Hi Chris @chris101,
The hand pointing to my signature look was not intended, it was pure luck... ha!
(The eyes in the marbles near the counter are reflections from the two spotlights I used)
Maybe Ron Popeil will add a Marble Sort-O-Matic to his endless list of gadgets....
About the I2C connections on the Littlebits Arduino:
At first I soldered 6 male headers on the ICSP through hole connections and female headers on each throug hole connection on A2, A3, A4, D10, D11 and D13 for future use.
Those connections can then be used with wiring with male and female headers. No problem.
Also VCC and GND (they are in the ICSP rows) can be connected via these pins.
Then I soldered right angle male headers on the solder pads of D2 and D3, which are the I2C SDA and SCL connections.
These male pins are relative long and one day it happened.... I broke them off and not only the pins broke off, but also the solder pads were ripped from the surface....
So Bye Bye I2C......
I tried to fix it but without success. So now I own two Arduino bits, one with I2C and one without...
Then I made a much safer connection as follows:
Take two female headers and connect them via small wires to D2 and D3. Glue these headers horizontally on the surface of the Arduino.
Now you can connect wiring via a separate set of two right-angle male headers, connected to the wiring with female headers on one side and with the glued female headers on the Arduino.
when the I2C connection is not used you cannot damage your Arduino...
