Week 0 - Journal

i wanted to make smart parking gate

it has 2 led indicators to enter the gate or not

and button to open the gate to let the car cross

then it closes again

i used tinker cad to draw the circuit and adding the components

i used

-arduino uno

-servo motor

- ir sensor

- push button

- 2 leds

- bread board

i connected the leds green in pin 5 , and red in pin 5 thru 220 ohm resistors and ground from the bread board

and the leds will be output component

the servo motor ground and volt from the bread board and the signal to pin 7 as output component

the ir sensor ground and volt from the bread board and the signal in pin 4 as input component

and push button to ground and pin 12

i started the code by attaching the servo library

then the integers to my components

and define the pins which one is input and which one is out put

at first i told the code if the gate is empty and the ir sensor not detecting and objects turn on the green led

and if it detect anything turn on the red led

and if the car driver pushed the button

open the gate by letting the servo rotate to 90 degree then delay two seconds then move back to 180 degree

there was a problem in adding delay in the servo movement

to let the gate opened a little bit till the car entered

and i searched in arduino.cc and found the solution

by adding the delay between the first move and the second move

i succeed in completing the smart home activity with eman

after failing in the first time at home
