Just the integrated LM2576-5 contains all the elements to build a switching power supply, just add an inductor, a diode and a capacitor. It can deliver a maximum current of 3A and accepts input voltages between 4 and 40volt.
I'm going to build a spider robot inspired by the project featured here:[...]My problem is that I don't understand exactly how to do all of this. I don't think I can make a circuit board like they did. Their board incorporates several resisters, an inductor, capacitor, diode, etc. Can anyone help me wrap my head around this? [...]I'm not sure exactly what else I need, and how I should put it together.
I'm going to build a spider robot inspired by the project featured here:http://www.open-electronics.org/robot-shield-for-arduino/ Like their robot, mine will use an arduino uno, 8 servo motors, clicking here and an ultrasonic range detector. I have some experience programming, but I have almost no experience with electronics. I understand that I need to provide stable voltage to my servo motors. I plan to use a 2A li-po battery pack, the same LM2576-5 voltage they used before the servos, and to go direct out of the battery pack to the arduino. My problem is that I don't understand exactly how to do all of this. I don't think I can make a circuit board like they did. Their board incorporates several resisters, an inductor, capacitor, diode, etc. Can anyone help me wrap my head around this? I'm just a little confused. I have a shopping cart with 8 servo motors, an LM2576-5, and a battery pack in it. I'm not sure exactly what else I need, and how I should put it together.
