Great video! 👍 ESP32's are awesome boards. I designed a car Bluetooth radio based on one, I also monitor and control my temperature control system in my 3D printer cabinet with one. They are very versatile devices with a lot of capabilities.
That’s absolutely incredible! I’m working on using it for a techno-teddy 😁(for my next creative engineering project/video) but I’m still working through a few kinks with getting the audio amp module, 2 OLED displays AND a 3.5” TFT LCD module with micro SD card to all run off it, while also connecting it to a Li-Ion battery and 3D printing the compartments /containers for everything. I’m probably going to need some power modules to aid the current being drawn from it.
@@techwithrita Very cool. I have no doubt you will figure it all out and your project will turn out awesome. For my temperature control system, I thought about using an OLED to output pertinent information... I decided to have it serve a webpage to my local network where I can monitor and control everything. I also ran into some power delivery issues powering the ESP32, 2 relays, a servo, two fans, and an LED bar. I ended up creating wiring harnesses and am powering all of the devices off of 3 USB ports and have a standard (wall plug) battery backup for the whole system. The wiring was/is pretty intense on this project, but using a lipo/lion battery and wiring directly to that would have simplified my wiring conundrum. My next project, I will definitely be using a lipo/lion and implement charging circuitry for the battery.
Nice video about Seeed XIAO ESP32 C3 👍. The possibilities are immense with these little boards... I just bought one of these boards thinking about developing a simple version of the flipper zero, but with the ESP32 S3, the size is excellent and as a prize it even includes a chip for battery management, this will be very fun 🤭
Yeah I agree, but some Chinese lighters have an LED without current limiting resistor with 3 small batteries and it works just fine. But in this case 5v yeah it should be necessary.
Some good advice here...I haven't tried one of these small boards. After this I'll do some reading and pick one up. Wow...TinyML capable..Very Interesting! (XIAO ESP32S3 Sense)
C has to be interpreted as well. Python is just a higher-level language compared to C. Much like a scripting language. That is why it takes up more space, runs slower and has more to interpret before getting to machine language (which technically is binary) but there is a language that is used before that, which is Assembly. Thats what compiling does, it gets the "more-human-friendly" language, down to something the hardware can use, along with all the fun hardware specific stuff. Also, the resistor isn't always just to protect the LED, which in most cases you won't need one if you are just running the board off a USB port and a single LED on an output pin. The second use for the resistor is as a Pull-Up or Pull-Down resistor and you should ALWAYS be in the habit of using these. Otherwise, you can leave your output floating. It's very easy to use one, just connect a 10k resistor from the output (The output pin you set in Arduino) to a ground, and this will tie the line LOW when not in use. This will stop it from floating and its good practice because not all hardware has internal Pull-Up or Pull-Down resistors. PS. your video wasn't horrible, most of the female tech videos are, facts....
was looking for the battery charge/control functions but good vid

Thank for this been tearing my hair out over this programmed it once then could not reprogram it now I can thank you again.
Did you find any way around for entering into bootloader mode? Pressing those small buttons every other time sucks.
What's best way to step down a 5v signal from a sensor to esp32 input and make it 5v output signal again to the receiving device?
You really should always use an current limiting resistor with an LED.
Yeah I agree, but some Chinese lighters have an LED without current limiting resistor with 3 small batteries and it works just fine. But in this case 5v yeah it should be necessary.
It's to protect the pins of the micro-controller (mC), usually they can't drive much current, if you don't use a resistor the mC can be damaged 😢
can you do a video on the soldering process please, i have the headers but I'm scared to mess it up
I soldered the pins to my four Seeed XIAO boards and I swear I prayed they worked well because I used a very large tip compared to the pin spacing 😂😂😂
How long do you need to hold down the boot

Nice.
😍
Es una lastima que no tenga el bluetooth tradicional que mucho mas facil configurar que el ble
