Button Press timing/relay

hi guys, thanks far! wasn't sure post question since solution may either coding or hardware, thought place... is possible make single button press last desired amount of time? example, i'd single on/off button last 1 second within code. act relay in way activating relay cause turn on , off given time. for example, simple led on/off controlled using button: press button, led turns on, let go of button, led turns off. of course tell led stay on 1 second when button pressed once i'm trying achieve, think need 'led' 'think' button has been held down longer. so have like: if (button == high); =1000ms 1000ms = 'buttonheld' then in void loop, if (buttonheld == high) 'turnledon' does make sense? language wrong i'm not sure about many in advance, kyle sorry, meant post forum!

Arduino Nano GRBL ohne Shield a4899

hallo, ich habe hier zwei alte dvd laufwerke rumliegen, aus denen ich die schrittmotoren usw. ausgebaut habe. außerdem habe ich zwei a4899 schrittmotor-treiber von einem früheren projekt in meiner schublade gefunden. dachte ich, ich könnte ja mal anfangen und einen kleinen cnc laser bauen. habe ich den einen treiber mit einem arduino nano und einem motor verbunden und eingestellt. alles hat funktioniert. jetzt würde ich gerne anfangen und die cnc maschine bauen. diese würde ich gerne mit grbl steuern (vllt. kennt ja auch jemand eine gute alternative...), jedoch habe ich hier kein shield übrig. ich habe mir schon das pinout vom nano bei grbl angeschaut, jedoch weiß ich nicht, wie ich die a4899 dann mit dem arduino verbinden soll. es gibt ja 3 pins für step pulse (x, y, z), aber wo verbinde ich z.b. die vier kabel vom schrittmotor usw...? ich würde mich sehr über antworten freuen. sorry, wenn alles etwas umständlich und laienhaft erklärt ist. was genau brau

Issues Testing GPS

hello all, i have gps sensor-1 trying test larger project. want right see data in serial monitor make sure receiving properly. post code below, not think problem (granted new arduino language, , relatively new coding in general, modified code found on arduino website think it's right). basically issue this: if plug nmea stream rx pin on arduino (and ground) , plug gps power, data gps lock indicator light not come on. if reverse order , power gps before plugging in nmea stream, gps indicator light come on, turn off 30 seconds after plugging in nmea stream (yet receive data entire time). unplug nmea stream, , gps light on again. have of ever worked sensor-1 gps systems, or had similar issue? talked tech support, , while nice , trying best, best tell me "that's weird." here's code: code: [select] int bytegps=-1; int rxpin = 0; void setup() {  // put setup code here, run once: pinmode(rxpin, input); serial.begin(19200); } void loop() {  // put main code here

Problema con Driver DRV8825

Power Dissipation

Image
hello everybody, have small question regarding power dissipation. i wondering why multiple people suggest small transistor rated @ 500mw power dissipation 12v 350ma/1a circuits? here's few exemple : the transistor commonly refered following : http://www.onsemi.com/pub_link/collateral/2n2222a-d.pdf total device dissipation @ ta = 25°c pt 500 mw total device dissipation @ tc = 25°c pt 1.0 w http://forum.arduino.cc/index.php?topic=256336.0 350ma * 12, 4.2w http://electronics.stackexchange.com/questions/235830/npn-circuit-to-switch-12v-1a-dc-load-by-3-3v-1a-dc-using-pir this 1 use 2 transistor devide amperage assume, still not enough under 500 mw total power disspation. 12v *500ma, 6w. am not understanding how power dissipation works? did overlooked or assuming heatsink used? you're confusing power dissipated load power dissipated transistor . for instance, if supply 12v , load 12Ω, current through load 12v/12Ω = 1a. power dissipation in load 12v x 1

hey guys! i'm busy making project accelerometer @arduino can controle ellipse @processing but problem is, doesn't work. think has receiving 2 data's in processing @ same moment (value waardex & value waardey). hope can me out! my arduino code: code: [select] #include <wire.h> #include <adafruit_mma8451.h> #include <adafruit_sensor.h> int waardex; int waardey; adafruit_mma8451 mma = adafruit_mma8451();            //maak object acceleromter aan void setup(void) {   serial.begin(9600);                                 //begin seriële verbinding   serial.println("adafruit mma8451 test!");           //print waardes accelerometer   if (! mma.begin()) {                                //mma.begin() om de sensor te herkennen.     serial.println("couldnt start");                  //"mma8451 found!" bij goed signaal, "couldnt start" bij slecht signaal     while (1);   }   serial.println("mma8451 found!");

ESP8266 vs Wemos D1

what difference between esp8266 , wemos d1 wi-fi module. is there difference in programming part both of them. which more suitable arduino uno. wemos d1 esp8266 module power , usb support circuitry , uno style headers. it's substitute uno, not you'd use uno. think of uno wifi communication runs @ 3.3v instead of 5v , less beginner friendly. if want use esp8266 uno should either esp8266 module , necessary components supply > 500ma@3.3v(the 3.3v pin on standard uno not sufficient) or esp8266 shield plugs uno. quote from: nvt123 on aug 27, 2016, 10:47 am is there difference in programming part both of them. for programming them directly, no, esp8266 esp8266. however, if you're wanting use esp8266 uno you're going send commands uno esp8266 running @ firmware on serial using @ commands. require different code if uploading code directly esp8266.

Using a Raspi to get GPS data on video - Raspberry Pi Forums

having used couple of raspi's on wee boat (running opencpn gps , ais), wondered if possible use raspi gps data on network video recorder (nvr). use poe nvr 2 mast-mounted cams, 1 looking on bow, other on stern. nvr has 4 poe cam inputs, use 1 of these connect raspi third 'cam' record gps-position, -course, -speed , -time data. simple screen decoded data, nvr takes care of time , sync cam video etc. have no idea how ethernet port of raspi cope poe 48v dc, dedicated cat cable cut easlily made. so, gps connected raspi connected nvr 'cam'. leaves small matter how program raspi (!), gps sentences need decoded/extracted , presented ethernet port in ip video format (h.264 1280x1024). made this, ideas ? tia w fr greetings, leo done searching: need hdmi input , hardware hdmi > h.264 encoder. raspi has no input , has not enough speed , capacity encode hdmi signal. add-on hardware available @ price of €200+ without raspi opted 'black box' encoder €1
