# Arduino Snippets

Library of useful C++ snippets and reusable classes I've created as I build out Arduino Uno and ESP32 projects.

## Button

A simple button utility that debounces and is meant to be triggered on `LOW` from a pin set to `INPUT_PULLUP`.

```cpp

// some data to send to action on press

int bData = ... 

 

void handleButton(void *data) {

  // Handle the button press

}

 

Button b(PIN, &bData, handleButton)

 

void loop() {

  b->test();

}

```

## Seven Segment

A utility for 4-digit seven segment displays using the TM1637 Drive Chip like [these](https://www.amazon.com/HiLetgo-Digital-Segment-Display-Arduino/dp/B01DKISMXK/ref=sr_1_1_sspa?dchild=1&keywords=tm1637&qid=1622991533&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExWUI0VUQ3OUFEMTUyJmVuY3J5cHRlZElkPUEwNTg2MzU4MTFQVjZCU0tTWTVVMiZlbmNyeXB0ZWRBZElkPUEwNTU2NTE3MjZJU042TldKOTM2RCZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=)

```cpp

#include "SevenSegment.h"

#define CLK 2

#define DIO 3

SevenSegment segment(CLK, DIO);

void onHalfSecond() {

  segment.clockPoint();

  

  // Set the hours and minutes from a clock source

  segment.setHours(clock.getHours());

  segment.setMinutes(clock.getMinutes());

  segment.update();

}

void setup() {

  segment.init();

  

  // Some kind of trigger on ever half-second

  // to flash the segment clock point

  // Timer1.initialize(500000); //timing for 500ms

  // Timer1.attachInterrupt(onHalfSecond);

}

void loop() {

  segment.loop();

}

```
