64 Make: Robotic Arms
STEP 3
Next, we’ll need to recreate one of our previous circuits by wiring up two
servo motors to our Arduino. Just as before, we’ll be using pins 3 and 5
(Figure
3-15
).
Once you have written the code, upload it. If all goes to plan, you should now
be able to tell your robotic arm exactly where it needs to be. Feel free to have
some fun updating the desired coordinate to test out a few positions.
WRAPPING THINGS UP
In this chapter, we started with a simple question: Is there a way to
program our robotic arm to reach a specific position in space? The answer
is, absolutely. Through the magic of inverse-kinematics equations, we ...
