> PS: is 1kΩ enough ? I don't know if it's actually "high value" Well, "high value" is a relative term. In this case we're dealing with CMOS inputs which are quite high in impedance. 1kΩ might be "high" if we were talking TTL. I'd be aiming for at least 10kΩ, maybe 100kΩ. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.
