Connect pin 2 of the 4N35 to pin 7 of the control board, and pin 1 to a 1K current limiting resistor and then to 5V. Connect pin 4 to GND of the Uno, and pin 5 to the cathode of the LED. Then hook the anode of the LED to 5V after connecting with a 220 Ohm resistor.

(S117478447) Web6 mrt. 2024 · It is very important to be able to distinguish when you have a PNP sensor, or when your digital controller requires a PNP sensor input. In order to identify the sensor, we can use the datasheet, or often the diagram on the side, and even a voltmeter. The datasheets will always list the polarity of a device that is PNP (or its partner, NPN). sharon sahertian
