==== Váhy s ESP8266 ====

**OTA programování**\\
http://milansrajer.cz/ota-programovani-esp8266/

Zajímavým způsobem programování ESP8266 je tzv. OTA update. To znamená, že upload softwaru nemusí probíhat přes kabel, ale bude se tak dít jednoduše „vzduchem“ přes WiFi (over-the-air).

Kalibrace váhy\\
**a, b, c, d** - zvyšují kalibrační faktor o 10, 100, 1000 10000\\
**e, f, g, h** - snižují kalibrační faktor o 10, 100, 1000 10000\\
