Arduino UNO With On / Off Module Switch + Battery Advice

Question

So I have the following connected and the programming works fine when connect by USB

The Parts

• 1 Arduino UNO
• 1 Laser Module (KEYS)
• 1 Rocker Switch Module (Standard 3 PIN)
• 2 Variation Motors (KEYS)
• 1 Speaker Module (BIG SPEAKER MODULE)
• 2 Push Button Modules (Standard 3 PIN)
• 1 SD Card Reader Module (Generic)
• 1 3V 1800 amh Battery

The Problem 1 I want to make an On/Off Switch but it doesn't work.

PROBLEM 1: Why doesn't this work when it does for the Nano I have here:

Secondly Here are some pictures of the setup I have

The Problem 2 I need advice on what size battery to use the project for 1-2 hours I think I need (5v,7v,9v) but would like some help with which would be best suited or any suggestions you have

What I think it is but need help

1. The Wiring is wrong (but I have tested it all and its working fine)
2. The Rocker Module is passing 3V to the UNO (Not enough Power)
3. The Battery is not powerful enough (I need a bigger battery)
4. NOOB Problems as its my first project

What I need help with

1. What battery to use?
2. Making the On/Off switch work

Thanks for the HELP!!!

• chrisl: Please link to the switch product, that you used. An image is not enough here. We beed to know, how the board uses the switch. Is it just a breakout board for the 3 switch pins or are there other electronics on it? Also please put the images directly in the question, not on an external site. And some of the images are not in focus or rather dark. Please provide good in-focus pictures, so that we can actually see something in them
• Gil: Good starting project, You need to understand how a switch works, your first does not work you short the battery, draining it very fast. You need only two connections to the switch. Run ground to ground, battery to center pin and arduino to NO pin. Let us know if that works. You can view a few basic electronics tutorials, that will help. Remember we all started the same place you are. Most important have fun!
• Davinco: geekbuying.com/item/… this is the rocker
• Davinco: can confirm its definitly the 2 mode rocker that is wrong.......... as i have just tried it with a push switch to test it. and works fine haha. I tried what you said and the rocker switch does work either (SIG/VCC/GND) connect battery to VCC and SIG to arduino still nothing

Answer 1

So here is the deal (I Kinda Solved It) so I took apart a 9V battery pack with a flip switch in it..... soldered some wired to it and now it works perfectly...... haha

but I would still like the know the reason why the rocker switch module doesn't work.

the only thing I can think of is the Voltage or Amp passed from the Switch Module isn't enough to power the board (as I tried 3 different rocker switches and all acted the same)

Thanks for the help
