Grumpy_Mike:
Read the how to use this forum for advice on posting images, we don’t like going off site for them here.First you have no decoupling capacitors on that circuit. Second Solderless bread board is crap for what you want to do. The connections are unreliable. Use strip board and header sockets and solder it all up to make something more robust, then make a PCB if you want but their is no need.
Well in fact I did provide images in line with the forum entry, but none of them would appear so i edited my post to show the links only.
I already have a perfboard prototype made, but did not want to turn it on again since the bluetooth module fried last time i used it. The breadboard I out together is just to show the forum whats going on more clearly.
The circuit draws around 48 mA by the way.
Where would you place the decoupling capacitors and what capacitors specifically?
