Arduino 4: TKVoltmeter, Potentiometer LED Sweep, Circuit Controller

Here I use the example sketch called “arrays” and blended it with the “potentiometer” example from the basic Arduino library with some simple modifications to serve as a potentiometer LED sweeper, which can also…

Arduino: LED Twinkler: Basic Analog Input, Digital Output, PWM

The Arduino is a flexible platform for controlling all kinds of devices from all kinds of input signals. Here I demonstrate the most basic Analog Input — a voltage from a potentiometer — and…

Pulse Motors: SNOT Update 2: Arduino Data Display of Velocity and Energy

Here’s another SNOT update. This time I’ve cobbled together an Arduino data collection system. The Arduino monitors the gate signal from the SNOT controller circuit by the use of the pulseIn() function on pin…

Arduino 16: Magnetic Levitator Optically Controlled

Here’s the latest project, an optically-controlled magnetic levitator using the Arduino. The OSEPP Uno clone runs a sketch which senses the position and velocity of the levitated object, and sends a switching signal to…

Scoposcopy: Supplement: Arduino’s Method of Inductance Measurement

To complement the earlier video on inductance measurement by resonating tank, I’ll now show a slightly different method used by the Arduino inductance meter. The Arduino uses a bit of external circuitry to “strike”…

Tai Robinson’s Hydrogen Fuel Vehicle

www.americanantigravity.com – Tai Robinson describes a Toyota Tacoma he’s converted into a hydrogen fuel vehicle also capable of running from natural gas. Robinson describes how introducing consumer choice into the fuel market will help…
