This is the 8 step sequencer that I’ve been working on. It’s been a little slow going, testing a variety of LEDs, photo-resistors and other components, but last night it started to come together. I’ve had issues with getting both the control and indicator LED to pulse together and without issue…. something that was solved through using a series of diodes in the circuitry between the IC and the final two LEDs.
Tonight will consist of wiring the rest of the indicator LEDs and wiring both the control LED and the audio line.
In the end this project will gate audio on and off in an 8 step sequence. This is accomplished by connecting a control LED to a photo resistor that splits the audio line input. When a light turns on the audio is passed through, when the light is off, the audio stops. With an 8 step pulse chain there is the possibility of beginning to build more and more complex rhythmic patterns. I’ve got a reset button on the surface so that the pattern can automatically be reset to step 1 of the sequence, though we will see if that helps with beat matching. In any case, more photos tonight or tomorrow and hopefully a little bit of video as well.
