New to programming and wanted to thank you for the video. Takes me 1 step closer to my "goal" project. I wonder, do you take requests? I would love to learn how to take this 1-2 steps further and make the on/off a time based function, and how to alter those time in a menu. My final idea is larger than this, but as of now, I've not seen 1 tutorial online on how to do this....

I have so many videos on wifi based controlling device also in esp8266. Just search for Robojax esp32 and I am sure Will ffind and learn from them for your projects

I have NODE MCU esp 32 wroom devkitv1 . It has no 5v output. (Only one 3.3v output) if I connect relay module eith external 5v power source and connect only the data pin with ESP 32 board, will my relay work? Will the ESP32 burn? I understand that the above question can be answered if I knew 1. Relay connected with just an external power source (no pins even data is connected with esp 32 board). What is the voltage reading of data pin of relay? [ I believe it should be 0, since this is just a triggerer] 2. Now I have connected relay module's data pin with ESP32's any data pin and relay's power is again given from external source. Will the ESP32 be able to trigger relay now? Please answer I am having hard times.

Yes you can connect data and GND and it will work.

Hello, I 'm not sure to properly understand, at 1:40 you mean than one is a 5V electromagnetic relay, while the other is optocoupler which may either switch on 5V or 3.3? Additionnaly, you mean than eventhough if one binds to VIN(5V), the switch is powered at 5V, but its logic still needs 5V but the board only delivers 3.3V and so the HIGH status is unreliable? Interesting, but then what's the use of having a 5V VIN??

Hello, all your questions are answered in the introduction to ESP32 which seems you have not watched. here kzread.info/dash/bejne/X2F6zJqKdM-tpbQ.html

You have an amazon link to the esp32 you used, but I can't seem to find the 3.3v relay module anywhere.

Use 5v relay. ESP32 has 5v power pin.

@@robojax Ah! Thanks, I have a 5v coming. I have a device that turns on a 12v fan that I'm hoping to use an an input signal to an esp32 to then trigger it to send out a low power bluetooth beacon of 'on' for a second esp32 to sense and have it trigger on a relay. If the ESP32 can drive a 5v relay that gives me more options. So many of the relays I have found on Aliexpress and Amazon use a shared power source for the trigger voltage AND the relay coil voltage. I don't want to pull enough current from the trigger to drive the relay, just to signal a data 'high' to tell the relay to turn on. Seems like that must not be a common use case from the sheer volume of 'maker' relays I've seen online that use the shared input design. Thanks!

You are welcome.Yes if you get relay module that has driver on PCB they need very little current. So you should be okay. Stay safe and don’t forget to subscribe.

Hello Ahmad , i wanna ask you a question , can i control a relay from anywhere using EPS8266 or it should be only over the same wifi? for example can i control the relay from my phone application over internet regardless the distance between the eps and the command? Waiting for your reply dear, Thank you

Hi, no you can’t . This just in your own network. If you want it from outside home, they searching for “how connect to my home computer over internet “ and if you solve that, then you can do the same with this internet of things IoT.

You need to provide external power supply for the relay By changing the jumper

Hi, you know if you post your comment under any video, I will see it. I have a separate page where all comments are shown in one page. So make sure to post your comment under Solid State relay video. Now to get solid state relay you visit eBay.com or Amazon.com or any other store and just type "solid state relay" and you will find it.

this is the first time I am hearing about "amazon pay". Wow something new. Udemy is using their preferred payment methods and I have no control over it. Sorry.
