Step 1: TRAFFIC LIGHTS

Traffic lights are very important for roads as they control the flow of traffic.Making one of these is very easy and we r going to do it!!

Step 2: COLLECTING MATERIAL

Materials needed --:

a) Arduino Uno

b) Bredboard

c) 3 Red Led's

d) 3 Yellow Led's

e) 3 Green Led's

f) 7 Jumper wires

g) a 9 volt battery

h) Arduino programming software

Step 3: LED'S

First connect the red led's with the bredboard in a series.

Then connect the yellow led's in a series.

After that the greens.

Step 4: ARDUINO PORTS

The red led's are to be connected to port no.3,the yellows to be connected to port no.4 and the greens to be connected to port no. 5. the negative leads of all led's to be taken common and connected to the nearest ground or Gnd ports.

Step 5: Programing
