Sir total price or what is the sapping market name

How to measure how much current it is giving outout???

[@singhprojects]

At the output of the DC-DC buck converter you can use the AMP/Volt Meter as shown in this circuit diagram. If you find it little tedious, then let me know I will show you a simpler example. Example: www.technotaj.com/2021/07/06/best-variable-power-supply-circuit/

[@whitehacker6171]

@@singhprojects then what is the use of the current control of the buck converter??

[@singhprojects]

@@whitehacker6171 The use of Current Controller (Trimpot) on the buck converter is to adjust the current for the device that you want to use with it. example, an amplifier, radio or Arduino board etc... However, I have replaced these (Current limiting Trimpot) and (Voltage limiting Trimpot) with equivalent value Multi-Turn potentiometers as I want to use this buck converter as a regulated power supply - so that I can use it externally with hands and not through screwdrivers. 🤘This gives me flexibility to change the current value and voltage even when the buck converter is fixed in a container box.

@@singhprojects i watched many videos, i saw in all of them that they can't control the current output using the cc screw.. Can u suggest me a video where they show it can be controlled??
