13-Coffee Mixer
I made this coffee mixer not to use spoon
. this is very funny and besides it can make the coffe or tea very sweet with a little sugar. it has a dc motor, a button and 2 magnets
12-Resistor Calculation
I made this to calculate the values of resistors, I made it completely myself,it is so easy to use, useful

11-Explorer car(H bridge)
This car was a graduation project which passed with good grade. The design and system of car are comletely belongs my friend called Özkan
except motor direction control system it means h bridge system. As you see there are 6 dc motor but 2 motors were connected to other 2 motors as paralel because 2 l293 h bridges was used besides 1 16f84a was used to control the h bridges
10-Saving the electricity
This system was designed to save extra electricity, system switches off or switches on the electricty of devices by counting the number of people, if there is one person and more than one, system swicthes on devices or if there is no one in the room, it switches off the devices, as you see there is a lamp on the door, it referres to the devices in room,for counting processing, two ldrs and two lasers were used to count people,the reason of usage of 2ldrs and lasers is to define the enterance and exits,the idea and making of the system are completely belong to me
9-Night Rider
This project is very easy project to do, its microcontroller is 16f84 and it has very easy codes to write programs in pic basic pro, the lights can go from left and right, the combinations can be changed.
8-Door lock by password
This system was given by me by using 16f84 pic and the code was written in pic basic pro,the password is consisting of four numbers, the door is opend by using a magnetic body, I set this system on my dormitory's room, I have used it for 1 month and in the end, I got 2 alert from managementof dormitory and management of campus.
7-Water level control (3. version)
there wasn't used relay in this system like I made before. This works with analog digital converter, there is an alarm in this system when the level of water comes to last level ,the alarm bips. It is still being used in my home
6-Water level control (2. version)
16f877 microcontroller, 2*16 lcd, 5 relays(for 5 levels) were used as basic. In the screen, the level of water is seen as symbol of % and graphical. It was designed as 5 levels but the numbers of levels can be enhanced besides there is an output for motor pump(12v) to fill water into tank, the motor is activated as manual but, it is be stoped again as manual or when the water is in last level (it means when the tank is full) it again stops.
This project is compeletely prototype, however with some chances, it can be used for real system(220 volt AC water pump)
5-Water level control (1. version)
I made this system for my house to see how much water in the water tank (1 ton). it shows the 4 level,
when the press the yellow button the leds swithches on according to the levels in tank. it is working with 9 volt dac nd there is no resistor no transistor and no complex a structure
4-Automatic plant watering
I made this system for my teacher called Mehtap hoca in my university. it has a 1,5 liters of water capacity.when the soil is dry (no water), the system starts to water the soil until the system feels the water between two wires in soil.The amount of water can be adjusted.
3- Digital Clock
This clock system is as large as four A4 papers, the the clock circuit is not belong to me, I just made the seven segments and their design(resistor, calculation, pcb),I used bc547 transistor to drive the leds. I made this system for campus in my university
