@lupyuen they are amazing for teaching and just hobbyists in general. I have a pile of them i throw on pretty much every project to have a bit of a readout even if just for debugging.. their amazing, they are so cheap their almost free :)
Its a big step up from when i got started in the 80s with the Vacuum fluorescent displays that cost a noticeable chunk of change (especially to a kid) and couldn't even output english letters half the time, just numbers.
Attached one for reference in case anyone reading this doesnt know what they are.
@freemo Haha that really shows your age 😉 (I'm that young either!)
@lupyuen LOL it does, though keep in mind I was doing electronics as a hobby since my age was still single digits.. I was soldering by 8 or 9
@freemo Haha that's precisely the point ... We should use these Low Cost Displays for teaching IoT!
BL602 has so much RAM anyway ... Time to do away with the old style Arduino gadgets 😉
