ESP8266-01 board has I2C communication?! || Exploring ESP8266:Part 1

Hello everyone! Thank you for stopping by my video!
This is a very exciting video about the almost forgotten ESP8266 01 Wi-Fi modules. These modules are very much used to have a Wi-Fi feature in standalone Arduino projects but with more powerful boards like the NodeMCU and ESP32 in the market, this board is now often ignored.
Join me in this mini video series where we explore the various powerful but rather unexplored features of this little board.
In this video I show you the I2C communication protocol and display data on an OLED screen that is commonly used in several electronic projects by hobbyists.
You can find more details for this project here: www.instructables.com/I2C-Wit...

Hi, good explanation! One question: can I use LCD1602 with PCF8574 like I²C bus?

[@syaduinotech3681]

Thanks for your exploration. U open up my mind. Suggest to share video/ explore the use of i2c with sensor your part2 and perhaps with simple data sent to server/ clouds. Tq sir

[@UtsavShah_25]

Thanks for your feedback! Glad that it was helpful. I have made a video where I have exchanged data from cloud server. You can watch part 3 of this series to see how to interface Blynk plaform with this setup

[@chandraprakashmaurya3924]

I'm getting noise all over the display and behind the noise the text is barely visible which i wanted to print , do u have some suggestions to solve this issue ??

[@jensschroder8214]

7:34 OLED_RESET; is extra Pin to reset the OLED. But you have no Reset pin.
7:49 Wire.begin(2,0); setup I2C to GPI2 = D4 = SDA , GPI0 = D3 = SCL

Nicely explained 👌

I guess im randomly asking but does anyone know of a method to get back into an Instagram account?
I stupidly lost the login password. I appreciate any tips you can offer me.

@Calvin Damon i really appreciate your reply. I found the site on google and Im in the hacking process now.
Looks like it's gonna take quite some time so I will reply here later with my results.

very good

WOW!, i didn't know that!, Thanks!

Welcome! Glad it was helpful

Can you please give manufacture you use for the ESP8266-01 BOARD? Great Video!
Would this ESP8266-01 WORK WITH Raspberry Pi Pico too? M

[@UtsavShah_25]

Hello I am yet to interface it with Pi Pico, would surely give it a try!

[@michaelcarroll4832]

@@UtsavShah_25 Hi; Please let me know when you show a video?
Which ESP8266-01 BOARD are you using for this video? Thank you!

[@Mr_ToR]

If you first program the esp01 with a blank OTA firmware (over-the-air) you won't need to physically connect it to your computer to develop, edit and upload. You can just send the new firmware over the air.

[@UtsavShah_25]

That's a great suggestion! I see how this can be useful in minimising the hardware requirements. Would be great if you could share any article/video on how to implement this OTA feature. Thanks!

[@ChadGatling]

I can't get this to work. The OLED does nothing.

[@komalthakkar3681]

Hi dude 😋

[@Brian_Of_Melbourne]

I'm not sure about your schematic. VBUS isn't connected to the input of the regulator and pins 1 & 2 of the four pin header are connected together shorting GPIO0 and GPIO2.
Your assertion that the ESP8266 works at 5 Volts may be true for you, but in general this is not true. It should ONLY be run at 3.3 Volts.
While the Adafruit OLED does have an onboard 3.3 Volt regulator and appropriate level-shifting this is not generally true of all display modules.

[@UtsavShah_25]

Yes I agree upon what you said about mismatch of voltage levels. That being said I would highly recommend you to watch one of my previous build which is making a development board for the ESP8266: I've named it as ESP-O-One. The main circuit diagram is comprehensively described there and the ESP is powered from 3.3volts.

[@ds2kx]

Same materials, connected just like you...used same libraries, use same exemple. Not working.

[@saylus21]

Fake 😑

[@saylus21]

You Don't show that screen is connected to sca and SDa. So how we can believe this.

[@UtsavShah_25]

@@saylus21 follow the schematics and try it for yourself.
