The activity of this week is for interfacing an output device, in my case will use two stepper motor, which I made speed control from my application in APP INVENTOR.
Developed steps are:
STEP 1: Register in APP INVENTOR
I support this part of the next page that I show below:
The development of the applications is developed online and there are tools to establish connection with bluetooth and handling of images and links with others. There are 2 types of design windows: Blocks and Screen:
When you finish designing on the screen and programming in the block window the APK file is generated and then installed on the mobil phone, and from there you can control the stepper motors.
To run the application.
STEP 2: DEVELOPMENT PROGRAM
I designed a 5-button navigator to have 5 actions: Forward - Back - Right - Left - Stop.
I designed a 5-button navigator to have 5 actions: Forward - Back - Right - Left - Stop; But before I did a quick test of configuration in App Inventor as shown in the following figures.
STEP 3: TESTING THE APPLICATION
• With the " FTDI " wire upload program to Fabduino; as in the figure of the program developed, where five actions:
• Then I show a video where I showed the operation of the application with the hardware a test that I perform in my final project that has 2 step motors.
