Opto isolators arduino motor - Opto-isolator - Wikipedia
Introduction to Optocouplers (aka optoisolators), especially their use with microcontrollers Arduino, Raspberry Pi, etc.
Optocoupler Circuits. a photoFET, an optotriac, so that Q1Q2 and the motor turn on only when the computer output goes low.
These devices are called full logic optoisolators: their LEDs and sensors are fully encapsulated within a digital logic circuit. or pulsewidth motor control.
