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!

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...

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.
