Apparently, Pepsi is best consumed at a temperature of 45F. For my project, I created a simple circuit used to check whether the temperature of a cold drink…
The Ultra Sonar Bat detects objects within a certain range (I set it to about 60cm), and outputs a note within the range of C3 (131Hz) to A6…
For my SISO project I took a ring of LEDs and controlled them using a joystick. Moving the joystick around…
I used a photocell to activate the motor on a car whenever an object passed over it. Putting your finger or any other object over the photocell results in…
Using an ultra sonic ranger and two LEDs in series, I created an anxious device that is alarmed when something or someone gets too close. The values read…
