Automatic gate is one of most usefully thing to use in companies, colonies, collages, homes, and
schools. There is some type to operate a gate such as a sliding on screw or on rack and pinion,
piston operated, rotary. Design is available for some type of operation and it is most costly also
When installation and maintenance cost is not yet been considered. The main objective of this
Project is to study, analyze, and provide an enhanced design and performance of power supply,
and also use it to power the automatic gate system. There are different types of mechanism used
to operate gate. Those methods are finite element modeling and mechanical design concept and
In this system, the microcontroller is programmed with a default password. Whenever the right
password is entered using 4x4 keypad. The microcontroller will give command to motor driver,
and DC motor will open and close after some seconds. At the same time, LCD display the
Situation, red LED shows the gate is closed, green LED shows the password is correct. In
addition to this, a push button is added so that you can press it when you are coming out, you
don’t need to password again.
The power supply is of two types, hybrid. There is AC main power stepped down from 220V to
l2V. The DC power is from rechargeable battery, recharged by a lOW solar panel.
The work was successful. It is evidence that the use MCU with the right circuitry can be used to
operate a security system, and the project was effective to give maximum security. So the
implementation rate is inexpensive and it is reasonable by a common person. Hence it can be
afforded to purchase such security gate system to keep your property safe without any worries.
I also recommend to improve on this project by adding other features like, using Bluetooth signal
or remote signal. It can also be a finger print module.
Lastly, I give my further research about the 1 2V rechargeable battery, the circuit needs 9V
battery to be connected together with the AC supply. So my recommendation of further research
is to improve on this circuit so that you can be able to step the 1 2V battery to 9V
