All In One Clock

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

Components

• Arduino UNO
• Arduino Proto Shield
• Real Time Clock
• 16x2 Display
• Tactile Switch
• Buzzer
• Breadboard
• Wires
• AM2302 DHT22

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.

Upload The Code

Open your arduino ide and upload clock_alarm.ino

make sure to downlod these libraries first

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

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
