Alarm Clock
Hey everyone! In this Instructable, I will be showing how to create a simple alarm clock (In Tinkercad). It shows the normal time, and you can change that as well. The alarm part works similarly as in you can choose when to set the alarm as well. When the alarm goes off, a Buzzer as well as an LED will go off. Let's begin!
Supplies
1. Arduino UNO
2. Breadboard
3. LCD 16*2
4. LEDs
5. Resistor
6. Jumper wire
7. Push Buttons
8. Buzzer
9. Potentiometer
Wiring
Here is all of the wiring that you have to do
To control the clock, there are 3 buttons and 1 switch.
The first button, the one on the left, controls the hour part of the clock
The second controls the minutes
And the switch on the right switches between the regular clock and the alarm settings.
Coding
Here is a text file for the code:
