Take a look once more on figure 5. Ok, looking the figure 4, at 15mA there is about 1.

The output to the Arduino input port will be at the point named Channel II. Yes, my password is: From the datasheet I think a LED current in range mA should be enough to turn the transistor into saturation. Use anything from 1Kohm to to 10K. There datqsheet a simple formula to calculate the two resistor for each optocoupler?


So stick with figure 2 in the datasheet.

Jan 22, 6. If the opto is connected to some 5 volt logic gate or controller. It is much the same The input is a LED and the darasheet is a transistor.

Assume using figure 2 in the datasheet. Jan 22, ccny74-2. Hello people, i’m new to electronic circuits. No need to have the transistor conducting max current.

Jan 16, 7 0. Optocoupler fails after month. You will have values well inside the spec of the opto.

This will show the voltage drop versus current. If you feel for it use two resistors in series to get close to the value.

CNY74-4 Optocoupler

Do you already have an account? And you will no problem at all.

You have got how to calculate the LED series resistor correct. Go for a LED current equal to 15mA. Jan 22, Keep your kids engaged and get them excited about electrical engineering with these fantastic sites. Your name or email address: You May Also Like: I used this datasheet http: I guess a 4.

The second part of circuits work on 5VDC, because there are some TTL components like shift registers, cny74-22 etc. Jan 22, 8. OptoCoupler Posted by mpuvdd in forum: You do not need a value that is ohm. I would not have used a trimmer. Replace the nA with the current determined by the transistor Vce which you set correct to 0.
