Students should check position the arm, and display it on display. For confirmation propriety of readings, student should move the arm using stepmotor.

This hands-on lab guide is intended for the Beginners.

Generally students need skill using I2C bus. For realising scenario, students need access to documentation for registers of sensors (accelerometer), I2C interface for display, and HD44780. Students should understanding rotating stepmotors rules (signal DIR and STEP).

1. using schematic, check ESP ports which I2C controlled,
2. using schematic, check ESP ports which DIR and STEP (stepmotor) controlled,
3. using sensor documentation check registers which acceleration,
4. using display documentation check way for display digits on HD44780,
5. check I2C address for every device,
6. write the program loop which:

• send command for reading acceleration for every axis,
• wait for processing
• transform result for display
• send this to display interface,
• send command rotate stepmotor,
• wait for processing,
• transform result for display,
• send this to display interface.
• move one step a stepmotors.

1. using the camera observe display and check credibility of displayed value.

NOTE: arm move only in 2 accelerometer axis. Reading of acceleration from third axis should be constant. (or with small fluctuations)

On display should be visible acceleration for every axis. (always below 1G).

Only way for validation is check display by camera.
