EL4N35 Optocoupler ***LOCAL STOCK***

Optocouplers enable you to control one circuit from another circuit with no electronic connection between the two circuits, for example to control a toy or device (switching it ON or OFF) from the Wiring hardware without tampering with the toys circuit. Just interrupt the line you want to control and attach both ends to the S1 and S2 signals. Internally the Optocupler has an LED. W\when the Wiring board sets the pin 8 to HIGH the internal LED turns ON activating an internal light sensor that enables the flow of electricity between whatever is connected to S1 and S2. There are different types of optocouplers but the functioning is very similar the 4N35 is just one type and it is useful for hacking toys running on batteries or small power adapters etc.
