variable capacitor 22 (Footprint/Package: variable capacitor 1)
... hence the brightness of the lamp can be controlled by varying the POT R3. Capacitor C2 by-passes the lower half of the POT R3 when timing capacitor C1 is charged. The base frequency will be constant irrespective of the position of R3 and the duty cycle only changes. Capacitor C2 is meant for noise ...
