LaserCut Input Devices

Description of the project

The exercises for this week seeking to be implemented in my final project, which will use stepper motors to move the general mechanism.
A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.

"Input Device"

    For my project input my challenge was to create my personal Arduino, now with the name of F_Duino So as you can see my F_Duino is based in the FabKit but with some changes in the microprocessor, using the ATMEGA88 Voltage Regulator and adding one for the power supply. The first thing I do is program my board from Arduino and using my FabISP in-circuit programmer. Once I make the programming process, as I show in the pictures, I make a blink test to verify that receives information seamlessly. The exercise this week is to connect a potentiometer to my F_Duino and power it through the code attached, and the main goal is to mone a stepper motor while you move the potentiometer, to be able to control movements accurately.
