USB adafruit trinklet mini > AC voltage regulator ~5W/230v motor?
hi folks.. i have this little project running..
what i have: adafruit trinklet mini with 5v ATMEL microcontroller
what i want/need: REGUALTE a small 5w MOTOR using 230v ! (i already have a mechanical potentiometer at 30k ohm attached directly AC.. BUT..)
i know so far with the atmel i can f.ex. control a digital potentimeter 50k ohm, at 5v.. -> only DC no AC (+ i wont get a 1Ampere on 5V working) ------> my little MOTOR uses ~ 22mA on 230V = 5W
and what ive learned so far is that i might need one or two TRIAC or DAC combined with a POTENTIOMETER.. to control AC voltage
and/ or an OPTO-ISOLATOR --never heared of that before..
but i have no idea how i should solder that together or will i need some extra RESITORS or CAPACITORS for it?
-> FINALLY i want to flash the ATMEL with a small arduino code and use a USB connection (+own software) pushing the potenial (resistance in the curciut) from 0 to 50k ohm into AC !
