hola, hace tiempo que tengo en la cabeza: 1-crear un timbre para la casa con raspberry, con el que pueda configurar cualquier archivo mp3 para que suene al tocarlo. 2-también, ya que me pongo, que mande el mensaje al correo con foto de la persona que toca el timbre por si no estoy en casa. el caso es que de esta segunda parte sí existe bastante información en internet, pero en el primer punto necesito ayuda para poder realizar las conexiones y ver que material necesito. mi idea es sustituir el timbre normal de la casa, conectar el pulsador la raspberry y ,como cerca de la puerta tengo una caja de conexiones de electricidad, conectar la fuente de alimentación de la raspberry ahí directamente. lógicamente necesito un altavoz bluetooth, pero ¿qué más necesito? ¿cómo conecto los cables del pulsador la placa? encontrado un post de hace tiempo http://petazetabytes.blogspot.com.es/20 ... rbell.html da pistas pero que no me aclara todas las dudas la hora de crear el proyecto. os...

bonsoir à tous, ce sujet n'ayant pas grand chose à voir avec arduino mais en ayant quand même avec l'électronique et mon désir d'en savoir toujours plus, je poste donc dans le bar. j'ai recuperé une petite carte équipé d'un quadruple aop, qui permet la commutation de 2 relais, depuis la lecture d'un potentiomètre de commande et d'un d'asservissement d'un propulseur d'étrave à 360° un relais déclenche une rotation à gauche, l'autre à droite. il est impossible que les deux relais colle en même temps. via des transistor tip41c et tip42c mis en opposition, les relais sont commandé avec une tension positive ou négative sortant de 2 aop. ceci étant posé, j'ai reproduit depuis le ci, le schéma d'implantation à la main des composants après les aop, que voici (il manque 2 resistances sur les out des aop): ce qu'il se passe au niveau "logique": si l'aop 1 produit une tension négative, l'aop 2 en produira une posi...

buenos días, explico el proyecto en el que estoy trabajando, tengo 5 sistemas, de los cuales tengo que monitorear ciertas señales (analógicas y digitales) y enviar la información por ethernet una igu, la pregunta es que sería mejor utilizar para hacer la lectura de las señales (como dato son 30 o 40 señales aunque se tiene contemplado hasta 125), sería mejor multiplexar las señales y enviarlas un solo arduino por 5 entradas analógicas y las digitales igual pero pin digital o conectar 5 arduinos como esclavo y que lean las señales de cada sistema y luego poner uno como maestro que lea los datos de los 5 subordinados (todo esto por cable ethernet), los tiempos de actualización de datos son el critico de 1.5 segundos y el máximo de 4 segundos. si tienen alguna otra opinión será bien recibida, muchas gracias. algo como lo que estoy haciendo en este momento.  un raspberry pi como master y nodos usando nrf24l01 con un nano en cada nodo que quiera medir, pre...

hallo allerseits! vor ein paar monaten, etwa im herbst, bin ich hier im forum über eine sehr einfache schaltung gestolpert: ein solar-panel(chen), eine diode (1n4001), eine batterie (9 v block) und ein elko waren verschaltet, dass das solar-panel unter guten bedingungen einen teil der leistung der batterie übernehmen konnte, um einen arduino mit energie zu versorgen. damals habe ich die schaltung ausgedruckt und für den sommer (also ungefähr jetzt ...) geplant, das mal zu testen. nun würde ich das gerne mal tun, kann aber die schaltung nicht mehr finden. aus dem gedächtnis habe ich immerhin noch das hinbekommen: kann sich jemand eine solche schaltung erinnern und mir sagen, wo ich das original finde? gruß gregor hallo, treffer? gruß und spaß andreas Arduino Forum > International > Deutsch (Moderator: uwefed) > [gefunden] Sc...

i trying step down voltage ranging 5v-12v down 3.3v, using buck converter http://www.ebay.com/itm/mini-mp1584en-dc-dc-buck-adjustable-step-down-module-effect-higher-than-lm2596-/301668096806?hash=item463cd1db26:g:0waaaoswt6pvhnzf . however, seem seeing issue: input voltage: 5.5-12v output voltage: 3.3v -> ok input voltage: 4.5-5v output voltage: 3.9v input voltage: 4-4.4v output voltage: 3.1 why output voltage jump 3.9v 5v input? have handful of same buck converter, tested them , got same result. i have these http://www.ebay.com/itm/mini-dc-dc-converter-step-down-buck-power-supply-module-for-flight-control-car-/400985370863?hash=item5d5c9730ef:g:ufqaaoxy4t1shmyt , doesn't seem have issue. these converters appear output 3.3v when input voltage 3.8v-12v. does know cause , reason of voltage increase @ 5v? did have load on output? regulator can bit jumpy without.

i wanted create reset in code after event occurs, because untraceable reason, when event occurs (radio transmission) system hangs up.  have 2 spi gadgets on board, , although both work, radio hangs up.  timing or interrupt problem. so decided apply watchdog timer trigger after radio tx, allowing 15 ms. before resetting.  activated after point in code tx called.  not in main loop, assumed trigger once, each time called transmission.  boy wrong! so have timer resetting nano every 15 ms., , program upload kaput.  have bricked nano, or there way foil wdt , new code chip? thanks in advance assistance. press & hold reset during download, when ide shows "compiled xxx of 32xxx bytes" release it. file:preferences, enable verbose outputs, can make timing easier see when release button.

after have finished designing front cover has text in it, idea save 1 live text layer , 1 layer outlines? hide live text layer, leave outlines visible, , save file eps or pdf preserve vector. ii import indesign. practice convert text outlines of time? i'm concerned if indesign doesn't recognize fonts in eps file, rasterize text automatically no notice. forget eps save pdf , place that. indesign recognizes vector objects in pdf.

for sure, not connected analog input reads nonsense. picture 1 shows circuit , long , b connected there no floating signal. if not, analog input measures ~1,2 v instead of 0. nothing new. driving motor signal in case got broken connection critical. first thought: connect pulldown resistor analog input bad idea, because voltage divider. picture 2 shows same circuit diode , if , b not connected there no floating?! my quesiton: why work? mean diode shouldn't have changed anything?! quote connect pulldown resistor analog input bad idea, because voltage divider. not can see. use of pulldowns or pullups usual way solve problem of floating input.

hello guys, i need implementing lpf on mpu6500. know there 6 modes filter not know how implement in code. line add activate it can please me right line place in sketch make work? thanks, yossi the 2 left columns refer possible values can write part of register 29 - accel_config_2. within register, there fields name of accel_fcoice_b , a_dlpf_cfg (1 , 3 bits wide - respectively). this: 1. pick values want each of these fields 2. write values accelerometer using standard i2c protocol wire.h. the address data writing mpu 0x1d (in hex). corresponds register 29 since 29 = 0x1d. also, remember account 4 bits in accel_config_2 come before 2 fields accel_fcoice_b , a_dlpf_cfg. on how pick lpf values: you'll have ask more specific questions right answers. p.s. posting code wouldn't hurt either.
