I am working with gesture controlled robot..my accelerometer works fine..i have checked it using arduino uno..bt when I am using adxl335 i.e my accelerometer with a comparator i.e lm324 then I am not sure if things are going fine or not... Means how do I check if comparator is giving right output or ht12e i.e encoder is working fine or my rf unit? Because I am nt able to get output..and I am confused that which value actually changes when comparator or any component gives output...is it current or voltage or something else..
