Input Devices
"The second half of the Fab Academy programme is designed to build on the previous weeks. You will be synthesising information and implementing skills that you were introduced to in the first half of the programme and encouraged to integrate these into your final project proposal. Measure something: add a sensor to a microcontroller board that you have designed and read it."
we were told to design an input design board so i can integrate it in my final project so i needed 2 pushbuttons to control my camera slider forwards and backwards so i designed it and made it and thought it was a valid thing for this assignment but it turned out that it isnt. in the Evaluation cycle my global evaluator made me realize that we had to measure something like sensor or other complex than a button but she made me realize this through her feedback on my assignment. so i didnt have the time to redo the whole assignment so i made a plan to do it in the future and impelement a light sensor to my camera slider so it can take a photo or do something when the light is turned on or something like that.
Designing the board
I wanted to make a board with 2 buttons as input so i can control the movement of my camera slider. So i designed a board consists of attinny45, resenator, 2 leds and 2 pushbutons in Eagle cad software.
First, i imoprted all the components to the workspace then i connected them together using net and wire tools. After that i switched to pcb design mode and started placing the components then routing the pcb traces and checking the DRC Rules.

Fapricating the board
After finishing the design i started fapricating the board i strted by cutting the traces then cutting the board then i started soldering everything together.

Programming the board
This week we were told to program the board we made earlier in week 6 assignment, So after searching i wanted to program it using arduino because i am good with arduino codes. So after searching i found HighLowTech Tutorial i followed every step in it and installed attiny files in my ide. After doing so i connected my board with my fabisp and burned the arduino bootloader for my attiny44a with external 20mhz resenator.
After burning the bootloader it is time for code so i wrote a simple arduino sketch that activate 2 leds and turns of the third when the button is pressed.
