Generate 5 volt Power Supply

There is NO 5volt battery in the market!

How to generate a 5volt power supply? Here is the answer!
We can use 8 pieces of 1.5volt battery and arrange in series connection to produce 12volt of power supply (8 x 1.5volt = 12volt). Source the 12volt to a voltage regulator circuit, this circuit will produce 5volt output voltage!
Let get started to do the circuit!

5volt voltage regulator

voltage regulator circuit schematic

First, prepare a voltage regulator 7805, 2 pieces 10 micro farad capacitor, and a breadboard.

Connect the component as shown in the circuit schematic above, make sure the polarity of the capacitor is connected correctly. 

Once the circuit has been completed, check the connection to make sure it is correct.

To test the output voltage, use a multimeter to check the voltage.

In addition, we can connect a LED at the output of the voltage regulator to indicate the output power of the voltage regulator circuit, when a 12volt supply source to the circuit.

connect the + sign to +5vdc.

 Finally the circuit is done!
