So I'm building a project with a cmoy inside it. I'm using tangent's resistive voltage divider to power everything. In addition to the cmoy I have a CD4052 Mux and a DS1802 digital pot for volume control. All of these work perfectly fine and sounds amazing,
However there is one last problem, powering a microcontroller. Right now I have an arduino uno while I prototype and when I plug in the +9V into its regulator the rail voltages are lowered to like 3-4V. I'm guessing its because the uC is a much larger load than anything I have right now but I dont know what to do about it.
So any ideas on fixes, hopefully as cheap as possible.
Also, I feel like a noob for asking this but how do I measure the amount of current drawn by this design. I was looking at some of the other virtual ground setup's over at tangents and the biggest factor is current draw. I tried disconnecting on side of the transfromer and putting the meter in sereis. However none of the power LEDs light and the meter reads like 2A while the transformer is rated for 24V, 500mA.
