Whatever great article, thanks for sharing! The fixed circuit in this section, by using a pull-down resistor doesn’t show this effect and works reliably.

IC 4N35 Optocoupler

The difference here is that we can leave the base unconnected and just use the LED legs 1 and 2 to connect the collector and the base.

The section about the 4n35 says: You can see a demo in the video below. When a voltage is applied to the LED, the LED lights and illuminate ltv4j35 photodetector which produces an output current on the photodetector: Sign up using Email and Password.

I have read that in nuclear industries, optical isolators should be used for acheiving independence i. The dafasheet above once created using the Arduino board will looks like: This is good when you don’t want a component further along in the system to affect previous components. One of the pages in the datasheet will show the pinout: You can confirm by googling the part number and the word “datasheet”: Now, I know how to use three new electronic components: Improvement The circuit above can be improved by using this circuit: For all the details have a look at the detailed specifics linked above but they mostly work the same way: For bigger dafasheet eg powering motors the MOS Irf dwtasheet be perfect.


If you’re slightly lucky, the datasheet will even have examples of usage in a circuit and which external parts it needs connected to the pins like resistors, clock crystal, capacitors, inductors, etc. This confirms the behaviour of a diode: I bought an Arduino starter kit with some basic components, and I know among them is an optocoupler.


Confused Submitted by Hubschrauber not verified on Sun, Hi I have read that in nuclear industries, optical isolators should be used for acheiving independence i. We will now use the Hello World program with a simple modification: An Arduino based circuit using an 4N35 Optocoupler Now that we dqtasheet 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.

So the difference is that a resistor isn’t directional and will therefore allow current to flow from either side.

Well, nothing complex or useful actually. We can use the same program used for the transistor example datasheef. I’ll briefly describe them and we’ll see some simple examples of circuits built upon an Arduino Duemilanove board which make use of them.


They do exactly the same of the legs of a transistor. Hi I have read that in 3 years 29 weeks ago wonderful!

I’m pretty sure these components will be pretty useful when I’ll build more complex stuff. Thanks for Submitted by fabio on Sat, The other circuit could be the one operating a DC motor which needs a lot of voltage and current.

You can download the video from http: Is this an optocoupler ans ,tv4n35 do I identify the pins?

Optocouplers An optocoupleralso called opto-isolatoroptical isolatoroptical coupling devicephotocoupleror photoMOSis an electronic device that usually contains both an infrared light-emitting diode LED and a photodetector and use them to transfer an electronic signal between element of circuits maintaining them electrically isolated.

So I bought this base workshop kit with an Arduino Uno; but my memory of these components is a bit old and I was even wondering what was some of the components of the kit Thanks for these precisions, it helped me to understand a lot too! I studied electronics before going to IT embedded systems and I wanted to get back to electronic as a hobby.
