TUTORIAL ON ARDUINO WATCHDOG TIMER A watchdog timer (WDT) is a hardware timer that automatically generates a system reset if the main program neglects to periodically service (reset) it. The Watchdog Timer is clocked from a separate On-chip Oscillator which runs at 1 MHz. This is the typical value at V CC = 5V. It is often used to automatically reset an Arduino that hangs ARDUINO LIGHT INTENSITY MEAUREMENT Definition The lux (symbol: lx) is the SI unit of luminance, measuring luminous flux per unit area.It is equal to one lumen per square meter. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through asurface.

ONE THOUGHT ON “ZERO TO HERO : ESP8266”*
ANDREA POLIZZI says: May 4, 2017 at 8:03 am I recommend it to those who are in the beginning (experts also), like me, and are looking for a text that easily explains the use of the esp8266 module. It is true that some information may be found on the internet, but, in my opinion, having everything at your fingertips in a single text can be an advantage, as well as not excessive cost.
