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…
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…
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…
Photoresistor scale Video VIDEO LINK For this demo I set up a string of photoresistors to act as switches for a ‘keyboard’ of lights corresponding to notes in a…
In this demo the tone of the sound being output by the speaker changes depending on the user’s hand orientation using a tilt sensor.
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…
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…
Code: techdemo2 I used some of our technical lab code and adjusted the angle and speed to mimic a classic metronome.
