KNIGHT RIDER LIGHTS

Guys while driving you had seen some lights on the road. They are blinking in a fixed pattern like they are also riding with you. These lights mostly placed at the middle or at the divider side of the road. These lights are called KNIGHT RIDER LIGHTS.

Concept :-
                   Concept of Knight Rider Lights are very similar to the concept of TRAFFIC LIGHT or ELECTRONIC DICE . Only combination of diodes are changed.

4017 counter and 555 timer :-

  

List of components :-

• 3.3k ohm resistance - 1
• 8.2k ohm resistance - 1
• 10k ohm resistance - 1
• 1k ohm resistance - 6
• 100k ohm resistance - 1
• 1N4148 diode - 8
• 10uf electrolytic capacitor - 1 
• 0.01uf ceremic capacitor - 1
• 6.8nf ceremic capacitor - 1
• LED (any color) - 6
• 555 timer IC - 1
• 4017B counter IC - 1
• 9V battery - 1

Circuit for Traffic Light :-

Note :-

                Do not give more than 9 volts.

Make the above circuit and arrange the LED,s in the form of traffic light and enjoy it.

TRAFFIC LIGHT

Here is one more minor project for you.
While driving you see traffic lights on the road. Now you can make your own traffic light. like below.....

Concept :-
                   
                      Concept of traffic light is very simple. Here is same concept as we discussed in ELECTRONIC DICE. Here 555 timer IC generates the delay among RED, YELLOW and GREEN light and with the help of 4017 counter IC and combinations of diodes we can see the output on RED, YELLOW  and GREEN LED's.

4017 counter and 555 timer :-

List of components :-

• 22k ohm resistance - 2
• 10k ohm resistance - 1
• 1k ohm resistance - 3
• 100k ohm resistance - 1
• 1N4148 diode - 6
• 47uf electrolytic capacitor - 1 
• 0.01uf ceremic capacitor - 1
• 6.8nf ceremic capacitor - 1
• LED (red, yellow, green) - (1,1,1)
• 555 timer IC - 1
• 4017B counter IC - 1
• 9V battery - 1

Circuit for Traffic Light :-

Note :-

                Do not give more than 9 volts.

Make the above circuit and arrange the LED,s in the form of traffic light and enjoy it.
