12. Output devices

This week I worked on defining my final project idea and started to getting used to the documentation process.

so in my output devices I need a display (LCD) I work this week to how to program LCD display and I design the IC2 board to minimize the connection in the microcontroller

I learn the datasheet of this display

LCD (Liquid Crystal Display) is a type of flat panel display which uses liquid crystals in its primary form of operation. LEDs have a large and varying set of use cases for consumers and businesses

This LCD need much traces to connect him so I think to design a board the IC2

The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families

the code arduino
