Thanks John!

Thanks Warren!

I’m playing with a Nano 33 IoT. I’m trying to send the state of a push button to Node-RED on a Raspberry Pi. First I started just sending the word “test” to the Pi and that worked fine. But with the button I got nothing until I changed the data type to a char. I guess I don’t really understand the char data type. I tried looking at the Arduino documentation but that was clear as mud. Have you done any videos about char? This project is eventually gonna turn into a home monitor system so I can tell if there are any doors or windows left open in my house. I’m using mosquitto MQTT on the Pi. I also have an Arduino Uno WiFi that is subscribing to the topics. It also has a SIM9000 shield that will send me sms messages when something changes. That’s the plan anyway. One step at a time.

Same here! I started researching a video about the Arduino Nano only to be so surprised at the variety! Kind of neat

Thanks Bart!

Thanks Joshua!!

If I recall correctly, WLED has a setting that lets a node sync to another, so if you set something on one, the others mirror that. That way you can get your desired result without having to set up additional hardware. If you want to build out your home to have more systems interconnected, without relying on a cloud, something like Home Assistant, IOBroker, FHEM or some other locally hosted hub might be a good next step.

Thanks for this Jack! I’ll see what we can put together for demoing some IoT projects.

@@programmingelectronics THANK YOU! You do great work, looking forward to your future efforts!

@@TheJacklwilliams Thanks!

Thanks!

Thanks! Yes,there were a couple others I wanted to add to too, like the Arduino MKR boards and the adafruit feathers

Arduino's version of the Pico has Wifi/BLE

Too much to go into in a reply, but it is really worth learning how. It opens up things like using bare chips, or using little ATTiny85 chips for simpler projects. It is possible to use an UNO or similar as a programmer, and instructions exist for how to do it. Search for things like "using an Arduino as a programmer" for detailed tutorials. The little group of pins at the front of a Nano or an Uno are where you connect to burn the boot loader. It isn't hard, and once you know, you'll wonder why you left it so long.

Great question. I assume you would be planning to use a library like tensor flow lite? www.tensorflow.org/lite/api_docs When you say "all the way", are say training as well as inference, or just inference? If just inference, then yes, I think something like tensorflow lite would work fine. Edge Impulse might be a great resource to check out as well. Best of luck!

Hmmm, I know what your'e saying. Maybe something like this? Adafruit Audio FX Sound Board - WAV/OGG Trigger with 2MB Flash www.adafruit.com/product/2133

Thanks!

I hope you found it useful!

Thanks for watching!

Are you referring to the parameters passed to the attachInterrupt function?

Yes, the parameters passed to both the ISR and the registers are different, the way the timers are set up on the PWM pins is also different.

@@GapRecordingsNamibia I didn't realize this! Are you able to use the digitalPinToInterrupt(pin) for the first parameter to attachInterrupt()?

@@programmingelectronics Yes you are able to use those, but when it comes to assigning the pin parameters for the specific ISR to follow that is where the changes come in. So, this , is still the same (attachInterrupt(digitalPinToInterrupt(but2), heating, FALLING);) But when assigning ISR parameters it will look like this (ISR(TCB0_INT_vect) { TCB0.INTFLAGS = TCB_CAPT_bm; //Clear the interrupt flag) and not this (ISR(TIMER1_COMPA_vect){ TCNT1 = 0; )) Like I said, the timers going to pins 3 and 6 are also different timers.

@@GapRecordingsNamibia I'm following now - thanks for adding this!

Thats right!

By the end of that video I was so sick of saying "Arduino Nano" :)

Ha! Thanks!

Thanks for the recommendation! I'll see what we can put together.

Thanks!!!

Thanks for watching!

Neat! This video was just covering boards made by Arduino, I think the one you are referring is a clone with RF built in?

Depends on where you live! In the U.S. it's "Sodder" all day long; in the rest of the world, "SoLder" is the common pronunciation.

Get a clone lol or better yet get an esp32

Clones are much cheaper
