Number of Projects: 39

Position: Invetor, Designer

Welcome to my Projects Page!

On this page, I will be sharing the things that I created in the path of being a maker. I started building my first robot in 2016, my senior year of middle school. My projects generally include topics like; Robotics, Electronics, IoT, AI, Machine Learning, Rc Vehicles, Sensors, and a lot more. What drives me to build more and more projects is the passion of being a maker and the energy of the maker community. From childhood, I have been tearing down every toy, device, or machine that I got my hands to; this is where I believe my relationship with electronics and robotics has started. The time I started my maker activities is also the time I started sharing them on YouTube and Instagram. I love to share my projects and give back the knowledge I got from the internet to the internet. I am also highly excited about the technologies created by Boston Dynamics, Tesla, ANYmal, DARPA projects … I believe sharing ideas means sharing the passion. Therefore I will always continue to be a part of a community of makers, scientists, and developers.

Arduino Balance Robot with PID / A TUBİTAK 4006 Project

Project Summary: With Arduino, a robot that can stand on two wheels has been developed to make PID (Proportional Integral Derivative) algorithm and its usage more understandable. The robot that was built in the project was made with Arduino and a few basic electronic components, thus making it possible to teach a control algorithm such as PID, which is very difficult to understand in real life and facilitating its practical teaching. The robot, which is formed by combining various components and working on the project, is one of the most suitable platforms since it is one of the easiest systems to understand the PID algorithm. PID algorithm is used in many places today. For example, one of the most common areas is drones, and this algorithm is an essential element for a system that operates with self-balancing logic. In addition, thanks to a Bluetooth module, it was investigated how to adapt Bluetooth control from smartphones to PID systems in the produced robot, and the robot could be controlled by Bluetooth. In this way, both the PID algorithm is applied in the simplest way, and multiple control algorithms are used together.

Project Objective: To facilitate the understanding, teaching, and application of PID (proportional integral derivative) control algorithm by developing a robot that can balance on two wheels. In addition to the PID algorithm, it is also possible to control the robot using the Bluetooth module via the smartphone or tablet, and thus to create a holistic control program by combining multiple control algorithms. The project also aims to explain the PID algorithm in the easiest way, since a robot moving on two wheels has a very simple structure, rotational movement on two axes and production is also very easy. In order to explain the easiest way is provided. With this project, it is thought that the working logic of the technological devices that we hear today, like a drone, can also be clarified easily because it is connected with the PID logic present in the robot that stands on two wheels.

Project Method:Arduino Uno was chosen as the electronic microcontroller in the robot. The general structure of the robot consists of a body with axes at the bottom but standing vertically on the wheels on both sides of the robot. The body of the robot was made by making some modifications to the parts coming out of the robot development kit, and it is made of plexiglass. The power of the robot is provided by a battery consisting of 6 AA alkaline batteries with 9v voltage. Using the L298N in the robot as the motor drive, it enables an easy drive of geared DC motors directly connected to both wheels. Here, Arduino tells the L298N motor driver board with 4 data cables which motor in which direction and intensity will be supplied, and the motor drives the electrical current from the battery by means of some electronic gates, ie transistors, so that the robot can be supplied with the appropriate power. In the stabilization of the robot, data such as angular acceleration is obtained by measuring the equilibrium state of the robot thanks to MPU6050 gyroscope and accelerometer sensor, and processing of these data is provided. The robot is able to stand on two wheels, and this data is processed by the PID control algorithm, and the motors are controlled proportionally. It is also possible for the robot to control the robot via Bluetooth from an application developed by a user for the mobile phone. For this, the HC-06 Bluetooth module was used. Breadboard and jumper cables are used to connect the components in the robot.

Mimouse Wireless Mouse Battery Upgrade

It was time for an hardware update to this wireless mouse with quick-dying AAA batteries. I have installed a battery from an old Samsung phone, which I used for my Rasperry Pi Robot for a long time. I beleive that I will be able to use this mouse for months thanks to the 1000 mAh capacity of this battery (According to my calculations, this time is around 400 hours. The mouse consumes 10mW of power and the battery is 4V.) I also used the Tp4056 module, which has a very low cost as a charging circuit. I think I won’t have to buy a lot of batteries for this mouse anymore.

Arduino, 5110 LCD, and Blynk App

Trying to read the data coming from my smartphone’s brightness sensor with a NodeMcu (esp8266) IoT development board using a 5110 LCD screen over the internet (wifi).😀 And also, I’m controlling the brightness of the screen and a LED on the breadboard just by tapping on buttons and sliding some sliders on the Blynk app. Thus, such a device could be used with some IoT applications via this kind of data transfer, which is limitless of distance and super fast. So there will be some new projects on my page based on esp8266. (Also, I am using the Adafruit’s libraries for the 5110 screens.)

This is a very special project for me. It is a project I just discovered now and a project I made when I was 11 years old (6 years ago). It is one of my first projects and is in the shape of a crane that is made by my efforts to understand the working logic of mechanical tools. It works with the logic of the hydraulic lift system, also known as Pascal’s Principle. It has 4 different axes and 8 syringes that control the movement of these axes and serum hoses that transmit pressure between the syringes.
