Well, the title says it all. Once assembled on the Arduino board, the circuit will looks like: What does the circuit we created do?

Looking forward to it! This confirms the behaviour of a diode: This is the circuit:.

Once plugged into the Arduino board it will looks like: When a voltage is applied to the LED, the LED lights and illuminate the photodetector which produces an output current on the photodetector: Post as a guest Name. 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.

Only the transistor let them interact. Thanks for Submitted by fabio on Sun, Search Search this site: Probably related to power necessary.

satasheet If we plug the diode as seen on the pictures above when we’ll push the button the LED will turn on. The transitor base will be connected to an Arduino output pin. Note that the circuit coming from Vin 9V is actually completely separated from the one coming from the Arduino board. You can see a demo in the video below.

The other circuit could be the one operating a DC motor which needs a lot of dattasheet and current. The section about the 4n35 says: The simple circuits I built will be used as base for more complex stuff.


A simple Arduino based circuit using transistors We will use a transistor controlled by the Arduino board to act as datasheeet switch on an external circuit. A similar result could have been achieved using the MOS Irf transistor.

This is good when you don’t datashwet a component further along in the system to affect previous components. This is preferable against the one explained before because it won’t float when the microcontroller is shut off or when it is not actively drive the pins. Thanks for this simple explanation, very useful for a beginner like me. I studied electronics before going to IT embedded systems and I wanted to get back to electronic as a hobby.

Dxtasheet can confirm by googling the part number and the word “datasheet”: Sign up using Email and Password. The circuit above once created using the Arduino board will looks like: Basically, the circuit explained above only works reliably when the microcontroller actively drives the pin high or low.

Now, I know how to use three new electronic components: I have fixed the image and also added an improved circuit which should be better. Originally ltv43n5 by fabio on This unidirectional behavior is called rectification, and is used to convert alternating current to direct current, and to extract modulation from radio signals in radio receivers.

Transistors usually have 3 connectors called collectorbase and emitter. But i’m a bit perplex when i’ll have to choose between the last 2 techniques transistor, opto and rely could be added You can download the video from http: Hi I have read that in nuclear industries, optical isolators should be used for acheiving independence i.


The BC is not capable of delivering lot of current so use it with care. I’m pretty sure these components will be pretty useful when I’ll build more complex stuff. Could you datashee explain to me why?

Hi J, So the difference is that a resistor isn’t directional and will therefore allow current to flow from either side. So, it basically do the same of the transistor example adtasheet but this time we are using an optocoupler. 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.
