Tutoriais de Programação e EletrônicaAltimeter code: Page 4, downloading flight logs over WiFi
Copying a thousand lines out of a terminal window is fine at a desk and miserable at a launch site. This altimeter records at fifty readings a second, saves each flight as a CSV file in the chip's flash, keeps the last five, and becomes a WiFi access point the moment you plug it…

Page 2 gave you one number. This one gives you the whole flight. It records the height ten times a second, keeps three seconds of readings from before the launch, and works backwards through them to find the exact moment the rocket left the pad. The flight prints as CSV over…

Tutoriais de Programação e EletrônicaAltimeter code: Page 1, introduction to DIY rocket altimeters
The Mercury V1 is the one altimeter we leave unlocked on purpose, so you can put your own code on it. Part one takes you from a bare Arduino IDE to a working barometric altimeter that prints pressure, temperature and height five times a second, and turns its LED blue when you…
