LED PWM Lamp with Multiple Nodes

Overview

This LED PWM lamp controller illustrates how multiple lamps can be strung together in order to produce large sequence of light.

Explanation

Before the construction of the circuit, some points were specified wherein a pair of wires can be used to simply connect each LED lamp. An AC signal can be used as the power to the LED lamps where a low frequency would be wept from a low frequency to a high frequency. The LED would be turned ON by a band-pass filter built into each lamp when the frequency matched the center frequency of the band-pass filter. A LED chase sequence could be completed if the band-pass filters were setup right. Any one of the LEDs could be turned ON by jumping to different frequencies instead of sweeping. It would be easy to drive the desired frequency down the wires with the use of an H-Bridge driver chip.

Each lamp contains 2 MIPS of horsepower and as a string of lamps gets extended by adding more lamps, the amount of MIPS on the string also goes up. Humming along with 32 MIPS of processing power is a string of 16 lamps.
