need help on microswitch output

[blindmind]

i need help. i have connected two micrositches which act like  whiskers, to detect obstacle, to a basic stamps input ports. there is no problem when the output is giving value 1. it gives constant all the time. but, when 0....it fluctuates.not constant 0 instead a combination of 1 and 0 values. so, when this happen...at certain conditions,the motors seem to be stucked, not knowing which direction to go for.


i need to know what can i do to make the 0's to be all zeros instead of the combinations number of 0 and 1.pls help me. im in the state of giving up thinking after tried many attempst to fix it.


thank you

silly me....just ignore this post. the microswitch has three terminals NC, NO and Common.....

i totally forgot to connect either the NO or NC with the ground. after connctd, the 0s are always 0s. muahahahaha
