Today we looked a little bit at servos morors. The Arduino IDE (the programming environment) has a couple of example sketches to be used with servos. Sweep and Knob.
Sweep = https://www.arduino.cc/en/Tutorial/Sweep
Knob = https://www.arduino.cc/en/Tutorial/Knob
Here’s an example of someone using those sketches: https://www.youtube.com/watch?v=jVZJy6OlwcA
In addition, you can have a look at Jeremy Blums, servo tutorial: http://www.jeremyblum.com/2011/01/31/arduino-tutorial-5-motors-and-transistors/
or Jaidyn Edwards who calls himself ‘Chicken Parmy’ https://www.youtube.com/watch?v=XZLVpfydUdw
or 000Plasma000’s video: https://www.youtube.com/watch?v=BfMfysmfoNM
or “How to Arduino #3 – Servos” by Lonnie Honeycutt: https://www.youtube.com/watch?v=ybV8vitYAWU
FOR OUR TowerPro micro Servo 99″ The orange wire is the signal from the Arduino, the red is 5V (from a different supply, best not to use the arduino power supply for motors!) and the brown is 0V. All grounds from different supplies should be connected, but not the (positive)voltages.
I think there are libraries out there have other arduino sketches. You may want to check it out.
Tonight nobody used the L293D and DC motors and the L293D integrated circuit (a ‘H bridge’ on a chip) to allow good control over a DC motor. But if you now want to use this chip,
e.g. Mr “Chicken Parmy” as he calls himself, a.k.a. Jaidyn Edwards https://www.youtube.com/watch?v=XZLVpfydUdw and https://www.youtube.com/watch?v=5nDaHJqruq0
And if you want to undersand the L293D H-brdge chip a bit more, then check out Afratechmods: https://www.youtube.com/watch?v=iYafyPZ15g8
