But i don t understand how he is calculating to downgrade a b50k potentiometer for a 10k potentiometer.
10k potentiometer circuit diagram.
Potentiometer pin diagram click the image to enlarge it potentiometer pin configuration.
The only potentiometer we have on hand is a 10 kω unit.
U1 and u2 function as anti keybounce a logic jump from 000 to 111 or vice versa is not possible because once the maximum or minimum count is reached the co pin pin 7 of ic2 blocks further pulse entry.
I understand there are resistors of 24k and 4 7k in series s for the middle pin and 1 5k and 2 7k for the led.
The circuit diagram is given below.
Potentiometer working circuit diagram construction types resistor a small bundle of resistance is one of the most used basic components in an electric circuit.
The upper part of the slider is taken as r1 and the lower part of the slider is taken as r2.
In the above circuit diagram you can see there is only one resistor in the potentiometer but the slider divided the resistor into two.
This end is connected to one end of the resistive track.
Of course we could simply connect the potentiometer as is and have an adjustable range of 0 ω to 10 000 ω but that would be too coarse of an adjustment for our application.
Electronic potentiometer circuit diagram the position of s1 determines whether the resistance increases or decreases every time s2 is pressed.
This end is connected to the wiper to provide variable voltage.
