Hi I have read that in 3 years 29 weeks ago wonderful! A similar result could have been achieved using the MOS Irf transistor.

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. Whatever great article, thanks for sharing!

I suppose in this case, an optical isolator would prevent surges and other damaging events from passing to the parts that work well, while a resistor would let it pass right on through.

Post as a guest Name. We can use the same program used for the transistor example above.


We already know these terms from the transistor introduction above. You can download the video from http: What does this circuit do? The fixed circuit in this section, by using a pull-down resistor doesn’t show this effect and works reliably.

Search Search this site: I bought an Arduino starter kit with some basic components, and I know among them is an optocoupler. This is good when you don’t want dattasheet component further along in the system to affect previous components. Basically, the circuit explained above only works reliably when the microcontroller actively drives the pin high or low. Only the transistor let them interact. Well, the title says it all.

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. A simple Arduino based circuit using a diode We can build this simple circuit to show how diodes works: Yes, it’s an opto.

Last updated on Sun, I do not understand what is the difference and when it’s better to ltv4n53 a transistor, an opto or a relay. One of the pages in the datasheet will show the pinout: 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 Submitted by Pierre-Alain Dorange dstasheet verified on Tue, Looking forward to it! As datasheeet can see each time the output on pin 2 is HIGH our transistor will get a voltage on its base connector resulting in the collector and the emittor getting connected.


You can see a demo in the video below. Email Required, but never shown.

IC 4N35 Optocoupler

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. The circuit above once created using the Arduino board will looks like: Hi I have read that in Submitted by Anonymous not verified on Tue, They do exactly the same of ltf4n35 legs of a transistor.

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. Now, I know how to use three new electronic components:
