Excellent sketch but when I connect the power the relay energizes when it should remain off but instead it energizes without command. If I have to turn on a light bulb, an opposite action is necessary: the relay must be turned off. not energized when connecting the ESP-01 power supply.
It does work . But goes to sleep and doesnt repond after few minutes , Pressing the button doesnt do anything ., To correct , it has to be reset after every few minutes. Can you guide whats going on here ? THanks a lot
In the required materials should the Arduino IDE be listed? I have downloaded Arduino IDE for linux. ESP_01 does not show up as a Board. When the USB programmer is pluged in the Serial port shows up but ESP_01 is not one of the board types on that port. Is this video suitable for newbies to the IDE?
You must Install the Boards in Arduino IDE In Preference -> Additional Boards Manager URLs, add: arduino.esp8266.com/stable/package_esp8266com_index.json Or you can googling it Thank you
This video explain control a ESP device via its webserver page, so you can add more relays in 1 device, you can use ESP32 or ESP8266 with more GPIO. If you mean control more devices with 1 page, you can use node-red dashboard, it can connect more device an out control on a dashboard page
When suddenly the electric power supply goes out and at that time the status of the relay module is ON. Then the electric power supply turns ON again, does the status of the relay module remain ON?
@@amateamchannel3687, I think you cant. If you want, you must store the status in something, in additional relay, pararel with main relay and connect output relay as input. Esp will check the input as relay status in initial start up. And you must use another esp device like esp8266
Yes, thank you for the fast reply, at first I was trying to click on the links to download them and that did not work, but then I saw a download button in the upper right corner and that worked, thank you. 🙂@@YaserAliHusen
