Shooting Game

Given Below is the circuit of "Shooting Game".

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

Parts List:

• one IC 555 timer
• one 27k resistor
• two 150 ohm resistors
• one 220k resistor
• one non-electrolytic 0.01 Micro farad/ 10 nano farad capacitor
• one electrolytic 1 Micro farad capacitor
• two Light Emitting Diodes (LED), preferably one red and one green
• one switch (spring back type) and ofcourse 6V power source.

What does this circuit do?

Here is an interesting game to test your sense of timing. After rigging up the circuit and connecting the battery press the switch. The LEDs start flashing alternately. Take any LED, say green. The switch should be released at the instant when the green LED lights up. If your timing is perfect, the green LED stays lit up (stops flashing) after the switch has been released, otherwise the red LED lights up indicating that you missed the 'shot' i.e. your timing was a bit late.
