This Report consists of two projects, project 1 which deals with conversion from binary to BCD and vice versa using Shift add-3 algorithm. Project 2 deals with designing a counter that is a microcontroller based that will use two SSDs for display and implement switch debouncing. This counter will count up and down between 00 and 99. The program for both these projects was written an assembly language in MPLAB environment. The code was then inserted into a PIC16F690 microcontroller for imple...

Since the invention of microcontrollers, the production of “smart” electronic devices has since rose drastically. These microcontrollers are put inside a system and act as a brain to control a singular function in a device. This is accomplished by using its central processor to interpret data received from its I/O peripherals. The microcontroller's temporary data is saved in its data memory, where the processor accesses it and decodes and applies the incoming data using instructions st...

This project report about the design, building and implementation of a data logger using a PIC16F690 microcontroller. With the PIC16F690 microcontroller acting as the brain of the system, the data logger was designed and tested. The purpose of this data logger in summary was to store, retrieve temperature and humidity values in the EEPROM of the microcontroller and display on the 20X4 LCD Display. Other functionalities included monitoring of a battery of the system using Buzzer to warm th...

Life has depended mostly on advanced machinery, especially in manufacturing industry. The introduction of computer numerical control (CNC) equipment transformed the manufacturing business by allowing nearly endless sorts of shape to be programmed. When you look at the history of computer numerical control, you can see not only how important it is, but also how quickly manufacturing is changing. Stepper motors and servo motors are the two most common motors used in CNC machine tools [1]. A step...

This report entails the design of a boost converter for a PV array maximum power point tracking (MPPT) system. The system’s main objective is to always extract maximum power from photovoltaic cells. The system uses an incremental conductance MPPT algorithm to track the maximum power of a PV array. A theoretical and literature study that relates to this work was conducted and included in the report. The project feasibility study, and the functional and nonfunctional specifications are listed. T...

This report presents the study, design and making of a power electronic DC-DC converter powering a floodlight load. The wholes system makes up a MPPT solar charge controller. The report comprises of improvements from the first and second phase report. Specifications of solar panel, battery, load and converter are given. MATLAB software is a good choice for modelling and system control, due to that ability it has been selected to design and model the MPPT solar charger. This report shows a comple...
