diodes Can I use a BC547 NPN transistor as a

2020 4 12 · In the article Electronic Thermometers for Brewers Ken Schwartz talks about how to use a 2N4401 to create a diode thermometer:. I attempted a similar setup with a BC547 transistor ( BC547 Transistor NPN 45V 0.1A ) but I'm not having any luck with it. According to the BC547 datasheet the emitter and collector are opposite from the drawing above, but I tried both ways and neither one

diodes Testing a Bipolar Junction Transistor using an

2020 5 3 · This video says I should see ohmmeter deflection with an NPN transistor, placing positive probe on the base, and negative probe on collector or emitter.. A BC547 NPN is giving me opposite results ohmmeter deflection with negative probe on the base, and positive probe on collector or emitter. I tested a simple rectifier diode with the same ohmmeter. I got meter deflection with positive probe

Simple Heat Sensor or Temperature Sensor Circuit

2  · For PNP transistor E will be positive terminal and B C will be negative. Hence by shorting the B and C, we can use transistor as Temperature Detector. Below is the NPN transistor BC547 Pin configurationOperating temperature of Transistor BC547 is up to 150 degree C, so it can be perfectly used at high temperature as a Heat Sensor.

How to Use Resistors with LED, Zener and Transistor

In this post we learn how to use resistors while designing an electronic circuits using LEDs, zener diodes, or transistors. This article can be very useful for the new hobbyists who normally get confused with the resistor values to be used for a specific component and for the desired application.

BjTerm. Arduino Thermometer With Analog Sensor

BjTerm. Arduino Thermometer With Analog Sensor and BargraphRecently I got Arduino starter kit as a gift. It caused me to have fun like a child with building blocks ;)In this Instructable, I'll show You one of the circuit that I built digital thermometer with simple analog sensor based on single BJT tran

1. Ok, start to play;) After some test of every elements i decided to build digital thermometer. Digital but analog, with very basic analog sens2. The forward voltage on is dependent on the temperature and the flowing current. The temperature coefficient also depends on the collector curren3. Every Arduino board has a multiple analog inputs. Transistor and diodes are very cheap so You can add more channels to our thermometer. I added4. In last step I made analog like display, namely a LED bargraph. In Arduino Examples >07.Display >barGraph is a piece of code which I modif

How to Activate Relay using Transistor? Physics Forums

2015 1 19 · I also don't want to use FET because I don't have any idea about it except it switches faster than BJT. Well, I don't want to mess in FET while I am having trouble to BJT. One more thing, I honestly don't get it"I can't get your circuit to work with even a pair of BC547s. I think it can be made to work by substituting a JFET for the BC547.

Audio Amplifier with Common Transistors · One

2020 5 20 · The design is straightforward. A common small signal NPN transistor (like BC547, 2N2222, 2N3904, S8050) drives a balanced power amplifier made of similar transistors. The output transistor pairs can be BC327 with BC337 or S8050 with S8550. They must handle peak currents of 300 400mA (this is why BC547/BC557 or 2N3904/2N3906 should not be used

Transistor ApproximationsNPN BC548 vs. 2N3904,

2009 4 6 · My problem is I couldn't find the two transistors, NPN BC548 and PNP BC559 at any of my nearby Radio Shacks. After comparing the spec sheets online and doing a little bit of googling, I found that PNP transistor 2N3906's characteristics and specs seem to fit pretty well with BC559 and BC548 fits fairly well with 2N3904's.

Simple Fire Alarm Circuit Using Thermistor,

2020 5 21 · This transistor can bear power quite larger than the BC547 and it is also equipped with a heat sink for that purpose. When the BC107 transistor turns on, it allows current to pass from power supply to ground through collector thereby acting as an electronically controlled switch.
