  • The virtual LED glows to red when I tap on the iPhone.If I enter ‘R’ or ‘r’ manually using cutecom in Ubuntu then the led on the breadboard glows.But when i use the iPhone the led on the breadboard refuses to glow.What may be the problem.The processing starts and the window having the virtual led appears,but there are errors popping.The error is java.lang.NullPointerException at processing.serial.Serial.write(Unknown Source) at processing.serial.Serial.write(Unknown Source) at skecth_dec12a.draw(sketch_dec12a.java:56) at processing.core.PApplet.handleDraw(Unknown Source) at processing.core.PApplet.run(Unknown Source) at java.lang.Thread.run(Thread.java:662) What may be the problem?
