Thanks Ron, I only said yesterday that maybe PlatformIO is bit too much to handle & luckily, the course I’m doing does allow you to use IDE 2.0 so...
@zander Thanks Ron, I can see the examples but they seem to refer to arduino shields etc. " sample for SAMD21 running WiFiNINA shield" for example...
Thanks Dave and others. It may have been IoT cloud which means it won’t be good for my project which is on a farm away from the Internet. Project is ...
Hey Bill! You have a circuit showing an NPN transistor. You show 2 choices to use. A 2n2222 and a 2n3906. BUT the latter is a PNP type. I am guessing ...
I would prefer not to have to learn another platform so I'm happy to see your Pi 4 videos and refer to them in the future.
Update. Looks like I spoke too soon. With the pins around as original, the 433Mhz transmissions wont work but the Ultrasonic sensor does. Visa Vers...
Oh Dear! How utterly embarrassing. I found the problem. I made a copy of only the Radio 433Mhz code that works with the DHT sensor. Slowly I adde...
Thanks to all for your replies. I think it’s best if I summarise what happened BEFORE I started hacking / adding code. Code from the Drone Wor...
Thanks Ron. I'll check but the original code without msg1 worked without issue. So I have not tampered with that section. I'm still highly suspici...
I have an update. My edit window just expired after pasting code and photos. The sketch compiles and uploads without errors. It's the behaviour o...
It should be possible to use an opto coupler (opto isolator) like a 4N35 to translate and isolate the split signal to a 0 to +5 volt signal. The opto...
Gidday. A lot of electronics beginners get trapped with these linear regulators. You may be surprised to find how little output current you can supp...
