Send integer from Java Netbeans to Arduino

[philli3]

Hi all,

I'm facing problem from sending integer from Java NetBeans to Arduino Uno Board

Details:
I have created 4 counters at the Java End to calculated the distance moved by RC Car (4 directions)
Let's assume the declared counters are ""Up, Down, Left, Right"

However, when i send the value to arduino board, which is using the serial.read() function, i cannot get the exact outcome (LED Blink) i want.

Any advice or suggestion or tutorials that i can refer to ?

What's your hardware connection?
