- In this video, we are going to be using the Arduino Xiao board and build a thermometer with it! We are going to use an OLED display and a DS18B20 Sensor.

I hope you took away lots from this video and you managed to get your Xiao to work. Let me know below!

This still works
It's good to see you back in action again. I missed your excellent videos while you were away.
It has been a long wait for your excellent tutorials.... Keep up the excellent work
Thank you for bringing these micro controllers to our attention, I just bought a pack of 3 to try out.
You have no idea how happy this makes me. Still works in 2023 with updated arduino software.
Cool! I am really glad it made you happy! Mission accomplished! ;-)
Great product
Nice walkthrough
Thanks for sharing😀👍
Welcome back!
Super video!!! Thanks for upload
I'm currently going through the Elegoo Uno R3 tutorials on my channel but seeing the size of this thing makes me want to switch. Perhaps in the summer I'll get this, thanks for a great video.
It does support 5v. The power pins are 5v - Gnd - 3v3. The 5v pin output is the first pin next to the led's.
I love your voice. Plus, that's a really good video
Xiao (小) means "little" in Mandarin/Chinese
Πολύ ωραίο!!
Efharisto. Please, write something about deep sleep modes of Xiao, its interrupts and how to play with them.
On the Seeed Studio site they sell this for $5.00. They have also developed ArduPy a combo of Arduino and Python. Please check it out and consider doing a video on it?
Hi...Have you tried it(xiao), without led? , in running and sleeping mode ?... Any know if you can use rtc, by direct programming in your flash? ...thank's
When you power the board through 3.3V pin, does it also charge the battery if the USB is plugged in ? Or does it have to be plugged at the back at Bat+ and Bat- ?
Hi! I just would like to ask if the GSM sim900 can call at the same send texts?
What Program are you using for the schematics?
Very nice video👍👍
It's crazy how much ram that has compared to the Uno R3 😂
Can seeduino handle more than one circuit module
hello, i would like to ask. is it possible to use this for IoT?
Good to see you again! With the Seeed board plugged into a PC, does it drop the USB 5V to the 3.3V required? Thanks & great tutorial! 🤓🙄
Yes of, course. It has a regulator which takes in 5V and outputs 3.3V
@@Educ8s ok thank you 🤓
It's first pin next to the led's are 5v - Gnd - 3v3. It will power modules requiring 5v from that corner pin. The two corner pins next to the USB C plug are not labelled on the sticker due to the size available and also the chip cover doesn't allow for the sticker to line up with the first and last pins. Try a multimeter on the power pins rembering that the ground is in the centre of the 5 and 3.3 volt pins.
@@stevetobias4890 ok thanks 🤓
Is the library removed? it is not there anymore
The title is slightly wrong! Actually the arduino the smallest arduino board is the arduino PICO, what is roughly 1.52x1.52cm.
This one is still really small!
You are right! I changed it! Cheers!
There is No EEPROM, is there a way to save data before power down on this controller ?
Love your Chanel. Very interested in this board. Got a load of projects that don't require fast processing butt require accurate analogue input measurement and digital / relay outputs. Is this a good choice?
Look forward to possibly using Python?
I think yes. Check the SAMD21G18 datasheet to see if the resolution of the ADC is enough for you. Python works, but it is slow in this board, and the RAM is barely enough.
@@Educ8s Ok Big thank you!
@@Educ8s Yeah, seeing the specs (RAM and flash) I thought running python (micro- or other flavour) might be a bit of a stretch. Too bad, for my hobby projects I've completely switched away from Arduino to Micropython.
Fun board though for low power/small size applications.
I had to copy the URL by hand and didn't work
If I have a 5v power from an ESC of a rc car, should that be ok? If not what should I do ?
The Xiao has a 5V VCC Input with an internal voltage converter to get 3.3V.
Any idea why LED_BUILTIN, HIGH and LED_BUILTIN, LOW are reversed in the Xiao ? High turns led off and low turns it on.
Hmmm, I didn't notice that! We should email Seeed who creates the board to fix this! Thanks for letting me know.
Cool little $5 computer
How do you put this MCU in Sleep Mode???
the processor these use implement the cortex M0+ isa, which has WFI and WFE instructions that put it to sleep pending software or hardware events. The arduino studio SDK contains examples and a library called "EnergySaving" that use these.
1mA in sleep mode is actually waaaay too much. In my opinion this is a common problem of most available dev boards, even the original ones by sparkfun and adafruit. Why place chips that have fancy sleep modes on pcbs that have high quiescent current? I don't get it.
Yes, it is much but I didn't remove the power LED which is ON all the time. If we remove it, we can reduce the power draw to about half I think. Other than that you are absolutely right. Why is it so hard for a company to develop a board that use the deep sleep capabilities of modern chips? This is something all makers want, not just more speed and FLASH and RAM.
ok
Υπάρχει μια μανία με τις οθόνες παρατηρώ! 😅
;-) Με έπιασες!
