@@AhmadLogs , Good morning boss, u are very great for the great tutorial... Help ! I used this same method for nodemcu, but the blynk app takes 5 seconds to turn the relay or off ... What can I do plz...?
Yes boss, it's working perfectly with the push button... But sometimes it will work perfectly online with the blynk app, while after some minutes... It starts delaying for 6 seconds before turning on , also takes 6 or 8 seconds to turn off too.. But Ahmad Logs(Boss) said I should try put pull-up resistor, which I never try... But I will...& get back to the platform ..
Sir I make the same project using esp32 and 4 channel relay. The project works fine after uploading but after power interruption or when reset button is press it doesn't work and there is a single led glowing in dim light on the relay. Please help me how to solve this problem.
Very nice video. If you have the time, I’d like to see a video showing how to enter WiFi credentials via the mobile app, instead of embedding them in the ESP32 firmware. If I understand it correctly, the new Blynk 2.0 allows you to do this. Thank you!
@@AhmadLogs yes! OTA is another nice feature. If you can figure out the issues, and make a step by step video, I think it would be very popular. I have not found a good video about these features yet.
@@tzampini you are right. I have also tried different tutorials on blynk 2.0 OTA but unfortunately no success. I have also reached blynk forum for this. but did not find the solution. that's why my videos does not have this great feature. I afraid if I will get the solution in the future.
I have this project with complete documentation. Features are 1. Door lock and unlock through fingerprint. 2. Water pump control system 3. Pir motion with lighting 4. Gas detection and exhaust system. 5. All status are shown on blynk iot app
How do I connect the power to the the esp32 if I use the 5 volt pin as VCC? Currently, I am using the Vin pin as 5 volt power to the esp32. If I use the 3.3V pin as power input, then I think I will not get the 5 volts to be present on the Vin pin? Where do I supply power to the esp32 once I disconnect the USB from the computer? Thanks!

Your project might not be working properly because the power supply you are using is not providing enough power to the relays. You can try connecting the 5V power source directly to the relays to fix the problem.
