Question For Carl

[William]

I am using a cmos tlc555ip for ic5 timer. I am not getting .5v with both resistors centered but I can get .5v if I adjust them to a different position. The tlc555ip has higher input impedance and specs say that it will use less capacitance than the ne555, will this cause the voltages to very? I am getting a .264v reading when centering the adjustments. Thanks William

Hi. William I am using NE555cp and I am not getting .5V with both resistors centered and I am getting .25V and I Know its normal, my progect lose sensivility a few seconds in not feedback mode.

Re: Question For Carl

Thanks for the information Serafin, I have not gotten my project completed yet, I am just to the clocking circuitry. I can not help with the lose of sensitivity you are having, but there is something about it in the article for PI-1 Carl put on the project page. Thanks William
