Most ammeter installed in equipment panels such as distribution substations in Nigeria are mainly analogue meters of which many of them are currently in a state of disrepair. Noteworthy, also is that most of the ammeters are foreign made and thus huge foreign exchange is needed to replace them. Thus, there is need to develop locally made alternatives for the meters. The aim of this project is to design and construct a battery powered digital ammeter with liquid crystal display (LCD). The ammeter designed in this work named “JP AMMETER”, implemented using embedded system design. PIC16F876A microcontroller was used as embedded system control unit. The ZMCT103C current transformer with a range of 0 10 amps, was used as the current sensor which produces the analogue voltage signal representing the current being measured. The output of the current sensor is connected to the analogue to digital (ADC) pin of the microcontroller. The ammeter was designed to work with a
