capacitance - Flashing LED circuits


How does the current flow through this circuit and thus how do the components work together to cause the flashing LED?


I know the basics in that the current first charges the capacitor which consequently turns on the transistors, however I don't understand the role of the resistors or how the circuit works as a whole. Also, why does the current first reach the 2.2uF capacitor first?


Thank you


the circuit

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
