I measured the temperature over the span of a day (around 12 hours) using the internal memory of the arduino and a 9 volt battery. I added an LED…
These three lights in this circuit turn on one by one, as long as the ultrasonic sensor detects a sharp change of distance within 1 second. So, if…
For my Temporal Machine, I created an introverted LED friend who pulses slowly in a blue-white glow unless someone comes too close! The LED “breathes” by pulsing gently, but starts…
I created a three note piano. Each button corresponds to a different note and the note is played as long as the button is being pressed. I attempted…

The needy bowl will freak out if you leave it. It will calm down when you come back but will take longer the longer you are away. Why…
A lonely clock that speeds up its ticking when it detects an approaching object. Might it be a friend?! The clock can’t tell, it doesn’t get out much….
I used a photoresistor to vary the voltage that was the input for my speaker, thus allowing changes in light level to vary the volume the speaker functioned at.
Using the Arduino, I created a device with an input-output relationship where as one gets closer to the Ultra Sonic Ranger, the distance is read and the LED…
