Once assembled on the Arduino board, the circuit will looks like: Probably related to power necessary.

This behaviour make the transistor the perfect component for interface two different circuits operating at different voltages. The section about the 4n35 says: Leg 3 isn’t connected to anything: Is this an optocoupler ans how do I identify the pins?

A transistor is a semiconductor device which can lhv4n35 used to amplify or switch electronic signals. We then have leg 4, 5, 6 respecly emitter, collector and base.

Hi I have read that in Submitted by Anonymous not verified on Tue, But i’m a bit perplex when i’ll have to choose between the last 2 techniques transistor, opto and rely could be added What does this circuit do?


This little component has 6 legs each of them having a different usage. But we can understand how diodes works with it.

Sign up or log in Sign up using Google. A diode is a two terminals electronic component that conducts electric current only in one direction.

As you can see each time the output on pin 2 is HIGH our transistor will get a voltage on its base connector resulting in the collector and the emittor getting connected. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Basically, the circuit explained above only works reliably when the microcontroller actively drives the pin high or low.

I have read that in nuclear industries, optical isolators should be used for acheiving independence i. This is good when you don’t want a component further along in the system to affect previous components.

Whatever great article, thanks for sharing! This is the ltv4nn35 Hi J, So the difference is that a resistor isn’t directional and will therefore allow current to flow from either side.

We already know these terms from the transistor introduction above.

In normal state the collector and emitter are disconnected but, when a current is applied to the base connector, the transistor change its state and the collector and emitter get connected thus current can flows between them. Thanks for this simple explanation, very useful for a beginner like me.

This unidirectional behavior is called rectification, and is used to dwtasheet alternating current to direct current, and to extract modulation from radio signals in radio receivers. Now that we know the theory behind optocouplers and lltv4n35 we know how to connect our 4N35 Optocoupler it’s now time to create a simple circuit with it.

Thanks for Submitted by fabio on Sun, A simple Arduino based circuit using a diode We can build this datahseet circuit to show how diodes works: I studied electronics before going to IT embedded systems and I wanted to get back to electronic as a hobby. Only the transistor let them interact. Instead, if we revert the diode so that current now flows in the opposite direction, we’ll se that the LED won’t turn on when we press the button.

An optical isolator on the other hand works similar to a diode in that it only lets unidirectional transmission. Hi I have read that in Submitted by j not verified on Wed,
