Hello all! Here the situation: I have all mi pieces wired up fine and working, my project drives an RGBW LED, high power (e.g. Luxeon or similar) using a NPN transistor wired in the classical way. This LED ha to work on the same circuit of a "wave shield" I have optimized and miniaturized that with…
