The pulses are"shaped" by passing them through an RC network before they reach their respective transistors. This "shaping" produces the fading effect between the colours.
The fade in/out time can be altered by changing the value of the capacitors. (C3, C4, C5). Reducing the value to 47uF will reduce the time to fade between colours. Conversely, increasing the capacitance to 200uF will take longer. The value of 100uf for the "fade" capacitor was found by testing to be the most suitable over a wide speed setting range. You may want to experiment with different values, especially at very high and low speed settings. Do not change the R6, R7 and R8 values as this will affect the led current and may damage it.
