Magnetic Resonance Amplifier 6: Effect of External Magnetic Field

Please watch the earlier videos in this series first. Here I have the system tuned so that the applied magnetic field from the external magnets moves it closer to being in resonance at the…

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…
