buenos días, llevo tiempo con un proyecto de hacer un coche teledirigido. con piezas de coches destrozados, una batería lipo, un servomotor para la dirección y un arduino mega ya lo hecho hace tiempo. mi problema real es que quiero poder controlar el coche larga distancia y no consigo más de 20 metros. he probado con rf de 433 mhz, con módulo nrf con y sin antena amplificada. también con bluetooth y con un xbee normal(no el pro. todo estos equipos te dicen que pueden llegar 300m en zonas abiertas, pero mi experiencia me dice que fallan mucho antes. ¿alquien me puede orientar? está claro que busco algo con un precio razonable. gracias de antemano.

hello, i'm building 8x8x8 grayscale led cube. works fine far, have 1 problem: because cube needs lot of power, max 2-2.5a 64 bright white leds @ time (one of 8 multiplexed layers). since arduino can not provide enough amps, use external power source leds, lab power supply now. arduino powered usb, grounds connected of course. switch layers using mosfets, leds controlled using 4 tlc5940. later, make nice box 1 power plug. i know can use vin pin (and gnd) on arduino power it. read method needs @ least 7v, leds run on normal 5v. i'm relatively new electronics i'm not quite sure how solve correctly. thinking use 8 or 9v power supply (wall plug adapter) supplies enough amps project. power arduino via vin pin directly supply , use voltage regulator kit transform voltage 5v led circuit. would correct way this? i didn't quite know search i'm sorry if discussed here before. if so, post link helpful thread? afik if feed arduino though power ...

salve tutti, premetto che sono nuovo del forum e le mie competenze nel campo di arduino sono basse. ma cominciamo subito parlare del problema che sto riscontando :0 : ho ricevuto arduino solo due giorni fa ed ho cominciato subito scrivere qualche programma molto semplice...giusto per allenamento. come potrete vedere dall'immagine qui sotto ho collegato un bottone ad arduino e da arduino un led. la mia intenzione era quella di fa accendere il led alla pressione del pulsante. il problema sorge qui...il fatto è che quando parte il programma il led è già acceso e alla pressione del pulsante questo si spegne, quando rilascio il pulsante questo si accende. in pratica è come se facesse l'effetto contrario rispetto quello da me richiesto. ho provato anche ad utilizzare il programma di esempio incluso nel software di programmazione, che riguarda sempre il progetto bottone-arduino-led, ottenendo però gli stessi risultati. vi allegherò le immagini del programma e del circuito c...
