3 EASY TRANSISTOR PROJECTS

3 Easy Projects using Transistors and some components and Battery.

These are really easy projects that you can do for school project and can be constructed on breadboard and need NO Soldering!.

Circuit and details.

The list of projects made here are:

LED Blinker using 2 transistor
Automatic Night Light
Water Level Buzzer Indicator

[Creativity]

The 3rd one really deserved a thumbs up👍

[digitexstudios]

For that first circuit, I’m pretty sure you just invented the 555 timer. Nice!

[hh-tlso]

yr i am surprised ke bread boad pr bhi yeh ban sakta hai, warna usually ye circuit electric playground pr bante hena... really deserved a sub

[tandavakrishna]

good one bro but for students please put circuit diagram with symbols

[dorothycurtis]

Thank you for this video! I've made the last one and it works!!! Thanks again!!

[johnwriterpoet]

Thanks for helping me understand breadboard connections!

[naisarmarzoona]

Super! thanks for helping to create my circuits

[jonathan-wqhh]

Thx bro!!! I searched so long for that automatic light when it is dark!! Super video. Thumbs up

[someOne-lsrl]

Love your content bro
Keep on doing what you're doing

[chrisciantrinidad]

Why I cant make the 2nd circuit happen

[francesco]

I hope you are still answering questions but what purpose do the transistors serve? I know they are important but the same kind of happens without the transistors. So what information am I missing? Thank you so much btw

[ninovitaliano]

i never really understood transistors. thanks for this!

[manojprabhakar]

Bro for led blinker, everything alright okay but my 2 leds are getting light but not blinking

[dayxibanon]

Hi, for your project, are you using a 47 kohm resistor or a 4.7 kohm because your description isn't the same as your video

[annabuhlbechmann]

Which program do you use to sketch the schematics for the projects?

[harshal.karadkar]

Will u please explain that automatic night light.

[roshanaara]

3rd one experiment which wires we must use to keep in waterr

[efthymiostsoumetis]

For the first project can I use a PN2222 or a S8050 transistor?

[SaimunAhmed]

what kinds of wire you used in these projects, i have make circuit using your video for automatic night light, but light is not turning on, when i had put positive and negative wire of 9V battery dirrectly on the positive and negative side of LED, then the led just turn on for seconds, then again led can not turning on, what should i do now?

[VishnuVardhan-rusz]

2nd project is working only when I place my finger on it .it's not working when I remove my finger and in dark. What might be the problem?
