DESIGN AND CONSTRUCTION OF BATTERY LEVEL INDICATOR
We dedicate this project work to Almighty God, the source of all knowledge, wisdom and understanding, for being there for us throughout the period of our study and to our lovely parents, Mr. and Mrs. Abido, and Sir & Lady Christopher Korugbo for their parental care, who has always been our inspiration.
Thanks to God Almighty, the source and supplier of all potential, the father of all creation for the privilege to go through our first degree without Him, nothing would have been accomplished. Our sincere and profound gratitude to our affectionate parents, Sir & Lady Korugbo, and Mr. & Mrs. Abido and our siblings for their moral, spiritual and financial support. May God bless you all.
Special thanks go to our gentle and impeccable supervisor, DR. C.E MOKOBIA, for his efforts, advice, fatherly love, corrections and knowledge in carrying out this research work.
Our appreciation also goes to the Head of Department Dr. ARTHUR EKPEKPO, all our lecturers and staff of the Department of Physics for their impartation and to all those who contributed to this work in one way or the other.
We will not fail to appreciate the efforts of our friends especially, Joshua, Favour and Osas, loved ones and all those who contributed to the success of this research work, we are indeed grateful. May God richly bless you all Amen.

Normally, in mobile phones, the battery level is shown in dot or bar form. This lets us recognize the battery level. Here we present a circuit that lets us know the battery level of a device from the number of LED s that are glowing It uses 10 LED’s in all. In this we used LM3914 IC…….
