At first I should tell something. I had not beautiful pictures. So, I have taken the pictures from bildr.blog.
We know, an Arduino UNO has not much pwm pins to control many servoes. So, we often fall in a problem to control more servoes by an arduino. Today, I will explain you how can you control a lot of servoes woth arduino. So, let's started.
Step 1: Gather Materials
You will must need an arduino, you know. Then, you will need a breakout board for pwm pins. It's name is TLC5940 breakout board. Here is the list -
1. Arduino UNO R3
2. TLC5940 breakout board
3. 5 volt adapter
4. As much servo as you want to control
Step 2: Circuit Diagram
Here is the circuit. Connect them by jumper cables.
Step 3: More Servoes!
You can connect only 16 servoes with a TLC5940 breakout board. But if you want to control more servoes you can follow this circuit diagram. And now, controlling a lot of servoes is not will be a matter to you. Will not it!
Step 4: Thanks!
But you should not stop here. You can make a humanoid robot and more by this idea!! Here is an URL for making humanoid robot
Thanks a lot!
