Instead of relying on ones and zeros like in a digital computer, analog computers perform mathematical operations on continuous voltages instead. This makes them well suited to perform calculations invol..." current

Three claps turn the light on and off and two claps toggle the color of the light between a cool, bright color and a warm, slightly dimmer color. The design of the circuit allows for customizability. Certain components c..." current

They use cassette tape players to create the delay effect. In the most simple form, they take the output from the guitar and record it onto the cassette tape, then further along the tape the audio signal that was recorded onto the tape is read off and..." current

The instrument uses a pair of high-frequency RC oscillators whose slight frequency difference creates an audible beat frequency through the process of heterodyning. The design aims fo..." current

Using this circuit, you can get a motor to drive something to the beat of music. The circuit takes an audio input and filters the signal with a low-pass filter to isolate the musical beats. The signal from the low-pass filte..." current

In traditional sequencers and also this sequencer, you turn a knob (potentiometer) to set the note for each step. So 4 knobs for a 4-step potentiometer. Modern sequencers are connected to a keyboard or a launchpad. A sequencer can record in step time o..." current

Once the reaction button is pressed after the red reaction light is turned on, the Arduino and a shift register send the time it takes to press the button to a 4-digit 7-segment display. A false start mechanism using logic gate..." current

This is a modulation pedal and creates a "whooshing" effect by shifting different frequencies in and out of phase. This is achieved through 4 building blocks: the power supply, input buffer, phase shifting stages, Low Frequen..." current
