ANALOG INPUT EXTENSION SHIELD FOR ARDUINO
WWW.VELLEMANPFORMAKERS.COM
Introduction
The Arduino UNO™ is equipped with 6 analog inputs but some projects call for more. For
example; sensor- or robot projects. The analog input extension shield only uses 4 I/O lines
(3 digital, 1 analog) but adds a whopping 24 inputs, so in total you have 29 analog inputs
at your disposal.
Features:
• 24 analog inputs
• only 4 I/O lines are used
• stackable design
• complete with library and examples
• works with Arduino UNO™ and compatible boards
Specications:
• analog inputs: 0 - 5 VDC
• uses pins: 5, 6, 7 and A0 on Arduino UNO™ board
• dimensions: 54 x 66 mm (2.1” x 2.6”)
