Hello evryone.I just bought my first arduino and started to play with it.Done all of starting tutorials no making a foward backward conntrol control using c#
just after i uploaded my processing code to arduino and launched applicatinon my buttons send signal non stop.Means that my motors keeps on spinning but i wabt them to spinn just until button is pressed and affter i reales it i want motor to stop. My arduino skech is
// set the output pins
// 14-18 are actually analog pins 0-4
int baseMotorEnablePin = 2;
int baseMotorPin1 = 3;
int baseMotorPin2 = 4;
int shoulderMotorEnablePin = 14;
int shoulderMotorPin1 = 15;
int shoulderMotorPin2 = 16;
int elbowMotorEnablePin = 8;
int elbowMotorPin1 = 9;
int elbowMotorPin2 = 10;
int wristMotorEnablePin = 5;
int wristMotorPin1 = 6;
int wristMotorPin2 = 7;
int handMotorEnablePin = 11;
int handMotorPin1 = 17;
int handMotorPin2 = 18;
// set a variable to store the byte sent from the serial port
int incomingByte;
void setup() {
// set the SN754410 pins as outputs:
pinMode(baseMotorPin1, OUTPUT);
pinMode(baseMotorPin2, OUTPUT);
pinMode(baseMotorEnablePin, OUTPUT);
digitalWrite(baseMotorEnablePin, HIGH);

pinMode(handMotorEnablePin, OUTPUT);
digitalWrite(handMotorEnablePin, HIGH);
// start sending data at 9600 baud rate
Serial.begin(9600);
}
void loop() {
// check that there's something in the serial buffer
if (Serial.available() > 0) {
// read the byte and store it in our variable
// the byte sent is actually an ascii value
incomingByte = Serial.read();
// note the upper casing of each letter!
// each letter turns a motor different way.
if (incomingByte == 'Q') {
digitalWrite(baseMotorPin1, LOW);

}
