// With this program, you can use the ESP32 as an ultra-low cost signal generator.
// To learn more, see https://techexplorations.com/courses/oscilloscopes/

#include <Arduino.h>

int i = 0;
int sample_delay = 0;
const byte POT_GPIO = 35; // Potentiometer
int   t_sample;

## 07_PWM.ino
/*  07. Arduino PWM oscilloscope demo sketch
 *
 * Use this sketch to experiment with the measurement of a PWM waveform
 * on an oscilloscope.
 *
 * Connect CHA of the oscilloscope to the anode of the LED.
 *
 * Use a potentiometer to control the duty cycle.
 *
 * Set triggering to Auto, and start the experiment.

## 05_button_reaction.ino
/*  05. Arduino button oscilloscope demo sketch
 *
 * Use this sketch to see a button press as a waveform event in the
 * oscilloscope.
 *
 * Connect CHA of the oscilloscope to the button signal pin.
 *
 * Connect CHB to the anode of an LED.
 *
 * Set the scope to 5us time scale and 200mV voltage scale.

## 06_distance_sensor.ino
/*  06. Ultrasonic distance sensor HC-SR04 demo sketch
 *
 * This sketch calculates the distance between the HC-SR04 sensor and
 * an object directly infront of it.
 *
 * To see the trigger and echo waveforms with your oscilloscope,
 * connect CHA to the trigger and CHB to the echo pins.
 *
 * Set up edge trigger to CHA, and set it to 1V (or there about).
