    I would like to make an Arduino system with mp3.sound and 2 LED output. 3 conditions in the program: Either pressing one or two microswitch all together, there is not any output. Release the microswitch, the mp3 sound will play and the red led will change to green. Now I need someone to help me set up the program and hardware part.

    The project: To design and prototype PCB and circuit with great attention to low power consumption and low component costs. Stage 1 I have 2 micro gear brush motors that will be running on 6v dc (4X AA batteries) they use 40ma on free run and 700ma at stall, these will be fitted into a unit called project X I need to be able to control them by remote control both forward and backwards so I assume that would be ...

    I have a circuit schematic that I did on eagle. I want to make sure that there will be enough power for all of the components, that I have the components hooked up correctly, and make sure that there are no shorts. I have datasheets for the components I am using. If a component needs to be replaced, I would like to know which component and where I can find it. Also, if the voltage is incorrect, I would like ...
