the last days tried tft-display via spi working on arduino pro mini. after several times of trying , failing, decided test arduino nano. on nano worked. program tried "graphicstest"-example adafruit-st7735-library, changed absolutely nothing. after measuring oscilloscope, found out, pro mini slower nano. both running on 5v , 16 mhz same program, "graphicstest". the voltage powers both coming same device. the blue signal signal nano, yellow 1 pro mini. after switching on voltage, can see on diagram signals generated nano starting earlier. also, not lasting long signals pro mini. if zoom in, can see "single" pulses longer on pro mini. example: first single pulse nano lasts 8us, first single pulse pro mini lasts 13us. both china. both have atmega 328p on board. the pin used in picture measurements pin 10 on both devices. chip-select-pin on tft-display. display wired correctly. why behave this? , how can change this, because need pro mini. the url di...

i have hc-06 on arduino simple code turn on , of led. when try pair computer (windows 10) , asks pin (1234 default far know). when press connectit says "that pin didn't work , try connecting again) on android says "unable pair , make sure ready pair" quote from: chrifdexter on jul 24, 2017, 06:00 pm i have hc-06 on arduino simple code turn on , of led. when try pair computer (windows 10) , asks pin (1234 default far know). when press connectit says "that pin didn't work , try connecting again) on android says "unable pair , make sure ready pair" were powering hc-06 when trying pair? did double check pin 1234 via @ commands?

bonjour tout le monde, je suis novice avec arduino et je bute sur un truc. je souhaite faire un compteur avec 4 digits. le câblage est bon mais lors de l'exécution du code les 4 digits restent allumés. je vois que cela incrémente bien mais les chiffres se voient à peine. je m'explique : les chiffres s'allume complètement, on voit un 8 avec point décimal. lors du comptage le chiffre change mais je vois toujours le 8 affiché. un faible scintillement apparaît. j'ai essayé de changer la valeur de  " setbrightness " mais cela change rien . quelqu'un pourrait me donner une idée code: [select] #include "sevseg.h" sevseg sevseg; int pina  = 9; int pinb  = 8; int pinc  = 7; int pind  = 6; int pine  = 5; int pinf  = 4; int ping  = 3; int pindp = 2; int dig1 = 13; int dig2 = 12; int dig3 = 11; int dig4 = 10; void setup() {   byte numdigits = 4; // nombre de digits    byte digitpins[] = {13,12,...

mmm ho scoperto da poco questa funzione. sto sviluppando un componente che si comporta diversamente seconda del tipo di utente 8uno fa domande e un altro risponde) usavo un controllo del genere: code: select all if($my->usertype == 'registered'){ // codice per user registered } else if($my->usertype == 'publisher'){ // codice per publisher } else{ showerror('non puoi accedere questa sezione'); } posso lasciare tutto così o è meglio cambiare tutto con acl_check? nel secondo caso sapete spiegarmi bene com funziona acl_check che ho guardato nel dev_book ma non ci ho capito moltissimo? poi test acl è sufficiente farli nei file "componente.php" senza ripeterli nel front_html? tanto metodi della classe dentro componente.html.it vengono tutti chiamati dal file .php. o è meglio ripeterli?

regars, i´m develping project tha involves more 16 analog sensors, i´m considering use arduino mega, wondering if there other model can allow more 16 analog inputs. i´m cosidering use multiplexer im trying reduce costs regards eliel rodriguez elielorgz03@gmail.com you can use analog multiplexer/demultiplexer (as arduino uses internally too) connect 8 different analog sensors each analog input of arduino. using uno 48 analog input channels. one example find in playground .

i have arduino uno set digitally control when magnetic lock enabled or disabled through digital pins. i have digital pin going through 1m resistor, lets me have maglock off while digital pin set output, low. if turns input, high, maglock enable. if change input, high output, low, still holds charge , won't disable. what can fix that? thanks. please post schematic of connections , data sheet maglock.  Arduino Forum > Using Arduino > Project Guidance > Arduino can turn on a mag lock but not disable it? arduino

hello, i'm trying update jre1.6.0_18. followed instructions in following thread: http://ubuntuforums.org/showthread.php?t=539423 , made sure replace jre1.6.0_18. supposedly configured sym links... ran jave -version , comes following: java version "1.6.0_18" java(tm) se runtime environment (build 1.6.0_18-b07) java hotspot(tm) 64-bit server vm (build 16.0-b13, mixed mode) when go java.com site , check java version, following message: oops! don't have recommended java installed. your java version version 6 update 15 when checking sym link (java-6-sun), looks hasn't changed. still pointing older version. can me out , tell me need change sym link point update 18??? directory java-6-sun , jre1.6.0_18 located in: /usr/lib/jvm solved: did little more digging , found in forum: http://sites.google.com/site/easylinuxtipsproject/java regards ...
