How to program esp8266 using arduino

[@adiii41]

I spend 8 hours to identify the problem. Eventually I soldered everything to the Arduino protoboard. Now it works :)

[@cristianobudzinski-ud8ee]

I have a question, in your RX/TX interface wouldn't the correct connection be crossed? Rx-tx /Tx-rx? In the video it says Rx-rx/Tx-tx.

[@ElectroRetro]

The labelled TX/RX in arduino uno is atmega328 ic's TX and RX, Its connected to the USB to serial converter ic in the arduino uno. TX to RX, RX to TX. Here we are using Arduino uno's USB to Serial converter IC only.

Nice demo. What is CHPD connected to 3.3v ?. is it labled "En" ? ESP-12F board

[@ElectroRetro]

Yes,It's enable pin(En).

[@anithasshenoy6662]

@@ElectroRetro Thanks a lot.

[@Mureportxd]

Can the esp8266-12f be programmed from the raspberry pi pico w? and how would it be?

[@bazrazin1]

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.

[@ElectroRetro]

Yes, You can use ch340g board. Don't forget to put the jumper to 3.3v.

[@s3ht]

I have Esp12e and Uno. Do I need anything else other than a 10k resistor while doing this?

[@ElectroRetro]

It would be good if you have 2 tactile switches.

[@alifghifarii8428]

why do you have to press the reset button when connecting? Is it okay if you don't use the button?

[@ElectroRetro]

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.

[@alifghifarii8428]

@@ElectroRetro is there another way without using the reset button?

[@alifghifarii8428]

@@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?

[@ElectroRetro]

@@alifghifarii8428 it's a tactile switch. You can use jumper wire instead.

[@alifghifarii8428]

@@ElectroRetro okay thanks

[@alifghifarii8428]

Can the multimeter be replaced with a battery or power bank as an external 3.3v power supply?

[@ElectroRetro]

Yes

[@martinromano99]

Did you have to use another adapter before connecting the module to the arduino?

[@ElectroRetro]

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.

[@martinromano99]

​@@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..

[@martinromano99]

@@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

[@ElectroRetro]

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.

[@thisisthanish]

​@@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

[@drawcraftwithshubh116]

can we use arduino nano

[@ElectroRetro]

Yes

[@alifghifarii8428]

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?

[@ElectroRetro]

Do you have flyback diode connected to the relay? If yes, then it may be electromagnetic interference from relay.

[@alifghifarii8428]

can a flyback diode fix this?

[@ElectroRetro]

@@alifghifarii8428 it may fix.

[@alifghifarii8428]

@@ElectroRetro I've used a flyback diode and soldered it to the relay but still can't fix it, is there another solution?

[@ElectroRetro]

Place relay further from ESP. That may work.

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

Is it possible to program a Arduino in breadboard by nodemcu esp8266

[@ElectroRetro]

If nodemcu 8266 board have usb to ttl chip then yes. Otherwise you can't.

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 you please tell me how to program esp8285 with arduino

[@ElectroRetro]

Same as esp8266 programming

[@ismail_aydemir_youtube]

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.

[@profy2002]

Thank You !

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
