I am using the Arduino Uno with SerLCD (3pins), i connect the LCD Vdd to the Uno 5V, GND to GND, and LCD RX to the Uno TX which is at pin digital (PWM (1)). I am using the SoftwareSerial Example, i change the baud rate to 9600. Everytime i upload the code it gave me a bunch of characters as soon as i unplug it and plug i it back i see the right output. Can anyone help please!!!

Receives from the hardware serial, sends to software serial.
Receives from software serial, sends to hardware serial.
The circuit:
* RX is digital pin 2 (connect to TX of other device)
* TX is digital pin 3 (connect to RX of other device)
