Arduino LED Matrix Control Part II

With the Arduino app you can control a led matrix over wifi on your iphone.

Later you can save your “icon” and load older ones.

Sourcecode is still a bit clunky. But it Works

- (void)drawRect:(CGRect)rect {
 
	CGContextRef context = UIGraphicsGetCurrentContext();
	if(isOn) {
		[color setFill];
	} else {
		[[UIColor grayColor] setFill];
	}
 
	CGContextSetLineWidth(context, 1.0);
 
	CGContextAddEllipseInRect(context, rect);
	CGContextDrawPath(context, kCGPathFillStroke);
}
