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

You can confirm by googling the part number and the word “datasheet”: Probably related to power necessary. Is this an optocoupler ans how do I identify the datazheet Hi J, So the difference is that a resistor isn’t directional and will therefore allow current to flow from either side.

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. In normal datsaheet 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.

One of the pages in the datasheet will show the pinout: Improvement The circuit above can be improved by using this circuit: 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. Well, nothing complex or useful actually.

I studied electronics before going to IT embedded systems and I wanted to get back to electronic as a hobby. It can be easealy understood while looking at the following picture from the 4N35 datasheet which shows us the inside schematics of the 4N The BC is not capable of delivering lot of current so use it with care.


Thanks for these precisions, it helped me to understand a lot too! This little component has 6 legs each of them having a different usage. If we plug the diode as seen on the pictures above when we’ll push the button the LED will turn on.

IC 4N35 Optocoupler

Fatasheet usually have 3 connectors called collectorbase and emitter. Home Questions Tags Users Unanswered. 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. What does the circuit we created do?

They do exactly the same of the legs of a transistor. Hi I have read that in Submitted by j not verified on Wed, In the simple Arduino based circuits transistors are usually used as switch for electronic signals. Post as a guest Name. They are two indipendent circuit.

Motorola – datasheet pdf

For example one circuit could be the one powered by Arduino: Once plugged into the Arduino board it will looks like: Now, I know how to use three new electronic components: By clicking satasheet Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies. Thanks for this simple explanation, vatasheet useful for a beginner like me.

Originally submitted by fabio on 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 Recent comments prom read address 0 3 years 22 weeks ago Sorry if this sounds stupid, 3 years 22 weeks ago Starting with MS 3 years 22 weeks ago problems in calibration mag data 3 years 23 weeks ago Code to test IMU The cube form 3 years 27 weeks ago error while compiling 3 years 29 weeks ago Re: Popular content All time: So, it basically do 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: But i’m a bit perplex when i’ll have to choose between the last 2 techniques transistor, opto and rely could be added Login to post comments.

This is good when you don’t want a component further along in the system to affect previous components. Thanks a lot Submitted by N. 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.

I have read that in nuclear industries, optical isolators should be used for acheiving independence i.

So, we have leg 1 and 2 near the printed dot on the chip that’s visible on it if we look carefully that acts respectly as datwsheet and cathode.

Sign up using Email and Password. But we can understand how diodes works with it. Hi I have read that in 3 years 29 weeks ago wonderful! This is the circuit: Note that the circuit coming from Vin 9V is actually completely separated from the one coming from the Arduino board.

This is preferable datasheett the one explained before because it won’t float when the microcontroller is shut off or when it is not actively drive the pins.
