This code first syncs the DS1302 chip with a NTP server and then reads time from the DS1302 chip. Every time the system is booted the clock is synced with a NTP server. #include <ESP8266WiFi.h> #include “TinyDHT.h” // Adafruit library https://github.com/adafruit/TinyDHT #include <ThreeWire.h> // needed by rtc #include <RtcDS1302.h> // Makuna library https://github.com/Makuna/Rtc const char… Continue reading Sync Ds1302 with NTP

Arduino as an Oscilloscope
Yes an Arduino can be used as Oscilloscope without any additional hardware. Burn this code to Arduino const int probePin = A0; void setup() { //Setup serial connection Serial.begin(9600); } void loop() { //Read analog pin int val = analogRead(probePin); //Write analog value to serial port: Serial.write( 0xff ); //can be skipped… Continue reading Arduino as an Oscilloscope
Burning Arduino Bootloader to Atmega8 or other Atmega
This is for all who are having problems in burning the Arduino Bootloader on an Atmega8 or any other Atmega Processor using a Arduino Board like Arduino Uno. The processor for the first time burning will have to be used with an external oscillator. I was trying without the external oscillator (was depending on the… Continue reading Burning Arduino Bootloader to Atmega8 or other Atmega
