Shield-A v2.0 is Arduino Uno based shield for student education compatible with BASCOM-AVR(C) and Arduino IDE.

Croatian version.

Introduction

Shield-A v2.0 is version of Arduino Uno based shield for student education compatible with BASCOM-AVR(C) and Arduino IDE. During programming please keep in mind next design rules:

• D0-D7 — LEDs can be used only if D12 is set to OUTPUT HIGH state
• LCD 1602 — can be used only if A3 is set to OUTPUT HIGH state
• RGB LED — are connected in matrix (D5-D7 - colors; D8-D11 - LEDs)
• D12 — enables D0-D7 LEDs
• D13 — reserved for buzzer
• A0 — reserved for potentiometer
• A1,A2 — reserved for switch in INPUT_PULLUP mode
• A3 — enables LCD 1602 back-light
• A4,A5 — reserved for I2C communication with on board pull-up resistors
