I have a little problem. I have an Arduino Mega, a 128*64 GLCD, a 9V futaba servo (soon there will be another) and a 9V geared motor. The whole is supplied with a regular 9V battery.
When I reset the arduino, my program draws things on the LCD and then operates (at this time) the servo only. And here's the problem: when the servo works, the LCD dims. I think I need a bigger power source? Or something else? What would you recommend? Knowing that I really would like to have only one 9V power supply that my model can carry away.
