Code

Arduino Code to control Motor Speed via PedalArduino
#define PIN_Pot			A0
#define PIN_LED			9
#define PIN_Input1	2 //L293D pin 2
#define PIN_Input2	7 //L293D pin 7
#define PIN_Speed		3 //L293D pin 1

int sensorValue = 0;

void setup()
{
	pinMode(PIN_Speed, OUTPUT);
	pinMode(PIN_LED, OUTPUT);
	pinMode(PIN_Input1, OUTPUT);
	pinMode(PIN_Input2, OUTPUT);
}

void loop()
{
	sensorValue = analogRead(PIN_Pot)/4;
	
	analogWrite(PIN_LED, map(sensorValue, 0, 255, 10, 255));
	analogWrite(PIN_Speed, map(sensorValue, 0, 255, 50, 220));
	
	//Setting the direction of the DC Motor
	digitalWrite(PIN_Input1, LOW);
	digitalWrite(PIN_Input2, HIGH);
}
