Introduction: Controlling an RC Servo Motor With an Arduino and Two Momentary Switches
The name says it all. Controlling an RC car servo motor with an Arduino and some resistors, jumper wires, and two tactile switches. I made this the second day I got my Arduino, so I'm pretty proud of myself.
Step 1: Parts List
Okay, your going to need the following:
Find out where to buy those here.
Jumper Wires-$8.50 USD
I got mine from Amazon
Resistors- Pennies a piece
Get em from Radio Shack, Digi-Key, Mouser, Jameco, etc.
Your goin to need two around 100 ohms (brown black brown) and two around 10k ohms(brown black orange). These don't have to be exact.
Servo Motor- $10 USD
Yes, I know this isn't the cheapest one on the internet. Tower Hobbies
Breadboard- $9-$30 USD, Depending on the size.
Tactile Switch- $0.20 USD
Only 6,427 left on Digi-Key I just salvaged mine...
Step 2: The Circuit
The circuit is fairly simple. You should be able to throw it on a breadboard in five minutes like I did. Make sure it makes no sense to your less geeky family, and looks like a wad of something you pulled off a drain snake. Yum.
Step 3: The Program/Sketch
if(button7==1 && button6==0)
if(button7==0 && button6==1)
Any bugs, glitches? I don't notice any...
Step 4: It Works(or Doesn't)! And, Coming Soon.....
It hopefully works for you, if it doesn't post a comment. We of the instructable community are usualy good at helping people. Hoping to add a video sometime soon. Might just post a video of an Arduino controlling a servo in another project, since I've moved on to bigger and better things. So have fun with this, modify it, heck go out and make money off of it and then tell me! That would just make my day.
