TRAFFIC SIGNAL Using Microbit

HI FRIENDS ,

I made a traffic signal using microbit in tinker cad

Components used :

* microbit

* led nos : 3

* resistor nos:3

1 microbit

3 resistors

1 red colour led, 1 yellow colour led , 1 green colour led

We have to connect all the led 's cathode to the ground of microbit

connect all the led 's anode to the resistor and each resistor is connected to each pins as follows

resistor no 1 to pin no 0

resistor no 2 to pin no 1

resistor no 3 to pin no 2

On start block the coding is: show string TRAFFIC SIGNAL– it displays traffic signal in the microbit with the use of the leds.

In the forever block the coding is:

to on the digital write pin2 ( green colour led) and show GO! On the microbit

then wait for 5 sec after 5 sec off the digital write pin2 (green colour led)

then to on the digital write pin 1 (yellow colour led) and display WAIT on the microbit

and wait for 2 sec and after 2 sec to off the digital write pin 1 (yellow colour led)

then to on the digital write pin 0 ( red colour led) and to show STOP on the microbit

and to wait for 4 sec after 4 sec to off the digital write pin 0

this coding will continues in forever block

I hope you like my traffic signal project
