The following project was born with the idea that electronics is very easy to learn and modular at the same time. Although I have already finished my Fab Academy, I am still researching. Speaking with my instructors Nuria and Pablo, I told them that I wanted to continue working on the Hello World project, but I was not satisfied with making a board for each sensor or actuator.
So I decided to make a board with the ATtiny1614, where I could use the maximum pins for the inputs or outputs; that had external power; I2C connection. The idea is that a student can test as many sensors as possible, become familiar with electronics and programming little by little. And the Adrianino was born. Furthermore, I wanted to go one step further and place a VCC pin next to the UPDI programming pins, which I will explain later on how it works. This version of Adrianino has been updated for the new Serial-UPDI converter.

- This board has FTDI and UPDI + VCC connection to program it without the need for external power (or the FTDI).
- It contains a voltage regulator to power the board with a power supply (9V battery).
- It has another 9V power connection to for example power a DC motor driver.
- Then there are 4 outputs or inputs with VCC and GND on each side to be able to connect different inputs or outputs.
- On the left there is an I2C connection to connect an LCD, OLED or a sensor that uses this communication.
- There are 3 outputs or inputs at the bottom and with a GND pinout.
- There is an LED and an integrated button, which will help us to test that the microcontroller works with a simple program.
- Through the FTDI connection we can read the data from the different sensors through the Serial.”
