I understood what you said, but some doubts,At start, all Q s off, Cs discharged. Power on; Cs start charging, say Q1 turns on first- red LED on,C2 slowly discharges thru R4., green LED off, C3 continues to charge turning on Q3 which then discharges C1 turning off Q1
allowing C2 to start charging turning Q2 & green LED on. Make any sense??
Why that path ?C1 charges through LED3, R3 and R6, slowly increasing current through Q1. The MOSFETs have an ohmic region where the LEDs will will come on and get brighter as it charges and dimmer as they discharge.
It's a good read, but not much help when the schematic is drawn poorly in the first place!Hello,
Here I found a page with information on how to read an electronic schematic:
That site also uses the newer convention.
