AT89C2051 based Capacitance meter

AT89C2051 is the simplified chip of AT89C51, which has only 2 ports. Although AT89c2051 is same as AT89C51 it has an on-chip voltage comparator. With this comparator we can make more additional functions such us analog to digital conversion and so on. In this article an digital capacitance meter has... [More]
