Gigantiv Bubble Machine Answered

I am new in electronics.  Can not get the circuitry to work as described in MAKE magazine vol 28.  Has anyone built the bubble machine and can offer me some help.  I sure need it.  Thanks

Seems like a complex build but basics apply here. Is there anything on their site to indicate corrections or tips on how to build it. Do you have all of the correct parts - they use an arduino clone and substitute parts. Do you have good soldering skills and can follow the perfboard diagram and understand which wires just cross and are not connected? It's good to have a voltmeter to check parts of the circuit. Some components may need to be oriented with the correct polarity. You are also dealing with a motor shield, servos and power supply so that makes it more complicated to troubleshoot.

So, maybe you can describe in better detail what is not working. Does the arduino sketch load up correctly and is that working. Do the servos move? Good luck.

Thanks for the reply. I feel certain that one of the suggestions you made will fix the problem. I don't even know if I am misreading the schematic and continue to repeat the same error(s) or I continue to make different mistakes. The Arduino clone seems to be taking the sketch based on the "Hello World" test. The pictures and diagrams in the magazine are not completely understandable to me. If you have access to the article, check and see if they note how current is supposed to reach the remote box. There is no current going to the RJ45 plug that I can see. But that is not the reason things are not working for me. When I test each component by hooking it directly to a power source every component works. However, when I put things together...no luck. The gear motor does not work when I connect it to the L298N H bridge I tried to build the circuit on a breadboard several times before using the perfboard, no luck there either. I can't get the servo or the gear motor to work and I don't think the microswitches are working either. I have not seen any corrections listed on the MAKE magazine website. I would love to find someone that has made the project so I could see how they did things. Thanks for your time I really appreciate it. If you have any further suggestions for me, please forward. I guess I will continue to grope in my electronic darkness and hope the bubble God smiles dowon on me. Larry
