Great work! Is there any way to refresh faster(15 secs by default)?
Use Paid server. The refresh rate is 1 sec.
Nice,video
You have helped me complete my inlab IIOT task. Thank you.
Nice, Pls what about sending (powering) more than a bulb (device), Please help.
very easy to understand from this video, good work
thank you man, your videos are great
+nodari latsabidze .
thank you for comment
Thanks for the great work! Everything work until to I complied the code, Ardurino don't accept the "uint8_t = D6;" can you help?
Yes. Instead of D6 write 12 in code. Rest of the part is as it is.
Hi bro. I have got a little problem with code on Arduino IDE. This command ( WiFi.begin("ssid","passwd"); ) doesnt change my NodeMCU name. What should i do? Thanks for every help.
reset your nodemcu.
@@EmbeddedGate i did by RTS button but nothing happend
show me your code
sir this method can control 5 led lights brightness?
+Harichandran . Yes. This methods can control up to 9 LED brightness . PWM pins are D1, D2, D3, D4, D5, D6, D7, D8, RSV pin.
I watched ur video and ı do the same things with you.But i cant control my led.Im receiving the numbers and ı can see it on my serial monitor and also at my thingspeak,but ı cant control anything.I checked my control and ı tried to use a different pin but still same.
If your data not changing at thingspeak server then there is an error in your link. Copy your link add paste in Google browser and check data changing or not.
Its changing.
Did you make any changes in my code
Can you describe the hardware component..?
Use only a single led. Diagram is in the video description.
@@EmbeddedGate I was asking about the components other than led and breadboard.
Nodemcu, connecting wire, breadboard
@@EmbeddedGate Thank you 😇😇
please share how to control without server directly from phone hotspot. Thanks.
+Avinash Dwivedi. Didn't get your point. Please Explain .
@@EmbeddedGate Thank-you! For your reply :).. my point is to control led brightness directly from smartphone using wifi connection of esp and smartphone.. no internet connection between just wifi communication. 🙏
+Avinash Dwivedi . I will make video and post on TH-cam.
@@EmbeddedGate Thnak-your! :) if possibile use MIT app.
+Avinash Dwivedi. ok
Sir but this method is not supporting leb bulb(only supporting led small light) how can I support led bulb intensity 🙏🙏help.
If you want to control AC devices then you need to make a hardware circuit power transistors.
