About this project

I needed an oscilloscope to test some relay boards but I didn't have one and I didn't want to spend $40.00 to get one, so I decided to make one that was very simple but looked nice.

Code

Oscilliscope codeArduino
all you have to do is upload
RSP is the creator initials
v1. is the version
the numbers after v1. is how many seconds you have been recording
running is the status
// Included Libraries
#include <LiquidCrystal.h>
// Pin Definitions
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

void setup() {
  // put your setup code here, to run once:
 Serial.begin(115200);     //Setup seriaal connection
  lcd.begin(16, 2);
  lcd.print("OSCILLISCOPE RSP");
}

void loop() {
  // put your main code here, to run repeatedly:
 lcd.setCursor(0, 1);
  lcd.print("RUNNING v1.");
 lcd.setCursor(11, 1);
  lcd.print(millis() / 1000);

   int val = analogRead(A0);
   Serial.println(val);
}
