High vs low arduino
WebApr 20, 2024 · These boards can switch on both the positive and/or the negative side and can be activated by the signal going high on the positive, or the signal going low on the negative, or in some applications both. If in doubt, check the ‘reference’ point of your output device and compare it to an ‘active pin’ to determine the polarity. WebMar 9, 2024 · Prior to Arduino 1.0.1, it was possible to configure the internal pull-ups in the following manner: 1 pinMode(pin, INPUT); // set pin to input. 2 digitalWrite(pin, HIGH); // turn on pullup resistors. NOTE: Digital pin 13 is harder to use as a digital input than the other digital pins because it has an LED and resistor attached to it that's ...
