Hello, I'm a computer science student and I was assigned by my professor to make a monostable multivibrator circuit on a bread board with an unstable duration of three seconds. Keep in mind I have very little knowledge about circuitry, we were only given the schematic and were told to find the...
Hello all,
I have read some articles on how to test a transistor with DMM diode mode and what I understand is that measuring from Base (red probe) to Collector\Emitter (black probe) should give a reading and all other probings (C-to-E, E-to-C, C-to-B, E-to-B) should give O.L.
But that isn't...
Hi there!
I am currently looking for 2SA1708 and 2SC4488 transistor models to integrate into Spice, but I could not find any model on the web. Could you please help me if you have the related models? Or can you please give me feedback about what parameters are the most important ones to model...
Hello everyone, I would really appreciate if you could help me
Im making a mini fridge controller (PID), using a 4n25 optocoupler, an IRFZ44n Mosfet and a tec peltier
I connect it to a 12v and 3 A and arduino 5v
As soon as the arduino code is uploaded and I connect it, the mosfet starts to...
Hi Im using a NPN Transistor output Optocoupler (Toshiba TLP290) as a level shifter.
I have a source squarewave and a constant current chip (20mA) in series to drive the Optocouplers internal LED.
The idea is that the constant current chip will allow the optocoupler to be safely and...
We kinda learned about this circuit in the electronics 1 lab, but I don't understand everything, i have some questions and unfortunatly my lab professor is quite a Karen and won't even hear my questions... Anyway, these are my questions:
1) Which elements can I mess with to increase the volume...
