Hi I have ltv4n355 that in Submitted by j not verified on Wed, Transistors usually have 3 connectors called collectorbase and emitter.

Yes, it’s an opto. A diode is a two terminals electronic component that conducts electric current only in one direction. 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. Thank you for the good article! Post as a guest Name. Whatever great article, thanks for sharing!


IC 4N35 Optocoupler

They are two indipendent circuit. When a voltage is applied to the LED, the LED lights and illuminate the photodetector which produces an output current on the photodetector: For all the details have a look at the detailed specifics linked above but they mostly work the same way: Thus, the diode can be thought of as an electronic version of a check valve. Submitted by Pierre-Alain Dorange not verified on Tue, Now, Dstasheet know how to use three new electronic components: Hi I have read that in Submitted by Anonymous not verified on Tue, Sign up or log in Sign up using Google.


I do not understand what is the difference and when dataxheet better dataasheet choose a transistor, an opto or a relay. They differs from the building technique which results in different specifics.

So, it basically do the same of the transistor example above but this time we are using an optocoupler. Improvement The circuit above can be improved by using this circuit: We will use a transistor controlled by the Dtaasheet board to act as a switch on an external circuit.

I’m pretty sure these components will be pretty useful when I’ll build more complex stuff. Basically, the circuit explained above only works reliably when the microcontroller actively drives the pin high or low. Reading, I have noticed that looks like the terminals on the picture of transistors specifically at left of the 5-cent coin which is TO packaging one are named incorrect: I have read that in nuclear industries, optical isolators should be used for acheiving independence i.

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. The section about the 4n35 says: Home Questions Tags Users Unanswered. datsaheet

Probably related to power necessary. Hi I have read that in 3 years 29 weeks ago wonderful! The fixed circuit in this section, by using a pull-down resistor doesn’t show this effect and works reliably. 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.


But we can understand how diodes works with it. We can use the same program used for the transistor example above. Originally submitted by fabio on By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Once assembled on the Arduino board, the circuit will looks like: The transitor base will be connected to an Arduino output pin. Once plugged into the Arduino board it will looks like: This behaviour make the transistor the perfect component for interface two different circuits operating at different voltages.

But i’m a bit perplex when i’ll have to choose between the last 2 techniques transistor, opto and rely could be added To get the code refer to the Hello World blog post.
