| ASCII table |

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

| // you can also write ASCII characters in single quotes. |
| // 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.write(thisByte); |
| |
| 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 |
