What do you do while building?

what do when building arduino (designing, soldering, building, experimenting) do listen tv in background? do listen music? kind of music? songs enjoyable work to? do listen nothing silence? do talk someone? interested hear people while working arduino. i designing next project in head, when gets exciting leads me putting leds in backwards :-) Arduino Forum > Community > Bar Sport > What do you do while building? arduino

driving 12 transistors with few I/O's - is it possible?

hi, i've build waveshield (http://www.ladyada.net/make/waveshield/) and have 12 push buttons (with 12v lamps inside) split out on a0, a1 , a2, each own resistor ladder. in addition this, able switch specific lamp on when button pushed. initial thought use 12 transistors , turn them on/off digitalwrite. apparently wasn't going straightforward thought, because have 10 available pins (a3, a4, a5, 0, 1, 6, 7, 8, 9, 12). so either can try making longer resistor ladder , see if can have buttons on 1 analogin-pin, or else know if there kind of smart way drive 12 transistors with, say, 2 or 4 i/o's? kind of matrix or.. don't know. well if have @ least 4 pins available, can use 4 - 16 demux here .

Problema libreria arduino keypad in processing

ciao ragazzi ho acquistato un tastierino 4x4 e lo fatto funzionare in arduino. dato che devo scrivere su un "blocco note"  devo utilizzare processing. qui nasce il problema, non sò proprio come fare passare la libreria keypad di arduino in processing. questo è il mio codice in arduino: code: [select] //definisce pin per comandare le luci const int rele_1 =  13;      // luce 1 const int rele_2 =  4;      // luce 2 // definizione tastiera #include <keypad.h> const byte rows = 4; // quattro righe const byte cols = 4; // quattro colonne // definizione mappa della tastiera char keys[rows][cols] = {   {'1','2','3','a'},   {'4','5','6','b'},   {'7','8','9','c'},   {'*','0','#','d'} }; byte rowpins[rows] = {   8, 7, 6, 5 }; // connessione dell...

External power supply not working?

hi,   i'm using arduino uno motor driver shield. when arduino connected pc via usb cable fine: motor turns wheels. when connect 9v battery, nothing happens, except status led blinks few times. i've seen in troubleshooting section: quote why doesn't sketch start when i'm powering board external power supply? (arduino diecimila or earlier) because rx pin unconnected, bootloader on board may seeing garbage data coming in, meaning never times out , starts sketch. try tying rx pin ground 10k resistor (or connecting rx directly tx pin). but didn't me @ all. please help!! small 9 volt batteries have little current capacity power motors/servos , other components have higher current requirements, need external dc power source has higher current capacity. lefty Arduino Forum > Using Arduino > Installation & Troubleshooting ...

RF 433mhz. Missing antenna? (lots of junk receiving)

hi all, i got (as many others) set of rf 433 tx/rx ebay. like: http://www.ebay.com/itm/1pcs-433mhz-rf-transmitter-and-receiver-kit-for-arduino-project-/261041100836 xy-mk-5v , fs1000a (xy-fst) while connecting it, i'm picking lots of noise/junk on receiving end (continuously). my questions following: 1. on both units there no external antenna's , mean there missing? 2. see on both small hole 'ant", assuming need attach own antenna?  tx/rx need both one? 3. assuming small tiny copper wire (spiral), antennas, maybe i'm wrong? many thanks! 36r looks intended have antenna.  think straight piece of bare wire  17.3cm long appropriate.
