Double face board with an Atmega 328P, The board is designed to control the outputs of the Heliotropo the input ( a phototransistor and a light color sensor in the upgrade version that I couldn't finish yet.
Sensor board (Right now)
3d print connections and special parts
The main structure has been design and made with acrylic of 4mm.
Here is the code to make boards work together.
This is the code for the Helioduino board, prepared tu control de NEOPIXEL LEDs and the STEPPER, it includes the serial for networking with the other board.
Here is the code for the phototransistor to comunicate with the Helioduino board
BOM (Bill of Materials)
The total cost was around 110€, but it's that I had to spend more money in the previous prototypes also there are some parts that can't be buy individually. Here is the complete BOM
This project it's an individual effort but it could not be possible without the invaluable help, advice and knowledge of...
Marta Verde, our instructor and, at this point, friend who has been in the lab more hours and answer to whatsup much more that we deserve
Juan Fuentes and Luis Fernández, the fablab stuff. Than you for their patience and compresion with our disorder and late hours at the lab.
Beltran García, my little brother and partner, he sold more copper rods that i'm willing to accept and let me sleep in his couch when I was too tired to go home.
Ignacio Prieto and Dani García, the bosses. The let us take any tool from here and seat with us to show us the tricks of 3d printing electronics and many more things.
And of course to my classmates and partners Rodrigo Gamboa and Edu Segovia in the machine assignment. Many afternoons where working and learning together, this experience would be very different without you.
