Question : length of an array arduino
Answered by : successful-sardine-3yjove3uqycz
This program prints out a text string one character at a time. Try changing the text phrase.
char myStr[] = "this is a test";
void setup() { Serial.begin(9600);
}
void loop() { for (byte i = 0; i < sizeof(myStr) - 1; i++) { Serial.print(i, DEC); Serial.print(" = "); Serial.write(myStr[i]); Serial.println(); } delay(5000); // slow down the program
