This is Parking System with Ethernet and in arduino.
Ethernet is WIZnet W5500 Ethernet shiled.
It is very easy possible using the ethernet. Ethernet or internet is originally using TCP/IP Protocol communication.
And originally TCP/IP Stack is Software. But, W5500 is solved TCP/IP Protocol 4 Layer.
So, It is very easy possible ethernet.
Step 1: Component List
1. Arduino Uno
2. WIZnet W5500 Ethernet shield
3. Ultra Sonic Sensor(HC-SR04)
4. Servo motor (SG-90)
5. infrared rays sensor (GP2Y0A41SK0F)
6. Bread board
Step 2: Hardware Make Process
It is make process.
1. Make Schematic
2. Sensor verification
3. Source coding
4. Make Hardware case
