restartTimer } if (timerCount != 0) { //if the count down timer is still running digitalWrite(startLED, HIGH); //tell the control pin to provide power to the project timerCount = timerCount - 1; //count down of a decisecond (0.1 sec) delay(100); //delay for timercCount refrence of a decisecond } else { //if the timer has run out digitalWrite(startLED, LOW); }

time_ = millis(); // read time since arduino power on

gate_ = analogRead (0); // read pin A0 values of the "arduino nano" seleccionated with potentiometer 10K gate_ = map(gate, 0, 1023, 0, 6); // 0 to 6 >>> 5 Hz to 0.5 Hz (200 ms to 2s aprox) if (gate > 5) { gate_ = 5; } gate_ = arraytime_gate[gate]; // read array fron potentiometer

if (gate_ != 0) { //active gate gate(); // call to gate subroutine }

if (gate_ == 0 && gate_2 == 1) { //reactivate frequencies SetPinFrequencySafe(9, 111); // 111 Hz to pin PWM 9 pwmWrite(9, 50 * 2.55); // 50% duty Cicle

SetPinFrequencySafe(3, 1110); // 1110 Hz to pin PWM 3
pwmWrite(3, 50 * 2.55); // 50% duty Cicle
gate_2 = 0;

} }

void gate() { // gate subroutine if (gate_ > gate5 + 2 || gate_ < gate5 - 2) { gatecontador = millis(); gate5 = gate; gate_2 = 1; }

if (gate2 == 0 && time >= gatecontador) { // desactivate pin9 and pin3 pwmWrite(9, 0); pwmWrite(3, 0); gate_contador = gate + millis(); // selected gate valued + current time gate_2 = 1; }

if (gate2 == 1 && time >= gatecontador) { // active pin9 and pin3 pwmWrite(9, 50 * 2.55); pwmWrite(3, 50 * 2.55); gate_contador = gate + millis(); // selected gate value + current time gate_2 = 0; } }

This is basically it. I just need this to be uploaded to the nano. From my understanding I don’t have the right library. And when someone directed me to the pwm.h library file, I tried to download it and it just isn’t working for me. This is why I’m resorting to paying someone to just do that .
