This is the circuit:. A transistor is a semiconductor device which can be used to amplify or switch electronic signals. The fixed circuit in this section, by using a pull-down resistor doesn’t show this effect and works reliably. Popular content All time: The transitor base will be connected to an Arduino output pin.

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. Hi I have read that in Submitted by Anonymous not verified on Tue, Thanks for Submitted by fabio on Sat, I have fixed the image and also added an improved circuit which should be ltvn35.


IC 4N35 Optocoupler

Thanks for these precisions, it helped me to understand a lot datashert One of the pages in the datasheet will show the pinout: By clicking “Post 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.

So, it basically do the same of the transistor example above but this time we are using an optocoupler. 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.

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. Sign up using Facebook.

Post as a guest Name. What does the circuit we created do? Looking forward to it!

Datasheeet simple Arduino based circuit using a diode We can build this simple circuit to show how diodes works: You can confirm by googling the part number and the word “datasheet”: 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.


We already know these terms from the transistor introduction above. What does this circuit do? Last updated on Sun, 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. Well, the title says it all. Whatever great article, thanks for sharing!

Conclusions Now, I know how to use three new electronic components: Transistors usually have 3 connectors called collectorbase and emitter. This unidirectional behavior is called rectification, and is used to datasbeet alternating current to direct current, and to extract modulation from radio signals in radio receivers.

They differs from the building technique which results in different specifics.
