Programmable Dc Power Supply Using Arduino

Glad to see you have arrived on this page to learn how to build a programmable constant direct current dummy load.

Programmable dc power supply using arduino. Circuit diagram and working explanation. To further simplify it s building we succeed to reduce number of wiring to the minimum. This dc voltage is regulated to our required level by using lm338k and controlled by using a potentiometer. Arduino uno is an open source platform which is used to develop electronics project.

The arduino uno clone atmega328p is connected with 2 interrupt based user input switch an elegant oled output display. It is featured with 3 3 to 30v adjustable range and 0 5 to 3a current limiter with 0 5a steps. In this project we will learn about the four different ways in which we can power up the arduino uno while making any arduino projects it is necessary to know these techniques since there are instances when flexibility with regards to the power supply is required. Arduino programmable constant current power resistance dummy load.

It comes with a bunch of features you can check on the link below. The programmable bench power supply project was an attempt to create reliable modular open and programmable power supply that can be used for various tasks starting. Power module 2 is required per unit arduino shield for digital control. The circuit for variable voltage unit using arduino is shown in below diagram.

This load will allow you to draw a set current from any source. Using a xl6009 dc dc boost module first we make 15 6 volts from the li po. Source of power is the 3 7 v li po battery which is usb rechargeable. The power supply is controlled by an arduino and a touchscreen tft screen is used to monitor and control it.

This load can also be set to a constant resistance or a constant power. To run the mcu we also make a 5 volt using 7805 regulator. As an power input it s possible to use affordable toroidal transformer with dual secondary coils or two 48 v ac dc modules. Atmel studio 6 2 or aurdino nightly.

Arduino uno power supply 5v 100uf capacitor 2 pieces button 2 pieces 1kω resistor 3 pieces 16 2 characters lcd 2n2222 transistor. With having different specification according to their use. The arduino uno has undergone many revisions and hence the arduino power supply circuit has evolved to an almost foolproof design. It can be easily programmed erased and reprogrammed at any instant of the time.

It can withstand infinite.
