int intValue = atoi(charValue);: Here, we use theatoi()function to convert the character arraycharValueto an integerintValue. Serial.println(intValue);: This line prints the converted integer value to the serial monitor. Output: 1234
Converting Byte to Integer Using theint()Function The most common method to convert a byte to an integer in Arduino is by using theint()function. This function takes a byte value as an argument and returns its integer equivalent. Here’s a simple example to illustrate this process: ...
int led=13;voidsetup(){// initialize the digital pin as an output.pinMode(led,OUTPUT);digitalWrite(led,LOW);Serial.begin(115200);Serial.println("please select 'o' or 'f' to control led:");}voidloop(){digitalWrite(led,HIGH);// turn the LED on (HIGH is the voltage level)delay(1000...
