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 BASED UNDERGROUND CABLE FAULT DETECTION The circuit is consists of 4 line display, arduino and resistance measurement circuit. Main component of the underground cable fault detection circuit is low value resistance measurement. It is constructed using a constant current source of 100mAmps. It can measure very low value resistance as the cables have around 0.01 Ohm/meter resistance. CONNECTING ESP32 TO WIFI NETWORK Connecting ESP32 to WiFi is first step when using ESP32. In all projects of ESP32 Connecting to WiFi and then accessing other thing is must. ESP32 can operate in three different modes: Wi-Fi station, Wi-Fi access point, and both at the same time. HOW TO CONVERT INTEGER TO STRING AND STRING TO INT ON In this tutorial we will see both integer to string and string to integer conversion. Conversion of integer to string can be done using single line statement. Example 1: Integer to String Conversion Arduino. int a = 1234; String myStr; myStr = String (a); //Converts integer to string. Example 2: String to Integer conversion Arduino. ARDUINO CONVERT STRING TO CHARACTER ARRAY Basically String type variable in arduino is character array, Conversion of string to character array can be done using simple toCharArray () function. Getting string value in character array is useful when you want to break single string into parts or get part of string. Generally, strings are terminated with a null character (ASCIIcode 0).

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. Good Book each aspect of ESP8266 covered very well. Comments are closed.OUR E-BOOKS
