Arduino uno power supply 5v 100uf capacitor 2 pieces button 2 pieces 1kω resistor 3 pieces 16 2 characters lcd 2n2222 transistor. Here are some of the other items you will need. Chassis i purchased a plastic project chassis measuring 165mm x120mm x 68mm but of course you can use any box capable of holding your components. Elegoo ac 100v 240v converter adapter dc 9v 1a power supply us plug 5 5mm x 2 5mm 1000ma power adapter wall charger adapter for arduino uno mega with ul fcc ce certificate 4 5 out of 5 stars 221 9 98 9.

Based on lm 317 lm358. Variable voltage 0 25v presize current limiting mode. 2 thoughts on diy arduino variable lab bench power supply 0 30v cc cv m3vuv says. The 5v standby cable is the purple one which will power the arduino and the lcd and also the usb ports so even when the output rails are turned off the monitoring system will still be active and looking for an input on the interrupt pin for the power on button and you can charge your phone without having the entire power supply turned on.

The power supply has the following features. A voltage regulator can be used to supply fixed 5v input to power up the arduino it is possible to power up the arduino using the 5v and gnd pins provided that the input given is steady and regulated 5v. Capable of supplying up to 10a at up to 24v or 5a on each channel. Perfect for my needs.

November 13 2018 at 1 13 am looks like a bit of a con not realy diy in the true sense using chinese moduals sort of cheating. The working and circuit is explained below. February 29 2020 at 4 01 am great work. 0 01 according to the specs of the power supply circuit kit.

I made a custom meter circuit shield for arduino able to measure up to 36v 4a with a resolution of 10mv 1ma that can be used for other projects also.
