excellent video! thank you for this one, it had everything i was looking for and no bullshit around it. im subscribing.

I want to send an 1800 element 2 byte integer array between two ESP32s in close proximity. One will be in a steel box and so I guess that I need WiFi with an external antenna. I do that with an internet radio and it works fine. I do not know if bluetooth could use that or would it be locked inside the box. Would ESP-NOW be a reasonable tool to do this with, either on WiFi or bluetooth? To be clear, I currently send this data from a PC to one work ESP32 using a USB cable and normal serial comms, but I want to change to wireless connection. The PC software is all set to do the serial comms so I am thinking of adding a second ESP32, connected to the PC as a WiFi "dongle". Thereby the PC will work as before but sending to the "dongle" and then I want the "dongle" ESP32 to send the data on to the work ESP32. So my array is way over the 250 byte packet limit at 3600 bytes but I currently send that as 1800 separate 2 byte values over USB and could happily do that with ESP-NOW if it is a sensible way to do it. Or I could break the data down into 15 smaller arrays, but that is messy. Transmission time is not an issue so if ESP-NOW wanted a rest between packets it would not be a problem. Otherwise, do you have any other suggested protocol? BTW I have only just discovered your channel and I like your extremely clear mode of presentation.

Absolutely yes, thank you. People like yourself make it easy for us to build project in a much shorter period of time. In my case I want to use the rf modules to keep two Arduinos in sync whilst controlling two sets of addressable LEDs

Isn't the selectable voltage of the ZY12PDN a little dangerous for devices that can't handle higher voltages?

Can the same power supply be made with a buck boost converter module???

Great video and love your workshop. So informative and I hope I can provide the same level of information in the future. 👍🏾

I wish you would have shown the esp32 files that is easily downloadable from the board manager. It has all esp32 in it.

Something you didn't mention was that both the right and left joysticks also work as individual buttons, L3 and R3 respectively.

thanks

Everything I've read says to avoid using strings on Arduinos and to stick with fixed size data structures that don't cause memory fragmentation. What's your take on that?

Van I use the pi camera to inspect pcb board .. like to verify resistor values? Cap placements. Etc.. etc...

Excellent experience with all yr projects.

Hi DroneBot, what is the brand and model of the 240W USB PD Charger with the digital display shown in your video? I'd like to purchase one as well.

Article with all the code: - "Oops! That page can’t be found." ... found end of the link must be changed - "esp32cam-robot-car"

Enjoyed this hands-on video!

hey i have been trying for weeks now to program an esp32 wroom to play music via bluetooth and when ever i connect to it via bluetooth it disconnects i have no clue whats happening please help

Bonjour, je suis un débutant dans l'utilisation de esp32 et je me suis perdu dan Arduino ide. Votre démonstration est encourageante et va beaucoup m'aider. Merci!

why are you not showing the DS18B20?

This is too cool. I bought a 433Mhz set similar but not exactly like the one you used. No documentation with components and I had no idea how to use until today. Thank you for this great teaching video. Hope you're doing well.

Very interesting! Curious why can't this be done on modern laptops [internally], if in fact with an add-on CAN and has been done for gaming smartphones [done so externally due to limited internal volume]?

I just built a VPD calculator using a mish-mash of other projects (although I ended up rewriting most of it) by using a DHT22 and doing a calculation on temp and humidity to tell me where I am and where I need to be for optimal growth. I managed to do that and now I think I know enough about how it works that I think I can make my extractor fan start and stop to meet specific VPD target ranges. I am waiting for the solid state relay as we speak! This looks really cool, I might experiment to see if it can be applied to my use case! Great video :) I have been watching you and Paul Mcwhorter a lot this past week, had an arduino for years but never got over the initial coding learning curve until now. I still get hung up now and again. I wanted to use an interrupt to make dimming on my TFT more responsive and it felt like I was back in day 1 again xD Ps: I would imagine that the light reading is in umol/s, more commonly referred to as PPFD

Loved It.👏

Thanks

Great to see that you are producing new videos again. Very much looking forward to your this one as I am experimenting with the creation of a new ROS robot and I am totally new to Raspberry Pi

is it possible to control the direction using only 1 pin per channel?

You are a very kind and nice person greetings from Sydney

I like the online alpha manager and online 'esp tool' (or offline python version) BTW, not mentioned, but what about debugging? For example, isn't the biggest advantage to the single-core Risc-V options (C3, C6) is that it has a built-in debugger... whereas the dual-core/bluetooth S3 requires an external esp-prog JTAG adapter? Would love to see how to debug and single-step on C3/C6 and s3 using VS Code and PlatformIO. BTW, I understand VS Code + IDF Extension you need to first install IDF VS Code + PlatformIO Extension, you don't need IDF nor IDF Extension but aside from the different build-systems, what is the difference between VS-Code developing/debugging using IDF versus using PlatformIO?

😃

You are the best!! Bravo!

Can we use wifimanager with telegram bot? Anyone do some like it?

Thank you very much for the video This was a very helpful video about Op-Amp I really enjoyed the video

Quality video. Thank you for making it and sharing.

Can I program an Arduino as an ISP, to program the Atmega through SPI?

i saw hakuna matata on of the wifi a swahili word from East Africa, proud to see that 😁

I use a custom board that uses an atmega1284p as the main microcontroller and esp32 s3 for IoT access. They can be both powered and flashed separately but the default firmware of the s3 is set for OTA updates and IoT. For me, what i don't like about the s3 is it can't operate both bluetooth and wifi at the same time. It performs very good, basicalky the best of both worlds.

exactly what I was looking for. Great Video, keep it up!

Actually there is a few other functions meters do Micro Amp NCV Live detection Phase Rotation Transistor test IR température Thermal Camera Lux Meter DB Meter The 5 last are very rare. But they do exist. Also there are ways to add a clamp in some models...

Great

Alex from Germany, thank you so much for the video. Searched my brain out to find good content to this topic. Keep up the good work :)

How you got 24 fps?

great video

Loved It.👌

a ton to learn, have plans of getting one, plus upgrades, lol can my brain relearn all the tec? idk, but willing to try.

infact this has spoilt my interest now another time maybe

your title is worded more like an ADVERT than a content vid. I normally just click do not recommend for such videos. Lucky this time i check but bare it in mind cus that is my normal ploy

I was wondering could possibly that psu being used on Baterrys? I mean preciseli Using car relays to power as input to that PSU or directly used alternator HV DC supply and use that ATX to run smaller cirquets and sensors? I'm not Shure how much I know 12v relays produce Kinde of Dc flat line to DC pulse so using 2sets of 5pin dual relays you should probably get virtual + and virtual - electricity ? So I believe It could by done how ever there should by some neutral relay as well so case would not shock some one .Just my silly thoughts . So I was wondering how much those components need pulsed DC amps volts to saftly operate ? I'm refering to the out put DC rectification cirquets who powers the ics and transistors how much power do they require?

Hi sir, can we use PMS7003 in stead of PMS5003?
