If you use an infinite impulse response filter, it is very simple to do:

new_filtered_value = K*previous_filtered_value + (1-K)* new_sample

... that's all there is to it.

"K" is a tuning constant, which you use to adjust the "strength" of the filter. K must be in the range zero to +1. When K=0, there is no filtering. When K=1, the filtering is so "strong" that the filtered value never changes.
