| ASCII table | |
| Prints out byte values in all possible formats: | |
| - as raw binary values | |
| - as ASCII-encoded decimal, hex, octal, and binary values | |

| // for example, '!' is the same as 33, so you could also use this: | |
| // int thisByte = '!'; | |
| void loop() { | |
| // prints value unaltered, i.e. the raw binary version of the byte. | |
| // The Serial Monitor interprets all bytes as ASCII, so 33, the first number, | |
| // will show up as '!' | |

| Serial.print(", dec: "); | |
| // prints value as string as an ASCII-encoded decimal (base 10). | |
| // Decimal is the default format for Serial.print() and Serial.println(), | |
| // so no modifier is needed: | |
| Serial.print(thisByte); | |
| // But you can declare the modifier for decimal if you want to. | |
| // this also works if you uncomment it: | |
| // Serial.print(thisByte, DEC); | |
| Serial.print(", hex: "); | |
| // prints value as string in hexadecimal (base 16): | |
| Serial.print(thisByte, HEX); | |
| Serial.print(", oct: "); | |
| // prints value as string in octal (base 8); | |
| Serial.print(thisByte, OCT); | |
| Serial.print(", bin: "); | |
| // prints value as string in binary (base 2) also prints ending line break: | |
| Serial.println(thisByte, BIN); | |
| // if printed last visible character '~' or 126, stop: | |
| if (thisByte == 126) { // you could also use if (thisByte == '~') { | |
| // This loop loops forever and does nothing | |
| while (true) { | |
| continue; | |
| } | |
| } | |
| // go on to the next character | |
