I am driving columns of eight PIN diodes, each in an array for a project. All of the columns are tied to a common ground. I expect the current of the parallel diodes to be approximately 90 mA (11 mA per diode x 8). See schematic below. I am using the Arduino Uno R3 as my digital controller. To my un…
