Working with both Arduino’s

Okay, to work now. I’ve connected the pre-built VMA100 to my MacBook Pro to be able to program it. The separate ATmega328 chip from the barebone kit has been programmed as well.¬†Power for both chips comes from the USB connection.

 

The VMA100 UNO

Has been programmed to make it’s LED blink, dependent on the amount of light that is being measured by an LDR. Less light => faster blink.

The VMA100 (Arduino UNO compatible, strapped to the breadboard

 

The barebone ATmega328 chip

Has been programmed to vary the brightness of a connected LED inverse to the amount of measured light by another LDR.

The ATmega328 chip from the barebone kit built up on the breadboard with it’s own 16MHz clock crystal

The LDR’s

Connected to the breadboard.
