YOU can Learn the ESP32 in 15 Minutes: Hello World!

An introduction to developing for the ESP32 Microcontroller. Dave explains how it relates to the Arduino line, how the specs compare and takes you through the basics of a Hello World application for the ESP32.

I found your channel 3 years ago and have been a fan ever since. I started with the ESP32 board with the OLED you used teaching us to display information and designs on it and I was hooked. Have made many projects with addressable LEDs, WLED, remote sensors, all because of you. Thank you again.

Really appreciate you doing this series on ESP-32 with all the details.
Would love to see this series continue and cover both basic and complex functions, hardware and software.
Thanks Again Dave!

Just getting back into esp32s after a few years break, Great to see how things have moved on. Looking forward to the rest of the series

It's great to listen to someone at this level of knowledge finally. Not slow and boring.

I just discovered you in April 2022 and a newbie at coding (completed 70 hours bootcamp Javascript) and I really like your channel, so thanks for your great content and being so positive.

I have found my new favourite YouTuber! Taking it step by step ☑️ Getting to the point ☑️ Editing the slow bits out ☑️ And being very funny along the way "319ms, I'm a busy guy and that's pretty good"... massive tick! ☑️

Dave, I've just found your channel and have to say it's absolutely brilliant. You are an excellent host. I love your content, and especially your delivery - which is first rate. Looking forward to going through your older videos. I'm sure there are some absolute gems in there!

This is a great video - I get lots of people trying to use my projects who are very inexperienced and don't know how to build and upload projects - this will be a great resource for them.

[alexhutchison]

Would love a continuation of this series. Love the videos.

[mikemontana]

Thanks so much for including the "oops" - like the baud-rate mismatch -- you saved people hours by including details like that!

@Dave: I find when I talk to people that describing the ESP32's standby in terms of battery life helps drive it home. The ESP32's idle is roughly 10% the self-depletion rate of an 18650 cell. That is to say that an ESP32 on standby for a year, powered by an 18650 might have 30% state of charge, and 7% out of the 70% battery capacity lost was used by the ESP32's standby. So implementing an SCR to allow it to fully power itself off is a waste of time, since the SCR will consume more power than that by way of voltage drop during operation.

I've been using ESP32 devices (as I suspect a lot of people have) with Home Assistant and it's great to see an intro to programming on these. I didn't know about the serial monitor in VSCode - that's a real bonus. Thanks for this video and I look forward to more videos on the ESP32 as I think it's a great little microprocessor. Cheers 🙂

This episode is one of my favorites. You are so genuine in your enthusiasm about the ESP32, Its fun to watch you go through the process in realtime. I miss that quality in your newer stuff. Thought still great, this hobbyist level stuff is what I really enjoy.

[cdoublejj]

as a non programmer (i tried learning C++ numerous times) and home assistant user looking at esp32 this was VERY informative, i almost understand some of the programming stuff too.

[edwardandrews]

Great, quick video to get me re-started on ESP32S. Things didn't work well for me, however, as I had an older ESP-32S (bought several years ago) and it suffered from "CAN NOT CONNECT" errors when trying to upload. If anyone else has this problem, try this fix which I found elsewhere: Add add an electrolytic cap (2.2 uf to 10 uf) from EN pin (+) to GND (-); this fixed things for me!

[jcugnoni]

The ESP32 is a wonderfull coding playground indeed ! Great introductory video.

[olafzijnbuis]

I like the way you align the {} brackets at 12:42
Code looks much better and easier to read when all brackets are nicely aligned.
The way it is done in Python and Occam is even more elegant.
Nice video. It helped me to move the code for my 8 x 8 x 8 RGB LED cube to Visual Studio Code.

I've built an awesome smart device for my wife's business around the ESP32. I even designed a full PCB and all the parts, traces, connections etc to run. There is a smart phone app that pairs with it. Runs 7 - 120v motors multiple 5v fans and devices and a few 3v items. Super fast and simple. Esp32 is an amazing piece of technology.

Just found your channel and it is exactly what the doctor ordered!
After decades of being a serious woodworker hobbyist, I caught the electronics bug this year when I put up my first exterior WLED Christmas lighting system. It got me hooked.
Now, I am migrating the woodshop to electronics shop! ...wanna buy a nice 8" jointer? :)
