| - | TODO | + | The device that will remind the user of their tasks will need to connect to the server (meaning it requires network access) and will ping it at fixed time intervals to gain knowledge about upcoming events. A screen will provide the user with visual feedback, and, in case the user misses it, a buzzer will trigger as well. The reminder can be postponed (or silenced). |

| + | To accomplish this, I figured an ESP32 is best suited. | ||

| + | === Technology Used === | ||
| + | |||
| + | This is a **software-heavy** project! With this being said, I would like to point out the exact concepts I've used that were taught during this class: | ||
| + | |||
| + | - **GPIO** - the GPIO pins are used to enable communication between the IoT device and the end user; | ||
| + | - **Interrupts** - when pressing a button, an interrupt will occur; | ||
| + | - **Timers** - to notify the user before a certain task is due, timers are needed; they are also used to communicate with the server; | ||
| + | - **I2C** - the device's display is controlled via the I2C protocol; | ||
| + | - **ADC** - since you are eager to deduct points, I am required to make bad decisions regarding my project - in this case, the buttons will use fewer GPIO pins for no reason other than to use ADC. | ||

| + | <note warning> | ||
| + | Please note that this is a **software-heavy** project! | ||
| + | </note> | ||
| + | |||
| + | <note> | ||
| + | It is also worth noting that this is just a draft (and will remain a draft until the project is complete), since //"the calculation at home does not match the one in the market" 💀// | ||
| + | </note> | ||
| + | |||
| + | The server can be a repurposed old computer or, to simplify the process, a Raspberry Pi 4 Model B that I've had laying around :) | ||
| + | |||
| + | The IoT device will be an ESP32 module connected to a bunch of buttons, a small display and a buzzer. | ||
| + | |||
| + | === Bill of Materials === | ||
| + | |||
| + | * 1 x ESP32 module | ||
| + | * 1 x LCD display | ||
| + | * 1 x Buzzer | ||
| + | * ~4 x Buttons | ||
| + | |||
| + | As you can tell, there are plenty of external devices managed by the ESP32. | ||
