Alternate Led Flasher

Given Below is the circuit of "Alternate Led Flasher".

Here are the components you require to make this Electronic Kit:

Parts List:

• one IC 555 timer
• one 27k resistor
• one 220k resistor
• two 150E/1.5k resistors
• one non-electrolytic 0.01 Micro farad/ 10 nano farad capacitor
• one electrolytic 1 Micro farad capacitor and
  
• two LEDs (Preferably one red colour and one green colour) and ofcourse 6V batteries.

What does this circuit do?

Once you wire up the connection properly and connect it to a 6V battery source, the Two LEDs start flashing alternately. i.e. If one led is on, the other one is off. So we get the feeeling that the bulbs are flashing alternately.
