Does someone now how i can flash my ligt on 1hz. I want to do it in a function.
this is what i have for color, now i want to flash it on 1hz??
Did you search the forum/flows ? Did you read the documentation ?
To flash the LED, you will have to send it a message every second to turn it on or off.
How long do you want to flash it for? I assume at some point you'll want it to stop flashing? How do you control that?
So i use a numeric: 1 is led1 blue / 2 is led1 red / 3 is led1 green /.... 8 colors long.
than 9 needs to be led1 blue but flashing at 1hz the holle time it may only go out if i change the numeric.
I searched some thongs about blinking a led and found some information .
i have a flow when payload 9 is set by numeric led 1 flash every 2 sec. But i want it to go out when i change from payload .
this is info that i found : [{"id":"740a99d2.b07d1","type":"function","z":"b71ac87f.d81188","name":"startBlink","func":"var BLINKDELAY = 250;\n\nvar light = true;\n\n\nvar blinker = setInterval(blink, BLINKDELAY);\n\nglobal.set("blinker", blinker);\n\nfunction blink () {\n \n if (light) {\n msg.payload = 1;\n light = false;\n }\n \n else {\n msg.payload = 0;\n light = true;\n }\n \n node.send(msg);\n}\n\n\nreturn;","outputs":1,"noerr":0,"x":282,"y":153,"wires":[["41b167bc.bbffc"]]},{"id":"73f5f278.0231bc","type":"inject","z":"b71ac87f.d81188","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"x":126,"y":153,"wires":[["740a99d2.b07d1"]]},{"id":"41b167bc.bbffc","type":"rpi-gpio out","z":"b71ac87f.d81188","name":"","pin":"15","set":"","level":"0","out":"out","x":471,"y":153,"wires":},{"id":"cc1b11b1.bebb28","type":"function","z":"b71ac87f.d81188","name":"stopBlink","func":"clearInterval(global.get("blinker"));\n\nmsg.payload = 0;\n\nreturn msg;","outputs":1,"noerr":0,"x":288,"y":225,"wires":[["41b167bc.bbffc"]]},{"id":"5db82a6c.1b547c","type":"inject","z":"b71ac87f.d81188","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"x":123,"y":226,"wires":[["cc1b11b1.bebb28"]]}]

Your flows are not importable. Please read this thread and edit your previous post to fix the flows.
My version of blinking LEDs... Might be overkill for what you want...
