Summary of Getting started with LCD's and Microprocessors
This article guides users on controlling a 16x2 LCD using an ATmega8 microcontroller with Bascom AVR software. It outlines the necessary hardware components and details the installation of BASCOM AVR and PonyProg programming tools. Finally, it instructs on building the circuit on a breadboard, emphasizing the use of resistors for the backlight if not integrated into the display.
Parts used in the LCD Control Project:
- Breadboard
- Wires
- ATmega8
- Programmer
- Bascom AVR
- 10k resistor
- 100k resistor
- 10k variable resistor
- 7805 Voltage regulator
- 100 µF 16V electrolytic capacitor
- 100n capacitor
- 16x2 LCD
