I am making an RGB LED lamp, which you control via Bluetooth using an app on your phone.
I had everything working on a PCB, everything soldered and good to go.
Originally, I was powering the circuit with a 2-way splitter cable (due to changes of plan) and, to tidy it up afterwards, I cut this cable before the split and soldered that, I was, however, surprised to see the green and white cables rather than red and black.
After soldering this, the Arduino I am using powered up fine, but the HC-05 module did not turn on at all, so I took it out and tested it and the Arduino on a breadboard using USB power and it worked fine, so I have nailed it down to a problem with power.
Any help with this?
