i want turn on & off dc 1000ma current servo using pro mini pin (e.g. digitalwrite(transistorpin, high)). i'm wondering type of transistor recommended? i have 2 different transistors in hand: irf520 , bc547b (these came arduino starter kit), great if 1 of these work. sorry ask follow question before answered first question, gotta go bed soon.   so here is: what smart/simple way allow 2 different amp levels same servo without dropping current 0 during switchover? for example, @ 1 point, allow low amps (e.g. 50ma) servo, @ later time, want increase allowable amp level 1000ma. my first thought 2 separate transistors, 1 passing 50ma servo when activated transistorpin8, , 1 passing 1000ma when activated transistorpin9 (for example). the problem idea there short gap zero power going servo when digitalwrite(transistorpin8, low) , milliseconds later digitalwrite(transistorpin9, high). trying avoid "zero power going servo" situation. would ...

il mio goal e' quello di collegare un arduino nano due sensori via spi. entrambi dovrebbero lavorare 3.3 v, quindi ho pensato di utilizzare un logic shifter. l'unico dubbio che ho sono pull-up resistors. per ora ho messo 3 pull-up (10k) in sck, sdi, , cs e un pull-down (10k) nell'sdo. dopo varie combinazioni l'unica che sembra funzionare e' quando li metto sia nel level shifter 5v che in uno dei sue sensori e 3.3v esattamente con questa configurazione. tuttavia il  programma non va e mi da numeri decisamente sbagliati. qualcuno saprebbe dirmi quale potrebbe essere il problema e se ho messo resistors nel modo corretto? sulla spi non servono pullup o pulldown. ciao uwe Arduino Forum > International > Italiano > Hardware (Moderator: leo72) > Arduino NANO - Level shifter ...
