Description: The book presents 20 projects, the first start with the popular LCD 1602a display. The display will present the ability to display information received from the Arduino board. Previously, to view data from a sensor or variable, we had to send it all to the serial port monitor and the device lost autonomy. Now when using the display in arduino projects, you can send data directly to the display from any pin or variable, and a new world of project development on the Arduino platform will open before you.
