WebAug 11, 2015 · When you look at the source code of Arduino, HIGH is defined as 1 and LOW is defined as 0 using #define. You may heard about Preprocessor, Compiler, and Linker. … WebIf the pin isn't connected to anything, digitalRead() can return either HIGH or LOW (and this can change randomly). The analog input pins can be used as digital pins, referred to as A0, A1, etc. The exception is the Arduino Nano, Pro Mini, and Mini's A6 and A7 pins, which can only be used as analog inputs. .

WebMay 5, 2024 · It will work, only because both HIGH and true are defined as 1, while LOW and false are both defined as 0. Also, digitalWrite looks for a zero, or non-zero value, not just 0/LOW or 1/HIGH. It would, arguably, be better style-wise to do either: if (light) digitalWrite (LED, HIGH); else digitalWrite (LED, LOW); or, equivalently WebHIGH is just an alias for the number 1. LOW is just an alias for the number 0. Anywhere you can use numbers you can use HIGH or LOW equally. You can even use them in math: HIGH + HIGH == 2. The same goes for things like INPUT, OUTPUT, RISING, FALLING, etc. They are just aliases to numbers. –
