Tech Demo 3 Progress Report: Whac-A-Mole

This video demonstrates the basic circuitry for Whac-A-Mole. The lever switch will later be replaced by a series of buttons held underneath the solenoids. When an extended solenoid…

Morse Code Light Bulb

For my tech demo I wanted to create a device where, when the sensor recognizes darkness, a speaker spits out Morse code for the word “on” and turns…

Lumi-Sonic Device

Demo Video [password: physcomp] I made an instrument with a SPST switch and a Photoresistor. I had a hard time debugging during this time, and I finally realized…

Tech Demo 2: Morse Code LED

For my second tech demo, I wanted to make a project using flashing LEDs to display morse code. After several failed attempts at using different codes and/or libraries…

Tech Demo 2: Audio Lightshow

This demo uses an array of LEDs and two sets of speakers. As there are 12 different steps in an octave, I used 4 LEDs to represent the…

Tech Demo 2: Metronome

Code: techdemo2 I used some of our technical lab code and adjusted the angle and speed to mimic a classic metronome.
