We're ringing the bell!
Overview
Let's do something fun with our IotBot! We will make a system that shows which bell is ringing on the LCD screen when the encoder button or digital button is pressed.
We will do it like this: The encoder button connected to pin 13 will be the bell of the first floor, and the digital button connected to pin 0 will be the bell of the second floor. It will show us which one is pressed on the screen. Also, when these buttons are pressed, the LEDs on pins 25, 26, 27, 32, 33 will give feedback with different lights.
How exciting, right? Let's get started and make a great app full of bell sounds!
