The shield for arduino UNO was made with analog MUX / DEMUX 4067 IC and the shift register in the outputs 4067 IC, The Arduwire UNO include output for the Pass Green Led, Fail Red Led and Buzzer output and the I2C BUS. 

Features include:

  1. 32 (Test points).
  2. Green led pass.
  3. Red led fail.
  4. Buzzer.
  5. Library for Arduino.
  6. Easy to use.
  7. Expandable MAX 64 (Test Points).
  8. I2C BUS.

Easy to use with the IDE for arduino, please download the library.

How does it works?

Firstable it is necessary one cable for test, for example i will test one harness cable with 4 connections:

Then it is necessary attach the cable to the Arduwire UNO shield, after connect the arduino to the PC or laptop, and upload one example sketch with the IDE of arduino, please should be install the library arduwire UNO.

Wirelist learned:

This sketch it is found in the examples in the library for arduino IDE. Arduwire UNO library.
