11.9 Summary

This chapter has described the use of text based LCD displays in microcontroller based projects. All the projects given in the chapter have been tested and are working. Early projects are about displaying text and numbers on LCDs. Then, more advanced projects are given, such as creating custom fonts, LCD dice project, LCD voltmeter project, and measuring the ambient temperature and pressure and displaying on the LCD. The last project is the classical High/Low game, where the microcontroller guesses a number and the user attempts to find this number. The microcontroller hints when the entered number is higher or lower than the number guessed.
