I spend 8 hours to identify the problem. Eventually I soldered everything to the Arduino protoboard. Now it works :)
Nice👍
The legend is back🔥🔥
Thank You !
i have a 8266 12e module can i use a ch340 board tx rx conections & remaing setup to program it, wanted to install wled into it.
Yes, You can use ch340g board. Don't forget to put the jumper to 3.3v.
👍🇮🇳
I have Esp12e and Uno. Do I need anything else other than a 10k resistor while doing this?
It would be good if you have 2 tactile switches.
And then how to release the gpio 15 pin
Nice demo. What is CHPD connected to 3.3v ?. is it labled "En" ? ESP-12F board
Yes,It's enable pin(En).
@@ElectroRetro Thanks a lot.
Can the multimeter be replaced with a battery or power bank as an external 3.3v power supply?
Yes
"A fatal esptool.py error occurred: Invalid head of packet (0x4F)"?!
sir, why does my esp8266 wifi module always restart itself when the relay is in the close position and connected to AC current, but when the AC current from the relay is not connected and the relay is in the close position, the esp8266 wifi module is fine, I have used a relay that has an optocoupler?
Do you have flyback diode connected to the relay? If yes, then it may be electromagnetic interference from relay.
can a flyback diode fix this?
@@alifghifarii8428 it may fix.
Did you have to use another adapter before connecting the module to the arduino?
Did you mean that breakout board? I made my own breakout board for esp8266 to plug-in ESP in the breadboard. You can buy a ready made breakout board for esp8266.
@@ElectroRetro I'm sorry, i don't understand very well yet how to use this module. I've seen in another videos that they always use some type of adapter to program the esp, like the usb to serial or the nodemcu... and I thought that if you were using the arduino IDE to program the esp and the arduino uno board as an adapter, then you should disconect the atmega microcontroller from the board to do it... but after watching your video i realiced that it's not necesary..
@@ElectroRetro And do you have to do something so the esp can understand arduino IDE sketchs? like when you install the boatloader in the atmega328
Here am using an Arduino board as a USB to serial converter. You don't need to remove atmega328 ic if you short reset pin to GND. You have to add esp8266 boards in Arduino ide before uploading the code.
@@ElectroRetro i hope it works with my esp12e i had a nodemcu it shorted somehow first time the voltage regulator f** up then the whole board except the module
thanks
👍🏼
will the connection be different in esp8266(esp12e)?
No, same as esp12f
@@ElectroRetro can i get the written code?
@@sheetalprasad5514 which code?
@@ElectroRetro the one that we need to upload in the ide
arduino.esp8266.com/stable/package_esp8266com_index.json
can i use arduino nano to programming esp12e??
Yes
@@ElectroRetrothank you so much, i have done, and it's work😊
Is it possible to program a Arduino in breadboard by nodemcu esp8266
If nodemcu 8266 board have usb to ttl chip then yes. Otherwise you can't.
@@ElectroRetro yes it's have a ch340...
Which arduino board are you using? why you need to program arduino using esp8266?
@@ElectroRetro my Arduino burnt on power delivery circuit...but the atmega is fine...so i want to program it though i need a usb to ttl trying not to buy that...i got a esp8266mod ...nodemcu trying to find it's actually possible or not
Actually I didn't try programming arduino with esp8266 nodemcu, But I think it's possible. Please let me know if it's successful.
can we load code directly without firmware update
Yes
When I press the reset button It does nothing the connecting message keeps saying connecting and it shows the error failed to connect esp8266 Timeout waiting for packet header
Try holding-down the button while uploading a new sketch at the same time.
@@ElectroRetro ok
@@ElectroRetro nothing happened same error message
Make sure your connections are OK and button is working properly.
@@ElectroRetro done i think you told to use one button other videos tell to use 2 buttons and many resistors. So isn't it problem with circuit.

You need to press rst button when it shows connecting and don't forget to connect gpio0 to gnd to enable programming mode.
@@ElectroRetro i did so, but getting same error, can i get ur whatsapp number?
or give me your mail id.

hi
i am also facing same issue
how you fix this issue, can you please share
Sir I don't have resistor can I do something without resistor
No
@@ElectroRetro ok
Isn't there any alternative i have a photo resistor. Any jugad
Do you mean ldr
If you have a LDR. Give it a try. You need to adjust the light intensity to get the right resistance
Can you please tell me how to program esp8285 with arduino
Same as esp8266 programming
why do you have to press the reset button when connecting? Is it okay if you don't use the button?
To enable boot mode/programming mode you have to press reset and boot button. Then release reset button first and release boot button. For normal operation you don't have to press these buttons.
@@ElectroRetro is there another way without using the reset button?
@@ElectroRetro what is the name of the reset button? is there a specific model? I use the reset button connected with a jumper is it the same?
@@alifghifarii8428 it's a tactile switch. You can use jumper wire instead.
@@ElectroRetro okay thanks
Hi iam shadow
😂
I keep getting "Failed to connect to ESP8266: Invalid head of packet (0×00)"
Did you put the esp into boot mode? If you select baudrate of 115200 and put the esp into boot mode it will show waiting for download.
@@ElectroRetro I fallowed your instructions and I put the EN attached to high and the upload speed is 115200. I didn't solder the esp chip, although I checked the connection with a multimeter and it's all well connected with the wires.
@@lyhongleft3676 did you press reset switch?
@@ElectroRetro I did, and I also made sure it worked cuz it blinks too
When you press reset, Does the serial monitor show waiting for download?
Your connections are not healthy. Arduino RX TX works with 5 volts and this is not the same as the operating voltage of ESP. It can withstand this in a short time, but it may not be long-lasting.
