![]() In this article you saw how to read and write objects (float types, integers, text and more) easily! Please feel free to post your questions and feedback. I hope you will be able to use these functions in your next project and easily store and retrieve custom datatypes easily. EEPROM.put (eeAddress, f) The EEPROM.put is the key here. One simple call, with the address first and the object second. int eeAddress 0 //Location we want the data to be put. float f 123.456f //Variable to store in EEPROM. Serial.write() accepts byte and bytearrays, but what's the best way to convert the values to bytes I tried to cast an int16 to an byte, without luck. ![]() Serial.println( "Read custom object from EEPROM: " ) Writing a FLOAT data type into Arduino UNO. What's the best way to send float, double, and int16 over serial on Arduino The Serial.print() only sends values as ASCII encoded. EEPROM.get( eeAddress, customVar ) EEPROM.get( eeAddress, customVar ) Once you read it, you can print the object elements easily. While reading the data, you have to make sure you send the object parameter correctly. The function interface is too simple and very helpful. The EEPROM put() function accepts simply the address and the object. The address in the EEPROM where you want to write the data.Int eeAddress = 0 //Location we want the data to be put. Writing a FLOAT data type into Arduino UNOįloat f = 123.456f //Variable to store in EEPROM. ![]() You can use this link to play with the simulator, tinker with the code and add useful sections to your projects in the future!įeel free to share your feedback on this article in the comments Serial monitor window on Wokwi Arduino Simulator ![]()
