Specifications

 

The Shield uses the following contacts Arduino:

A0 - button Set
A1 - button Menu
A2 - button Down
A3 - button Up

8, 9, 10, 11, 12, 13 - display

3, 5 - tx, rx pH Circuit

6, 7 - pumps pHDown, pHUp

Power supply for the pumps is taken from Vin Arduino

 

To assemble the device will need the following items:
1. Cyberplant pH Correcnor Shield
2. Arduino Uno or Arduino Mega
3. pH Circuit
4. pH sensor
5. power supply unit
6. Couple peristaltic pump
7. display

 

Installing the Library

In the sketch used library EEPROMex
for nonvolatile memory

Learn how to install the library on the site of Arduino: http://arduino.cc/en/Guide/Libraries.

ways of expanding

Board is designed in such a way that allows you to connect
Shield for the remote control, the same as the Ethernet Shield,
WiFi Shield, Bluetooth Shield.

It is also possible to use instead of pH Circuit other sensors boards from Atlas Scientific, such the Conductivity Circuit etc.

Also on the Arduino board after installing pH Corrector Shield remain free contacts, which can also be used to connect a variety of sensors and control devices.
