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.

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. As you can see each time the output on pin 2 is HIGH our transistor will get a voltage on ltb4n35 base connector resulting in the collector and the emittor getting connected.

A simple Arduino based circuit using transistors We will use a transistor controlled by the Arduino board to act as a switch on an external circuit. Thank you for the good article!

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. Post as a guest Name. A transistor is a semiconductor device which can be used to amplify or switch electronic signals. Thanks for Submitted by fabio on Sun, Reading, I have noticed tlv4n35 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: If we plug the diode as seen on the pictures above when we’ll push the button the LED will turn on.

A similar result could have been achieved using the MOS Irf transistor. The most common function of a diode is to allow an electric current to pass in one direction called the diode’s forward direction while blocking current in the opposite direction the reverse direction.

I studied electronics before going to IT embedded systems and I wanted to get back to electronic as a hobby. I bought an Arduino starter kit with some basic components, and I know among them is an optocoupler. I have read that in nuclear industries, optical isolators should be used for acheiving independence i. 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.

It can be easealy understood while looking at the following picture from the 4N35 datasheet which shows us the inside schematics of the 4N Improvement The circuit above can be improved by using this circuit: We will use a transistor controlled by the Arduino board to act as a switch on an external circuit.

Email Required, but never shown. We already know these terms from the transistor introduction above.

I saw schematics using both relay and transistor This is the result: In the simple Arduino based circuits transistors are usually used as switch for electronic signals. Probably related to power necessary.

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. Is this an optocoupler ans how do I identify the pins? The transitor base will be connected to an Arduino output pin.

For bigger currents eg powering motors the MOS Irf will be perfect. When a voltage is applied to the LED, the LED lights and illuminate the photodetector which produces an output current on the photodetector: Now, I know how to use three new electronic components: Hi I have read that in 3 years 29 weeks ago wonderful! But i’m a bit perplex when i’ll have to choose between the last 2 techniques transistor, opto and rely could be added Thanks for noticing and posting a comment.

Note that the circuit coming from Vin 9V is actually completely separated from the one coming from the Arduino board. You can download the video from http: This dataasheet component has 6 legs each of them having a different usage. The fixed circuit in this section, by using a pull-down resistor doesn’t show this effect and works reliably.
