ATTiny45 Servo8Bit Library Problem

Hi Gang

I've been experimenting with the ATTiny45 and the Servo8Bit Library. All works fine provided I use a small servo. If I try to use a large servo it doesn't work. I've connected everything as per the diagram below.

My hunch is that it has something to do with the clock speed. The ATTiny internal clock runs at 1MHz by default but can be changed to 8MHz (which is recommended and I've done) vs Arduino Uno which is 16MHz. Has anyone experienced a similar problem?

Cheers

Hi Gang

All sorted. The problem appears to be because of two reasons. Bad ground and overheating the ATTiny45 when soldering.
