Serial.print and printf, Solved! in Arduino IDE and ESP. You’d like to be able to print values from inside strings, similar to printf. Since the Arduino IDE understands serial.print, you won’t be able to type anything for Arduino Uno, Arduino Mega or Arduino Nano etc like the statement below: Serial.printf(“You Entered %d hours”, n); However, … Read more
Here’s how to use the CMD prompt to upload a .hex file (compiled hex file) to Arduino without using the Arduino IDE. Also, how to use the command prompt to upload a .bin file to an ESP8266 or ESP32. If you’re not sure what .hex and .bin files are, read on. The code written in … Read more
This article will explain what an EEPROM is and provide a brief overview of the other memories available in a microcontroller. You”ll also learn how to use EEPROM in Arduino and ESP microcontrollers (ESP8266 and ESP32). Using the EEPROM put and EEPROM get functions, the software below illustrates how to read and write to EEPROM. … Read more
