For this week assignment we had to make an output device, the knowledge of this week is important for my final project because I am thinking on using a Servo motor to trigger my catapult. During my review with Jake he mentioned Servo motors and their uses, wich I think are amazing.
I started changing some parts on the board that was on the webpage, I got to mill it correctly and it came out really clean.
I had some trouble picking the right components in the shop as everything was kind of messy but finally with the help of Jiri I could pick every single component succesfully.
I solder everything succesfully, the attiny was kind of tricky but with some patience and good music I could do it succesfully.
turned out pretty clean.
Time for the real stuff

While programming and connecting it to an external power source of 5V I first used the one available in the MarsLab, the board started gaining a lot of heat so then I decided to try with a battery and I got the same result.
Turns out there were no 22uF capacitors in the electronics room and I thought I could manage with a 10uF. After taking a look at a lot of past years webpages I found that most people had encountered the same problem with this same board, I then saw how you can stack the Capacitors vertically and it would do the trick so I decided to try it.

After this I tried to program and the heat kept on coming. I looked at other student's webpage and will try to make some of their boards and then make mine again, I had made an appointment with Teja also to try to learn more about what happened as this week is important for my final project.

Tough week...

Update



As this part is important for my final I decided to keep on trying, I milled and soldered the chip for a DC motor and after several attempts and error-1s I succesfully programed the board.



I connected it to a 9v battery and then connected the motor to the 2x3 header using the male female connectors, sadly the motor didnt move at all so I am now trying to understand what did I miss so that I can play with the C file now.



Alfonso from CBA recomended trying with stepper motors also so I milled and soldered another board so I caould try both motors.
I will try to make both motors work and do some more research in order to understand which motor is the best fit for my final.
