Master Arduino Digital I O: Inputs, Outputs, And Pwm
For example, in a 5V TTL system, a voltage between 2.0V and 5.0V may be thought-about HIGH, while a voltage between zero.0V and 0.8V might be considered LOW. Anything in between these ranges is usually undefined and might lead to unpredictable behavior. It’s crucial to consult the datasheet of the…
