A quick test / terminal Arduino I built.

Purpose:

• Box an arduino, so my kids don't keep kicking the wires
• 4+ inputs
• LCD display
• WiFi

I also built another one for Ethernet - see Arduino EthernetLCD

• TODO - photo
• TODO - Sketch for Analog input to LCD

Hardware Build

• Take one old Backup tape case
• One dremel
• About 20 minutes

This is rough, as I did not have much time - but it does the job. Nice thing is it is very easy to change, open etc. I can even leave it open with metre connected.

Hardware is:

• Freetronics Eleven (Arduino Uno compat)
• Async WiShield (no longer made unfortunately - looking at alternatives)
• I2C LCD (handy, just 2 wires)
• 5 buttons (resistor network analog input)

For this project I also need to add:

• Temperature sensor
• Piezo speaker

Analog Input to LCD

To get the values for the analog resistor network for my buttons, I wrote up this quick sketch.

#include <xxx.h>

Using ButtonEvent
