Hello,
I patched up the circuit as shown, however when it's ON, with the oscillator probe at point A, I could see only DC voltage (straight line), I was expecting some on/off action displayed on the screen. because PNP was used .
Any suggestion I could capture the waveform at point A?
Im using a 20MHz oscillator scope.
Datasheet of BC327 is attached.
The LEDs were 1W, forward voltage 3.2V~3.6V
Thanks
oookey
