Several Chinese words that pronounced xiao: 小 : small 晓: know something 孝: be good to one's parents 笑: laugh 校: school 啸: shouting out loud 消: usually vanish, e.g. 消失 xiaoshi 宵: night time 硝: saltpeter 削: shave something with a knife 枭: usually an owl 哮: roaring

I automatically thought it was probably small.

That's why Chinese characters exist. Romanized Chinese words all look the same. In addition to Barack's list, here are some more Xiao's for daily uses: 效: effectiveness 销: sell 肖: portrait 淆: to confuse 箫: the musical instrument mentioned in the video 霄: sky 嚣: noisy 骁: brave

[@taobaomaicai8592]

As a Chinese, let me tell you what Xiao means. Xiao can mean small. This board is so small, Xiao means small, I think my understanding should be correct.

[@gordslater]

27:40 to tone down an LED output for photography / filming, three quick methods: Sharpie - dab a sharpie on the LED. The ink can be cleaned off later with alcohol on a swab. May require a couple of applications 20 seconds apart to build up a blob of dark ink over the emitter. Nail varnish/laquer - use an opaque neutral colour like (nonmetallic) grey. This is permanent. Works best if you place a drop on a hard surface and let it partly dry before transferring to the LED. Correction fluid (WhiteOut/Tippex) this is extremely messy and permanent.

[@TechProbe]

Hello !, I appreciate your tech contents, I like your clear English pronunciation to comprehend easily as a foreigner. I am not a Chinese but Xiao (小), a Chinese character means small, tiny, mini,...such as in XiaoMi (pronounced Xiao also has many other characters having other meanings though) . So I guess Seeeduino XIAO was named from it.

[@Enigma758]

5:47 Can't a single interrupt routine be used for both pins if the first thing the interrupt does is to check both pin states to determine which transition caused the interrupt and then branch to the appropriate handler code?

[@JonathanDeWitt1988]

Bill, This is a very exciting microcontroller. It's capabilities in memory and processing speed versus the standard Arduino are impressive. And for a much cheaper price and size factor as well! My thought with any new microcontroller that outperforms the Arduino has always been that they don't have the documentation (educational material) out there like the Arduino Uno has. Your point in this video about a lot of the code from the Arduino being compatible with the XIAO makes the XIAO leaps and bounds above the rest of the microcontrollers that have been introduced lately. A XIAO tutorial series like Paul McWhorter's New Arduino Tutorials still wouldn't go amiss. It wouldn't even have to be as developed as that to launch the XIAO off. It could just be short videos showing differences between using the XIAO for that video versus the Arduino Uno if there are any differences at all. Thank you for introducing us to such a promising and interesting new microcontroller. As always I enjoyed your thorough explanation of everything you put up on the screen. I didn't feel rushed and like I had time to absorb what you were teaching us.

[@scottiusnevious5143]

Shouldn't the peak-to-peak voltage in the sine wave at 33:30 be closer to 3.3V? It's much smaller!

That is because the sin function expects the angle parameter in radians, not degrees

@@jonasmaugust True. Maybe the external connection between DAC out and ADC in was missing? Note there was no wiring diagram animation to show the wiring. I don't think this will work without external connection.

[@jonasmaugust]

@@MrMartinB1962 At 24:31, breadboard rows 27 and 24 are connected by the yellow wire, so pins A0 (DAC out) and A3 (ADC in), but the Arduino sketch sets A4 as the ADC in. That would mean the plot is of a crossover voltage from A3 to A4?!

[@MrMartinB1962]

@@jonasmaugust The frequency is also wrong. With an increment of 0.02 the cycle should repeat every 314 iterations. There should be just one complete cycle between 0 and 314 iterations but at 125 we already have about 18 cycles. When I continue the rough math: 18 cycles in 125 samples means 6.94 samples per cycle. the serial plotter shows a total of 15136 samples in about 36 seconds (according to the video time). That comes down to 2180 cycles in 36 seconds which equals 60.58 cycles/second. Roughly 60Hz, it's just mains hum on an open ADC input.

It seems to be a versatile board, but obviously your have to make some decisions before using it, since the pins are double or triple-duty.

[@isidronilsson5804]

Love having you back. You must spend countless hours rehearsing for these videos. They are so well thought out and perfectly executed. OK, enough for the accolades. Now my question. I am trying to measure and monitor a voltage between 0.1mv and 5mv. The arduino uno does not seem to be able to measure less than 4.9mv and not sure how to use the internal ref that would let me measure lower voltages. Is there a simple way to measure 0.1 to 5mv range? Perhaps the seeeduino xiao?

[@connerblah]

If you need a high resolution reading of that range, you'll probably need an amplifier circuit. For something that low I'd do it anyway. Then you can use whatever microcontroller you want!

[@a_commenter]

1:35 Xiao is also the Mandarin word for "small", which probably sheds some light on why they called it that.

Good stuff... does the temp sensor need a separate pull up? I thought most processors had them integrated. Also check out the Adafruit version of this - the QT Py. Same form factor, similar price, but proper reset button, RGB led and a ‘stemma’ i2c connector on board.

[@CPLBSS88]

thinking about using this to control and power a RCWL-0516, possible a PIR sensor, and some sort of a transmitter... leaning towards a COTS 433mhz transmitter for simplicity... basically building an outdoor motion sensor. The RX side will probably be an Raspberry PI that displays an led and vibration for alarms... do you think this would be enough for the sensor side control?

[@brendanowen7563]

Another great video. Thank you

[@agsystems8220]

You should probably point out that the major difference between this and arduino stuff is that small circuits can be driven directly by the arduino. I highly doubt you could pull 40mA out of one of those pins safely. For many purposes you will need to have drivers for everything anyway, and this would be ideal, but for small scale tinkering arduino is a more self contained solution. It is possible that these are relatively fragile too. The lightweight board may lack protections, making frying it while playing about more likely. For playing around I'll stick to arduino, and for production a custom board is probably warranted. A nice product, but not a competitor to the arduino. It does something slightly different. The potentiometer not going down to 0 is not a bug. Maintaining linearity all the way to 0 ohms would be extremely difficult, so the voltage will never reach ground.

[@danblankenship5744]

Thank you for introducing us to this power-house. I see that they are becoming rare and the price is climbing, so I just bought 10 boards. I wonder if my OLEDs will work or do I need some level-shifters? I see it's easy to drive an LED so I wonder how much current a pin can source. I see they have additional development and wireless boards available. Are you going to explore those too?
