Odd question it may seem.
I have 4 triacs controlling 4 240v AC bulbs.
The triacs are controlled by a PIC, with 0.5ms intervals. When i change the triac firing to the next step (0.5ms away) there is obviously a drop/or increase in brightness as you'd expect but its very notcy as you also would expect. Without changing from 0.5ms intervals, i want to smooth the output so the change is GRADUAL rather than NOTCHY
Im ok with 12V AC having capacitors after the rectifier, but not with 240v, i dont want to rectifier anything so where would i put a capictor, across the HOT and NEUTRAL? stupid answer i guess your gonna say
Please advise... also what type would you recommend and rough value, i want the delay to be roughly 1second long before it settles to its new brightness value.
By using capacitors i will get the soft dimming when im going DOWN in brightness, but going up i will still have the notches? meaning doing the work in software is the best bet (but its soooo long winded)
