Here we have the lead to our power button and the audio pot for volume control.
For out laser array I used a separate power source in the end to extend the runtime of the unit dramatically. I simply used some glue to hold it firmly inplace.
So now onto the modification to the speaker. Basically we are removing all the components we can down to what you see here. This frame contains the speaker amp and power switch. We cut the leads for the power source at the battery pack, and soldered the switch wires together to it is on all the time (when the arduino is on) then applied hot glue to the board bottom to secure the wires in place.
Here we have the beginning of our instrument. We mounted our arduino, speaker and battery pack and connected them. The positive lead to our arduino from the battery pack has our power switch inline, and our speaker is connected to the general ground of the arduino and pin 5 for our beep output.
Next we added our breakout board to connect our CdS to our arduino. Has I been thinking I would have bridged the CdS to the common lead inside of the block and not with the giant terminal on our bread board. Oh well… future refinements.
