Buttons installed

All buttons and LEDs installed, now time to hook up arduino and test a sketch

Changing resistors

The dome buttons are lit by a LED set up for 12V DC.  Replaced resistors in each LED with a 100 ohm resistor so now can use 5 VDC (30mA per pin) - would be better if it were 20mA but had 100 ohm resistors and arduino can source up to 40 mA per output pin.

Beautiful!

Test light and switch on Dome buttons

 First test the switch and LED on the dome buttons.  Ran simple Blink and Switch sketches on Arduino

Whack A Mole Dome

Inspired by Sparkfun and their Whack A Dome I started a smaller version with only 9 buttons. Using their code as a start, here goes

Cutting out board for buttons
Start of the prototype. Counter display is from Adafruit and will be controlled by Arduino Leonardo

CTD Mark 1

Finally Mark 1 version of the CTD is finished - after lots of careful planning to keep the PCBs on the datalogger shield, I needed to add a voltage divider so ended up with adding another board, so it looks like a dog's breakfast.

First data from CTD

After much coding and making, here are the first data from the CTD
