This is a project done for an introduction to electronics course.
[This is my open notebook for the course: http://mbenitez.iheartanthony.com/]
It's a really simple project combining a pushbutton, an arduino uno, and some LEDs.
The project I meant to do in the first place was to use the LEDs as turn signals but I don't know how to program this ...yet.
The main problems I have with programming are incorporating a second push button while making the LEDs blink.
For now, this is something I can do successfully.
However, I really want to branch off of this so any feedback is sooo very appreciated!!
Tools you're going to use:
Stuff you're going to need:
-DC coaxial plug 2.5mm x 5.5mm
-9V Battery Snap Connectors
-4 x LEDs (5mm, 2.6 Volt, 28mA)
-Push Button Switch (Screw Terminal, 15A- 125 VAC, 10 A -250VAC)
-10 x small jumper wire
Step 1: Arduino Battery Pack
To arm the arduino battery pack I followed this video: http://www.youtube.com/watch?v=zr-sVHnUACw
If you don't care whether your soldering comes out perfect or not, or if you're new to soldering (like me), a good way to ensure that you get a good connection is by placing the soldering gun on what you want to solder and just get a glob of solder enough to cover it.
Not very elegant, but it works!
Anyway, to solder this you want to thread the wires from the battery snap connectors into the DC coaxial plug so that when it's soldered it's pretty sturdy and won't come off.
You then slip the cover on and snap it onto the 9V battery.
