About: Hello~ I'm a Seoul Robot High School student. Nice to meet you.

I made ARDUINO bluetooth car by LEGO.

It is very simple and cheep.

Let's start making!!

Step 1: Material

If you don't have It, you can use another things.

Step 2: Install Program

Install TeraTerm and arduino1.6.7v or arduino1.0.5v.

And copy this code.

void setup() {
Serial.begin(9600);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
}
void loop() {
if (Serial.available()){
byte data;
data = Serial.read();
if(data=='w') //press 'w' forward
{
digitalWrite(2, HIGH);
digitalWrite(3, HIGH);
}
else if(data=='a') //press 'a' left
{
digitalWrite(2, LOW);
digitalWrite(3, HIGH);
}
else if(data=='d') //press 'd' right
{
digitalWrite(2, HIGH);
digitalWrite(3, LOW);
}
else //press another botton stop
{
digitalWrite(2, LOW);
digitalWrite(3, LOW);
}
}
}
