Transistor as as switch - replace BC547 with S8050 - General ...
2017年12月6日 · The S8050 is categorized as "a low voltage high current small signal NPN transistor, designed for Class B push-pull audio amplifier and general purpose applications." Mikeb1970 December 6, 2017, 5:47pm
Powering and controlling a 5v rgb strip with NPN s8050 instead of ...
2021年11月3日 · I was wondering if i could use something like these: S8050 Transistor Pinout, Features, Equivalent, Circuit & Datasheet (components101.com) I don't actually have any wiring yet, as i'm afraid of frying the arduino if i actually have to plug in an external power supply. Hope this clears it up a little bit and again, sorry.
Is a 2n3906 an suitable substitute for a S8050? What about …
2011年6月8日 · Well they look very similar but the S8050 has a slightly higher gain. That shouldn't matter much in a H-bridge especially as such low loads. Also the the S8050 gas a higher emitter base saturation voltage which is normally a bad thing but …
General base resistor transistor calculation - Arduino Forum
2021年11月19日 · I am sure this is a very basic question, but I just want to be sure to not make any mistakes. I am using a transistor S8050 D331 to switch leds. So the base is connected with 1K resistor to the Arduino Due (3,3V) outputs. The emitter is connected to ground. The collector is connected to 1 led and a series 220Ohm resistor. The collector voltage is a seperate 5V supply. Now the leds are too ...
[SOLVED] s8050 transistor vs BC547 transistor - Arduino Forum
2019年7月7日 · Hello all, I'm currently trying to build a simple motion detector with a small alarm buzzer, namely the HC-SR501 module. A project that im currently following along with states that he/she is using a BC547 transistor... but i dont have one of these. Is it feasible to use something else? I currently have a few PN2222 and S8050 transistors, and was wondering if I …
DC motor control using arduino and transistor
2015年4月8日 · Hi, I am trying to control the speed of a toy 130 DC motor using arduino and transistor. Using the following layout: I am using a S8050 transistor The S8050 has a different pin config than the one shown in the dummies website, so basically Ive reversed it. The pot. value is ok and the value fed to pin 9 is ok (as seen from the serial output). However, a lot of the voltage seems to have been ...
Problema saturazione transistor S8050 (NPN) - Arduino Forum
2019年9月17日 · Controlla se hai scambiato i terminali del transistor o del modulo laser. Per il transistor sono E-B-C come da figura in questo datasheet. Per il modulo laser vedi qui. Tieni la R1 a 1000 Ohm, vanno bene. Ciao, P.
Control motor with PWM use transistor? mosfet? - Arduino Forum
2016年5月20日 · Hello I'm trying to control a small dc motor through arduino using PWM. The dc motor will run off its own 3v 1A power supply. Originally I wanted to go with transistor s8050, but when I plugged the power supply and checked the current being drawn by the motor, it showed 1.1 Amps. So s8050 will not work (unless I'm wrong) because the collector can handle max of 700mA. At this point don't know ...
TIP120 transistor base current from arduino
2015年1月22日 · The only thing that works is if i have a smaler transistor that helps the TIP 120 to "close". Do i need 2 transistors to drive the solenoid? I have tested to use a flyback diode and without resistor and that doesnt work either when i only have the TIP120. The smal transistor is a s8050. This wiring works. photo host. This wiring doesnt work
NPN transistors and their math - Arduino Forum
2020年5月11日 · Hi there, I'm new to transistors and while doing an excercise on the Freenove UNO (similar to the Arduino UNO), I took some readings with my multimeter, in order to get a better understanding of what's going on. I would like to know if my logic is correct. The circuit diagram is attached, I'm using the active buzzer in the kit and the S8050 NPN transistor. So knowning that transistors will ...
