I’ve got a dead simple toy I’ve built with my Electron. Literally it’s a button press that sends an email. I’m doing everything I can to save battery consumption so I’m putting my Electron to sleep with the following:
I’ve got a perma proto all soldered up and installed in custom chassis I’ve printed. It’s working wonderfully. Flawlessly, even.
My build is missing a feature though - a light to let the user know their input has been received. The chassis its in is solid black, so the on-board LED is not visible. And since (as far as I know) the Electron has to run through the wake-up process and get itself all comfortable before it executes any code, there’s like a 15-second delay between the button press and the activation of an LED. Which is basically the same as having no LED at all.
So how can I:
- Maintain battery conservation
- Turn on an LED during boot, OR
- output the on-board LED’s activity to an external LED wired to the board?
Any ideas? I’ve put this in the “firmware” category in case somebody can think of something I can do in the firmware to turn an LED on. If it’s miscategorized, apologies in advance.
