data exchange between 2 Nanos with HM-10 : reducing packet length ?

hi, i communicate between 2 nanos using hm-10 ble modules, in independent bluetooth 4.0 network. my aim make measures using nano slave hm-10, lets every 200ms, , send packets of data , lets 1 3 bytes, independently @ rate, nano master hm-10. actually, can grouped data arrive master after moment :-/ as if hm-10 waiting calm moment before sending data ! so question : does know how fix length of packet, or force hm-10 send buffer ? thanks help, , apologies poor english, don't use :-/ quote thanks help, , apologies poor english, don't use :-/ your english understandable, mostly. code not. seems posted using 0 point font, in invisible ink.

PWM + switching power supplies

i have been moving higher-power electronics projects , looking if there potential issues using pwm-controlled power regulation through mosfets when power source electronic circuit such switch-mode power supply.  there potential issues drawing current such sources @ highly-varying rates such @ typical pwm frequencies (~1000hz) ?  don't want damage power supply i'm using 100w power now.  thanks. switch mode supplies have large amount of output capacitance act charge reservoir. keeps output voltage stable throughout whole switching cycle. if brief load pulses causing of transient drop, converter capable of average current output, can add more capacitance. power supply decoupling capacitors suspension system of car; work keep power smooth , level through bumps , jostles of erratically variable load.

Fehler im Programmcode bei 95% Auslastung

hallo zusammen, gestern hatte ich ein eigenartiges verhalten. mein code lief einwandfrei, alles hat genau gemacht, es sollte. auslastung programmcode 94%. dann habe ich eine zeile mehr programmiert und das ganze programm hat schlagartig totalen müll gemacht. strings haben plötzlich nicht mehr gepasst usw. dann habe ich die zeile wieder rausgenommen (alles tut wieder) und durch eine serial.println(); zeile ersetzt (wieder läuft nichts mehr). kann es sein, dass bei 94-95% auslastung (arduino uno) bereits ausfälle auftreten, ohne dass es eine compilerwarnung gibt? kennt ihr das verhalten? viele grüße quote 94-95% auslastung du hast eine auslastungsanzeige deinem uno? heul, meiner hat sowas nicht! stacküberlauf stack heap kollision array Überlauf pointer, welche in die wiese zeigen und nein, dieses kann der kompiler nicht bemerken.

Nuovo utilizzo del carattere "?"

osservando un listato presente negli esempi dell'ide ho scoperto questa nuova funzionalità davvero utile.     serial.println((val)?"high":"low");      val = 0    ->  "low"      val > 0    ->  "high" per come la vedo io risulta una bella semplificazione, senza ricorrere if e else. ho dato un occhiata alla guida di riferimento dell'ide ma senza trovare traccia del suo utilizzo. e' sempre una funzione ereditata dal c oppure non sono stato attento consultare le guide? esistono altre "scorciatoie" analoghe per rendere il software più snello? grazie del contributo e' del linguaggio c da molto tempo, direi da quando è nato. altro mi viene in mente solo      a=a+3;        semplificato in    a+=3; Arduino Forum > Int...

L293D, moteur DC et fréquence PWM

bonjour à tous, je suis bloqué dans mon projet de bras robotisé, malgré mes recherche je n'ai pas trouvé de solution. je me tourne vers vous dans l'espoire de débloquer ma situation. quatres moteurs dc sont piloté par une arduino, via deux l293d. lorsque je connecte directement mon alimentation aux branches des moteurs, ils tournent nickel. (alim 9v, moteur dc de récup je n'ai pas de datasheet) . les moteurs fonctionnent environ une fois sur cinq avec le programme. lorsqu'il ne fonctionnent pas ils émettent un léger son aïgu, et aucun mouvement. j'ai cru comprendre sur une video en anglais que cela pouvait venir de la fréquence du pwm de la arduino ?  si ce diagnostic est bon, avez-vous une solution pour savoir à quelle fréquence régler les sorties sans ruiner les moteurs ? dans le cas contraire, avez-vous une idée d'où cela peut venir et des pistes pour une éventuelle solution ? merci d'avance pour votre aide, bonjour, que...

