quale shield per controllo motori?

-

salve tutti, dovrei acquistare una shield per controllare due motori dc di "piccola taglia". dovrei scegliere tra una di queste tre:
http://www.robotstore.it/product/358/adafruit-motor-stepper-servo-shield-per-arduino.html
http://www.robotstore.it/product/347/arduino-motor-shield-rev3.html
http://www.robotstore.it/product/258/shield-per-controllo-motori-2a.html

vorrei una shield versatile e diffusa nelle comunità arduino, che mi consigliate? la prima della adafruit mi intriga parecchio...

la prima di adafruit e' migliore perche' e' doppia rispetto alle altre, ok, ha meno corrente ma per piccoli motori va benissimo, pensa solo che con quella controlli 2 stepper o 4 motori dc, con le altre solo la meta' ;)

piace pure me quella scheda anche se con pochi componenti e una millefori la replichi facilmente (non cosi' bella pero :p)

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

-
hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
