A circuit getting 12V and 4A supply which was broken into 2 parts with the help of XL4015 module (converter) which provide 9V and LM2596 module (converter) which provide 5V , further we are using a microcontroller and three L298N to run three stepper motors having same configuration because it was required that we have to run the motor in such a way that it should take small steps (micro steps) at the same time there is a problem that L298N got too heat when this circuit run a time period of 4-5 hours such that our circuit stop working but we required a circuit that can work for 10 hours continuously non stop with a good life cycle. This circuit also give fluctuations at different stages like when 12V was converting in 9V and when 9V was further converting in 5v. In this complete circuit we required at least two 5V connector and a 9V connector so that we can connect our external LED and a fan with it.
