See post#7.
its too confusing can you literaly just tell me
Do you have a 2N2222 transistor ?
Do you have any transistors ?
If so, what is written on it/them ?
Do you have a solderless breadboard ?
Do you have a soldering iron ?
No
Yes
Yes
Yes
I have a pn222 transistor.
Yes and the first line says: 2N The second one says: 2222A the last one says: -1726
Just to confirm, ?
2N
2222A
yes
Are we now going to have one post and reply for each individual component? Or several posts?
What resistors are being used? Also, do I need code?
void setup()
{
}
void loop()
{
for (unsigned int x = 200; x <= 4000; x += 100)
{
tone(8, x);
delay(200);
}
for (unsigned int x = 4000; x >= 200; x -= 100)
{
tone(8, x);
delay(200);
}
} //END of loop()

Why "tone", and why the transistor.
Didn't anyone read reply#12.
Leo..
too bad
Has @anon57585045 reserved #100 yet?
Gotta keep up with it. 
No. I will be #100.
