<br> This circuit is relatively simple. The red LEDs are attached to digital pins on the Arduino through the resistors. The white LED goes to Pin 13 (no ...
To keep this project simple, I soldered the resistors for the LEDs "in line" with the wire, shown in this photo. Heat-shrink tube adds both stability and insulation ...
&lt;br&gt; The voice module required a transistor to trigger the button. The video and photo attached show how to use the transistor in the parts list to trigger ...
This code loops the "brightness up" and "brightness down" on the LEDs, checking for motion at the top and bottom of the cycle. If motion is detected, it ...
I used a USB battery which should offer plenty of run time for such a simple circuit. An artificial pumpkin, hobby knife, and hot glue did the rest. ...
