JimG:
I saw the caps at the Vr, but assumed they were electrolytics of much higher value. I keep 0.1uF MLCC's handy in my box of jumper wires and use them as close as possible to supply pins of IC's, especially when a breadboard circuit isn't working for unknown reasons.Jim
Thank you, Jim, you are absolutely right, my estimation skills are not as good as they used to be, though they never were in capacitance I guess. They are indeed higher value of 10uF, 0.1uF would not be as good as a decoupling capacitor would it. Could you explain further what is the advantage of the capacitor across the pins, I will try that immediately.
Edit: The capacitor does not seem to affect to anything.
