Some Basics in simple electronic.


This adj. resistor lead to ground.
A poti have even tree contacts.

In some circuits it's very important ,if the middle contact is not
soldered to one of the outer one,, so there's a infinity load to the circuit if the middle contact left from his path.
For example some dust on the way.

Some circuits die.

But not in this circuit

from where i can get square wave out put as



10a & 12a closed ... 10c & 14c opened ----> square wave

10a & 12a closed ... 10c & 14c closed ----> sawtooth

Close the bridge like written in the text. Or solder just one way.

555 is also possible like MAX2206cp or MAX2008cp or
or CD4060 and hundret other ,but it's easyer to take my cicuit. So 741 op's
are one of the most used IC's over the world.

This evening im uploading a very detailed noise generator circuit.

hi
i just make this 555 timer circuit . MAX voltage is 18V and in output coming 15V... is there any idea to get it 17 to 23

i can,t wait to see noise circiut........

i am uploading this 555 timer cricuit output is great square wave but 15V
