4N35, 4N36, 4N37 product information

The simple circuits I built will be used as base for more complex stuff. Thanks for this simple explanation, very useful for a beginner like me. Well, nothing complex or useful actually. We will use a transistor controlled by optocouler Arduino board to act as a switch on an external circuit.

Transistors usually have 3 connectors called collectorbase and emitter. It can be easealy understood while looking at the following picture from the 4N35 datasheet which shows us the inside schematics of the 4N You can see a demo in the video below.

Last updated on Sun, Conclusions Now, I know how to use three new electronic components: A transistor is a semiconductor device which can be used to amplify or switch electronic signals. You can download the video from http: Now that we know the theory behind optocouplers and that we know how to connect our 4N35 Optocoupler it’s now time to create a simple circuit with it. Note that the circuit coming from Vin 9V is actually completely separated from the one coming from the Arduino board.

To get the code dataxheet to the Hello World blog post. A similar result could have been achieved using the MOS Irf transistor.

This little component has 6 legs each of them datashheet a different usage. The most common function of a diode is to allow an electric current to pass in one direction called the diode’s forward direction while blocking current in the opposite direction the reverse direction.

For bigger currents eg powering motors the MOS Irf will be perfect.

They differs from the building technique which results in different specifics. A simple Arduino based circuit using a diode We can build this simple circuit to show how diodes works: Thanks for Submitted by fabio on Sat, Improvement The circuit above can be improved by using this circuit: Submitted by Pierre-Alain Dorange not verified on Tue, The fixed circuit in this section, by using a pull-down resistor doesn’t show this effect and works reliably.

What does this circuit do? This is the circuit:. Thank you for the good article! But we can understand how diodes works with it. So, it basically datashwet the same of the transistor example above but this time we are using an optocoupler.

The circuit above once created using the Arduino board will looks like: Now, I know how to use three new electronic components: Good article Submitted by AN not verified on Sun, An Arduino based circuit using an 4N35 Optocoupler Now that we know the theory behind optocouplers and that we know how to connect our 4N35 Optocoupler it’s now time to create a simple circuit with it.

IC 4N35 Optocoupler

Hi I have read that in 3 years 29 weeks ago wonderful! When a voltage is applied to the LED, the LED lights and illuminate the photodetector which produces an output current on the photodetector: I’m pretty sure these components will be pretty useful when I’ll build more complex stuff. Originally submitted by fabio on Confused Submitted by Hubschrauber not verified on Sun, We already know these terms from the transistor introduction above.

Only the transistor let them interact. I do not understand what is the difference and when it’s better to choose a transistor, an opto or a relay.

They do exactly the same of the legs of a transistor. So the difference is that a resistor isn’t directional and will therefore allow current to flow from either side.
