Trying to use PS2 mouse as a sensor, but it won't interface to Arduino

hi, i have been using ps2.h try data usb mouse supposedly supports ps/2 protocol, not working. when ps2.h goes through sequence resets mouse , sends instructions send data gets stuck @ point when mouse supposed take control of clock arduino can send instructions. i'm wondering if ps2.h written @ time before usb mice , isn't capable of switching usb mouse ps/2 mode. thoughts on appreciated. thanks, terry rozmus solved it. turns out genius mouse brought not backward compatible ps/2 though specification says is. must have exchanged sensor chip 1 ps/2 capability not present @ point. have usb mouse doing job wanted perfectly.

termometro con diodo

Image
sapete come posso fare un termometro con arduino sfruttando le caratteristiche di un diodo al silicio in conduzione inversa? non proprio da dove iniziare. qualche mese fa l'ho fatto scuola riportando sul voltmetro la temperatura. sinceramente ne prima ne ora avevo le idee chiare e vorrei approfondire il discorso con una esperienza. ho comperato un saccoccio pieno di componenti misti 2/3 kg nuovi poco prezzo ci sono tanti diodi ma come li distinguo? la tensione del diodo in polarizzazione diretta dipende dalla temperatura e varia di -1,7mv per grado centigrado. in pratica applichi una corrente costante e misuri la tensione sottraendo la tensione che ha 0 gradi. se non vuoi avere tensioni negative sottrai una tensione piú piccola.   http://www.fisica.unige.it/pls/linea1/2008-scuolaestiva_diodo-temperatura.pdf ciao uwe Arduino Forum > International > Italia...

Excel & Arduino uno

ciao tutti !! sono nuovo e volevo chiedere una cosa ! scuola stiamo realizzando il primo proggetto piacere ed io volevo far comunicare arduino uno con excel 2010! più precisamente su excel ho disegnato un display 7 segmenti e se clicco su un segmento allora arduino lo accende. quello che mi interessa e' come far dialogare arduino con visual basic !! più che altro mi interassano le istruzioni di visual basic per far dialogare due software.  se magari qualcuno ha trovato un esempio o magari lo sa già può cortesemente scrivermi anche solo come si accende un led con con questa procedura !! grazie mille chi mi risponderà ! ciao tutti !!!  xd per info... puoi anche collegare excel con arduino http://www.gioblu.com/tutorials/programmazione/189-arduino-e-i-grafici-in-tempo-reale-su-excel Arduino Forum > International > Italiano > ...

Regolatore 78L05 tensione out bassa

ciao tutti, stavo controllando un arduino standalone che ho fatto qualche tempo fa ed ho notato una cosa: il regolatore onboard 78l05 http://users.ece.utexas.edu/~valvano/datasheets/lm78l05.pdf non regola bene la tensione, dati 8.71 volt di ingresso da una batteria ricaricabile da 9 volt in uscita ottengo solamente 3.96 volt invece dei 5 volt che dovrebbe erogare... sul pin di uscita del regolatore c'è un condensatore da 10uf, niente condensatori in ingresso (il filo tra il circuito e la batteria è 20 cm in tutto ). ho fatto una prova anche senza atmega328p e la tensione misurata è 4.34 volt, leggermente superiore ma sempre molto insoddisfacente.. dal datasheet: min output voltage 4.75 volt il regolatore è una "sola"? il regolatore non è una ciofeca, però fornisce max 100 ma. forse il tuo circuito ne assorbe di più? hai provato sostituirlo con un altro regolatore? forse il c in uscita è troppo grosso, e potrebbe dargli noia anche l'ass...
