I want to create a "Light-Show" that can be controlled with the touches on an android tablet. But... LED is not enough, let there be light! So, let's switch on some 230V (I'm in Europe) light bulbs: That works fine with a small driver circuit like for example here: http://www.sonelec-musique.com/images/electronique_triac_001e.gif The digital outputs of IOIO can be connected to Cde input and the bulb goes on and off, so far, so good.
But I want to "Dimm" the light (similar to PWM). The keyword here is PFC or "phase cutting" (see http://en.wikipedia.org/wiki/Phase-fired_controllers). The IOIO output must pulse on and off at the correct position in the modulation cycle of the sinusoidal AC waveform. This means, that the IOIO munst synchronise itself with the modulation present at the input pin and trigger the output accordingly. Let's do not only LED cool stuff, but big cool stuff with 1000 Watts and more.... -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
