Wiring relay with AC water pump

hey everybody...i'm doing self-watering plant http://www.instructables.com/id/self-watering-plant/?allsteps , came road block on wiring ac powered water pump relay. i wanted see if identify pins on relay (jzc-11f 005-1z 5vdc), closed , opened? , also, if explain how go wiring ac water pump breadboard? background info 1) this first time working ac power in project i understand safety precautions of working ac, if has important suggest, including obvious...please let me know. have done research i'm not quite sure how enough. don't want deter challenge because feel learn lot execution. 2) this first time working relay i understand pins relay coil pins, closed, opened, , common. i not understand wire should go pin. i not understand wires go relay coil pins , either of relay coil pins positive or negative, or work that i not understand common pin does. i understand "flyback" diode suggested , why important...is between 2 relay coil pins? i using 9v battery 1

Servo VS Attuatore lineare

Image
ciao ragazzi. schede ordinate (arduino mega2560 + adafruit servo driver) e ci stanno gia' impiegando troppo ad arrivare comunque ne ho approfittato per preparare un'intelaiatura del robottino e una zampa robotica. sto usando 3 servo motori (estrapolati dal mio vecchio cessna radiocomandato) per avere il controllo longitudinale, laterale e verticale (avambraccio) della zampetta (foto allegata). ora, mi sto perfettamente adattando all'idea dell'utilizzo dei servi ma poi, girando qua e la con google ho beccato questo: http://www.ebay.co.uk/itm/390595957552?sspagename=strk:mewnx:it&_trksid=p3984.m1497.l2649 un mini attuatore lineare! beh questo sarebbe davvero l'ideale per il mio progetto! ma... : 1) la logica d'allaccio e di utilizzo di questo attuatore e' la stessa dei servo? so che per quanto riguarda l'utilizzo dei motori spazzola, cambia tutto, rendendo obbligatorio l'utilizzo di shields o ponti h quindi ho il dubbio che anche l'ad

Need some technical informations and advices.

hello everyone; like said in last topic: http://forum.arduino.cc/index.php?topic=240124.0 i'm working on road traffic monitoring project. need technical informations , advices. first of all, start explaining how project work. want set arduino uno borads (equiped ir , ulrtasonic sensors) should send number of cars counted every minute (with zigbee) server (for data processing). the probem sending data every minute rapidly decrease bettery level, thougt use solar cells have lot of sun here in country. other thing i've thinked programe arduino board not send data when traffic stoped or number of cars counted not significant , put in sleep mode when road traffic reduiced (e.g. night). my qustions : how minimum energy arduino need work corectly (in case) ? what kind of battery should use , how power ? what dimessions of solar cells should use energy board need. ? (i live in hot country, sun not problem). if it's possible (approximative values good), give me energy cons

Nybörjare önskar hjälp med att styra ljus med MIDI-keyboard

spelar ett band där vi inte använder datorer eller sequencers utan spelar live på våra synthar (förutom trummaskinisten då). och jag vill ha något enkelt som jag kan koppla till voyagerns midi eller gate ut. gärna något med olika "program" så att jag kan klicka mig från att det t ex blinkar rött när jag slår ner en tangent till att de ljusare tonerna blinkar vitt och de mörkare blått. typ två-tre olika förinställda program. det behöver inte vara starka lampor utan kan nog räcka med en liten matta leds eller lysdiodrar. jag har grundläggande koll på analog elektronik och en hel del lödvana. har byggt några byggsatser (mfos weird space... paia vocoder och en 5w madamp rörförstärkare). men digital elektronik och programmering är jag helt nybörjare med. har haft arduino tankarna när jag planerat projekt med ljud och rörelse men som inte blivit av. Är högstadielärare också, så att kunna lite enkel programmering är väl inte fel det heller. lika bra kanske att ta det stege

How can I change the amplitude of a pwm signal ?
