    This is exactly what I've been needing for a project that I've been struggling with. There are other tutorials online but none as concise as this one. You've really struck a home run on this one! Thanks!
  • @klif_n
    This has been very helpful in getting me started with ESPNOW! Thanks.
  • Thank you. Very very helpful. So many creative projects are curating in my head right now. I remember taking c and not understanding pointers very well. I’m glad you walked through that portion.
  • I'm going to try this out tomorrow I have had an idea for a bit and this gives me the basics to get it done thanks
  • @antextra300
    By far the best teacher of all things Arduino!! This video helped me so much!! Most other videos do not explain esp NOW in a way that I could piece apart and use. But you did! Thank you so much!
  • Great Video, I just got 3 ESP32 and made your simple program and it works great
  • This is an awesome explanation of something that I have struggled with. I agree it opens a lot of doors for remote control and sensor data transport. Not having it on my network, or having to rent online "cloud" space makes this a winner. Thanks for making it easy to understand!
  • @u2bist
    DUUUUDE! This is the best, clearest ESP-NOW intro video I've seen, exclamation point! Your explanations are super easy to understand, and taking the time for code cleanup to clarify the examples was awesome. And yes I totally agree ESP-NOW is a very underused platform more people should take advantage of, which is my goal. I can't believe I haven't been aware of your channel until now. SUBSCRIBED and looking forward to checking out more - Cheers!
  • Thank you so much for this! Easy to understand and follow!
  • @gazzacroy
    man what a brill video. i've been using esp now for just over a year and never totally understood how it works.. man this really help me to understand more.. brilliant.. :)
  • @sennabullet
    Superb. By far the most comprehensive and most easy to understand explanation of the ESP Now protocol on YouTube. I am incredibly grateful for your effort to make this video and share your knowledge.
  • Great video. I use ESPNow to send BME 280 data from my solar weather station to a receiver located inside my house. The receiver then sends the data to Blynk. The connection/awake time for the solar weather station using ESPNow is less than using WiFi. A definite plus when powered by a battery.
  • @morpheon_xyz
    This is exactly the kind of information needed to kickstart some badass projects that require wireless transmission between 2 boards. Definitely planning on using this information in a few projects as this will be an amazing way to control things over a short distance without having to use any form of internet or additional modules to make it work. By the way, that's one badass project you've got there. It's simplistic, yet really cool and functional as well. Sparking some awesome ideas by showing the basic concept of possible uses for this wireless communication feature built into the ESP boards
  • @Indoseraya
    This video really help me to understand ESP32... great
  • @fggolding
    Excelent video, it could not be better.
