With this code the micro controller is acting as if it's a pull-up resistor and not pulldown. The RGB-led seems also to not handle this code without adding a minimum of delay (1); ...

It's important to have a grasp of how to read Arduino resistors, as they're useful for controlling the current in an electrical circuit.

In order to accomplish this, [Bas] is using a light-dependent resistor and a pull-up resistor to create a resistance bridge, which is then connected to an analog input pin on a Raspberry Pi Pico.

Is it (would it be) possible to use (enable/disable) the internal (weak) pullup-resistor trough a LINX function from Labview on a digital Arduino pin? Probably you know, but arduino's have a build in, ...

Yes, in less than 1/4 of one second an Arduino can open any of the millions of these locks in service. The exploit in Onity programmable keycard locks was revealed by [Cody Brocious] at the ...
