Opto Isolator 12V To 5V at Thomas Mahomet blog

Opto Isolator 12V To 5V. I'm planning on using the switched 12v (potentially 11v to 14.4v) car system as inputs into the arduino. I'm trying to input 12v into ardunio digital inputs. The arduino will be running on 5v, provided by a. A typical example is a digital 24v signal of an industrial sensor that has to be read by an esp32 microcontroller. The protection is for both input and output. This simple circuit provides better than 1% accuracy in optically coupling a dc voltage signal. But since arduino digital input max voltage is 5v, i would like to use an optocoupler. The device has an internal protection form of electrical isolation. If it is open circuit, then the output terminal is simply connected. It can protect up to high.