slowing down a DCC loco in a "block" using an arduino or similar circuit ?

hi, i have been researching problem several days, no avail.  have read dcc packets etc, , how maybe capture them, want follows : i have 3 , 3 down line tracks hidden , intended hold trains in sort of sequence every time train approches  "fiddle yard" enters 1 of 3  vacant loops, starts slow down in 1st block section of loop track, , stops before reaches exit point/switch in 2nd block. 1st  block slow down trigger train waiting in 1 of other loops start , exit storage loops go around layout. in it's simplest form, want incoming train enter designated loop track, start slow down 1/2  speed in first isolated block (separate dcc feed), , when hits second isolated block (seperate dcc feed) stop, utilising programmed deceleration half speed or similar controlled 1st block, ensuring train come full stop before reaches exit switch/point. this allow me send random different trains around figure 8 circuit (controlled arduino) provide automatic vari...

[OFF TOPIC] - DIY de aparatos Zombies

Image
hola todos, soy matías, vivo en uruguay. recientemente adquiri una placa arduino/genuino uno r3, y estoy comenzando satisfacer mi manía de reparar o hacerle mods o fix aparatos electrónicos que han estado en mi casa como zombies sin morir del todo pero que tienen algunas fallas o no están del todo funcionales (pero algunos componentes podrían rescatarse). y nada mejor que una placa arduino para darle alguna nueva utilidad algo roto o que no esta funcionando como originalmente fue concebido que funcionara. bien luego de la presentación, me gustaría compartir con uds uno de los primeros proyectos que comenzado con mi arduino uno r3 una vez compre un mini parlante (radio, mp3, usb, sd, aux etc) el cual en pocos dias se estrello contra el suelo y desde ese momento no volvio funcionar de forma correcta. les adjunto una foto de la placa. este es el producto bien...todos los inputs que tiene (usb, microusb para la entrada de corriente de alimentación, sd y auxiliar de audio, funcion...

Bestimmung der Kurzschlusstromstärke in Abhängigkeit von der Abdunklung

Image
hallo, ich habe ein kleines problem. wir sollen mithilfe einer photovoltaikzelle, stromstärkesensor(kefa 301) und natürlich dem arduino die kurzschlussstromstärke in abhängigkeit von der abdunklung bestimmen. da ich ein totaler noob bin arduino programmierung angeht und ich nur befehle wie z.b serialprintln kenne habe ich keinen plan wie ich das angehen soll. ich hoffe ihr könnt mir helfen, auch wenn heute sonntag ist liebe grüße bydarcor quote from: bydarcor on jan 15, 2017, 11:38 am ich hoffe ihr könnt mir helfen, auch wenn heute sonntag ist klar helfen wir dir gern. nur wie sollen wir helfen, wenn wir keine deiner komponenten und deinen sketch kennen. also poste bitte die links deiner verwendeten teile, deine schaltung, wie du es aufbauen willst und den sketch, den du bisher geschrieben hast. damit du kein noob bleibst, solltest du allerdings die grundlagen des arduinos lernen. das kannst du anhand der beispiele in der ide. ...

Array

  salve amici di arduino  come posso in una array in cui ho assegnato questa variabile 6 spazzi come esempio sotto ,quando la richiamo per fare un serial.println ad esempio  serial.println(mia_str[0]) vorrei che stamperei schermo tutta la frase intera --testo-- e non solo la lettera t  ed ad esempio serial.println(mia_str[1]) unaltra frase--gatto-- nellesempio sotto capisco non e possibbile perche la variabile e di tipo char lettera , non esiste un modo per richiamare alla posizione mia_str[0] una stringa intera grazie code: [select] #include <arduino.h> void setup() {   char mia_str[6];   serial.begin(9600);   mia_str[0] = 't';   mia_str[1] = 'e';   mia_str[2] = 's';   mia_str[3] = 't';   mia_str[4] = 'o';   mia_str[5] = 0;   serial.println(mia_str); } void loop() { } cioè, data la posizione esempio 2 vuoi stampare da li al fondo ? devi passare ...
