First Robot: Sound + Servo!?
October 6, 2012
So I'm trying to adapt my robot to make a wake up robot, that makes an alarm, and as soon as the alarm starts, he starts driving so u have to get up to shut him off.
I've put all my components (Battery holder, print board, speaker, motors and sensor) on a Lego base board, and changed the resistor array by the Darlington to make a louder sound. Now today I wanted to add my servo to my front wheels (just & double Lego wheel now), to make turning more comfortable. But it just doesn't want to work. It's really impossible to add the servo without the resistor array? I replaced it by the Darlington, it works, but then my alarm sound is really silent, not really something that can be heard while asleep. So the Darlington is really necessary.
So my question: Is it impossible to get an active servo without the resistor array chip? Do I need a second print board? (please say no :P)
Thanks in advance
