how-to build MACKRA a serb variant.

Step 7 The software: arduino

the software consists of two parts : the arduino side, and the computer side. the arduino side is fairly simple, the code for it is as follows:

#include ;
Servo lefttop;
Servo leftbottom;
Servo righttop;
Servo rightbottom;
int incomingByte;
void setup()
{
lefttop.attach(8);
leftbottom.attach(9);
righttop.attach(10);
rightbottom.attach(11);
lefttop.write(90);
leftbottom.write(90);
righttop.write(90);
rightbottom.write(90);
Serial.begin(9600);

}
void loop() // this is were the actual program is finally ran in an infinite loop;
{
if (Serial.available() > 0) { //check for connection
incomingByte = Serial.read(); // if their is data available read it to the incomingByte variable

if(incomingByte=='f')
{
lefttop.write(0);
leftbottom.write(0);
righttop.write(180);
rightbottom.write(180);
}
if(incomingByte=='r')
{
lefttop.write(180);
leftbottom.write(180);
righttop.write(0);
rightbottom.write(0);
}
if(incomingByte=='R')
{
lefttop.write(180);
leftbottom.write(180);
righttop.write(180);
rightbottom.write(180);

}
if(incomingByte=='o')
{
lefttop.write(180);
leftbottom.write(180);
righttop.write(180);
rightbottom.write(180);
delay(250);
lefttop.write(90);
leftbottom.write(90);
righttop.write(90);
rightbottom.write(90);
}
if(incomingByte=='L')
{
lefttop.write(0);
leftbottom.write(0);
righttop.write(0);
rightbottom.write(0);
}
if(incomingByte=='u')
{
lefttop.write(0);
leftbottom.write(0);
righttop.write(0);
rightbottom.write(0);
delay(250);
lefttop.write(90);
leftbottom.write(90);
righttop.write(90);
rightbottom.write(90);
}
if(incomingByte=='s')
{
lefttop.write(90);
leftbottom.write(90);
righttop.write(90);
rightbottom.write(90);
}

}}
