Very easy scenario. Students should read temperature and humidity in the lab, amd display it on display.

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 (temperature+humidity), I2C interface for display, and HD44780.

1. using schematic, check ESP ports with I2C controlled,
2. using sensor documentation check registers with temperature and humidity,
3. using display documentation check way for display digits on HD44780,
4. check I2C address for every device,
5. write the program loop which:
6. * send command for reading temperature,
7. * wait for processing
8. * transform result for display
9. * send this to display interface
10. * send command for reading humidity,
11. * wait for processing,
12. * transform result for display,
13. * send this to display interface.

Describe scenario to let the user understand its idea and process. Write information about the approach, algorithm, etc. (depends on the lab). Provide useful information about protocols, assumptions, addresses (i.e. communication servers), credentials, etc.

Describe expected result when scenario is finished.

Write starting conditions, i.e. what to do at the beginning, what to pay attention before beginning, how the mechanical part should look like, etc.

Write some extra information if i.e. some steps are optional otherwise cancel this paragraph (but do not remove header).

Describe activities done in Step 1.

…

Describe activities done in Step n.

Provide some result validation methods, for self assesment.
