Story

In this project we will make an arduino clock alarm with timer and a temperature sensor.

Wiring:

Button #1 Mode - connected to digtal pin 2

Button #2 Select - connected to digtal pin 4

Button #3 Plus - connected to digtal pin 3

Button #4 Minus - connected to digtal pin 12

Button #5 Timer on/0ff - connected to digtal pin 11

You can wire all of the component to a breadboard or wire to a arduino proto shield if you would like to use the case.

libraries:

DHT - https://github.com/adafruit/DHT-sensor-library

LiquidCrystal I2C - https://www.arduinolibraries.info/libraries/liquid-crystal-i2-c

Wire - https://github.com/arduino/ArduinoCore-avr/tree/master/libraries/Wire

virtuabotixRTC - https://github.com/chrisfryer78/ArduinoRTClibrary

RTCLib - https://github.com/adafruit/RTClib

Usage:

Change between screens by pressing mode button

Set time by holding mode button in screen 1

Screen 1 - time date and temprature

Screen 2 - set up the alarm

Screen 3 - timer

Screen 4 - alarm On/off
