Whenever it comes to any Arduino related project. Everyone needs a power supply to juice up their projects. Some people like me uses ordinary mobile chargers and some likes to use a 9v battery and few go with a LiPo battery. But I have a better way!!! Why don’t we just make our own power supply?? Even its cheaper than a traditional mobile charger yet with more flexibility. Today we are going to make a really small and cheap Linear Power Supply which will give output of 5v but by replacing only few components we can get 12 or 9v easily. Components Needed Four diodes Two capacitors One transformer One led One resistance One 7805 ic (If we just change the transformer and the 7805 IC to 7812, we can get an output of 12v.) Circuit Designing Let’s learn how to make a linear power supply step by step. First…
