Begin by printing the data sheets and all the documentation you can find on-line for your components and putting them in a file folder. Now, create a spread sheet with a line for each component in your project. Make a column for the voltage required for each component. Make another column for the current requirements for each component.Are all the voltages the same? Probably not. Pick the highest voltage and this will give you a beginning voltage so you can get a power supply for your project. Add up the current requirements for each component and double it. This will be the current requirements for your project. Get the appropriate power supply.Paul
