Light Sequencer Code

Light Sequencer Testing

Mess of wires First test - using arduino, one optical theremin circuit, and one LED. Potentiometers are used to control the rate of the flashing light, the tone, the pitch, and volume.

Arduino Light Sequencer Part III

Potential layout for control interface.
Time: each potentiometer controls a delay variable for the flashing LED. Brightness: each potentiometer controls the brightness level of the corresponding LED. LED: 4 LEDs used to display the brightness and timing of the corresponding internal LED. Switch: used to trigger 1 of 4 code loops or other definable code presets. Volume: each potentiometer controls the volume level for the corresponding optical theremin circuit. Tone: each potentiometer increases or decreases the pitch relative to the light input of the optical theremin circuit. Volume: one potentiometer to control the overall volume of the mixed audio output. On/off: switch to turn off power to optical theremin circuits, etc. Audio output: (4) 1/4" mono jack one for each of the optical theremin circuits. Output: (1) 1/4" mono jack for mixed audio output. Other input/output: USB for powering and altering Arduino code, reset button for Arduino, power jack?, and etc?.

Simple mixer circuit for mixing audio output from each optical theremin circuit.

Ujino Muneteru - Japanese sound/sculpture/performance artist

"Tokyo based Muneteru produces work informed by the urban experience, domesticity fused with club and dance music, the interpretation of musical histories, technological capabilities and the sophisticated transformation of domestic and popular ready-made objects into hybrid musical instruments.

Muneteru's practice is concerned with adaptations of language - musical, written and spoken, and the common connection established through a 'lost in translation' experience of dance culture. Controlling the performance from a platform of turntables, switch panels and instruments made from found recycled articles including a blender, hair-dryer, electric drill, food processor and bicycle, Muneteru's sounds trigger responses from the vehicle, which flashes in time with the variable beats.

As artist-in-residence at the Wooloomooloo Gunnery, Muneteru will spend several weeks scouring the op-shops and side streets of Sydney in search of the 'hard waste' that will be transformed into his musical instruments. Like a traffic inspired techno score, the presentation of Ujino and the Rotators is a captivating delivery of contemporary performance, and a reminder that performance art has mutated into the 21st century with sophistication and vigor." ~the-rotators.com

Arduino Light Sequencer Part II

Crude wiring setup: Test #1 using four LEDs and one optical theremin circuit. Timing and length of tone determined by Arduino code.
Sample of code: varying the numbers in the 'delay' command determines the length of each tone.

Arduino Light Sequencer Project

Use Arduino + code to control the rate and sequence at which four LEDs flash. Two switches are used to trigger two or more sets of sequences. Each LED will be coupled with the photocell of a simple optical theremin circuit. Each optical theremin circuit will transfer sound output to a channel on the mixer via 1/4" mono jack.

The intent is to create a simple sound sequencer that can be arranged using code + Arduino; which will form a foundation for further experimentation.
