The electronic projects involve designing and building a functional device using electrical components like resistors, capacitors, transistors, microcontrollers, and sensors. These projects help learners and hobbyists develop practical skills in circuit design, programming, and problem-solving while exploring various applications in areas such as automation, communication, and IoT (Internet of Things).
This project will share with you how to make an ESP8266 drone (this drone can climb walls) and how it works. We all know what the function of a drone is, which is to fly. If I tell you that this drone can climb up a wall or go underwater like a submarine, you will …
MAKER: Chen Liang Strider is a mechanical walking robot developed by Wade Vagle. It is a reptile robot based on ESP32 camera and 3D printed body with flexible and convenient movement speed. It has undergone many iterations and continuously optimized its movement speed. Before building this robot, I also tried to build another robot, Lego Trotbot. …
Over the past few months I have been researching how to make a weather station that is energy efficient and small in size. I want it to sit on a window frame and be charged by sunlight during the day. Here are the details about the components needed for this project: The conceptual diagram above …

Introduction After defending his master’s thesis, the author used his free time to create a robot he had always wanted to make – a cute and useless robot. The useless robot principle is a motor connected to a switch, controlled by a logic gate. When the switch is pushed to “on”, the robot activates the …
This is yet another FM transmitter DIY kit for beginners and hobbyists. It is slightly different from our previous FM transmitters. It has 3 NPN transistors and the transmission range is around 50-100 meters. Current 5-15mA Working voltage DC 3-6V ** From experiments, it can be used with 9 volts. Transmission distance 5-50 meters Transmission frequency …

LM317 and PWM control from Arduino There are very inexpensive ready-made voltage regulator modules, that is, a stabilizer based on LM317 chips . Here is a schematic diagram of the assembly and connection of such a module or a separate LM317 chip: Since this block follows the typical LM317 application circuit, it is great for powering …
UART PROTOCOL: DESCRIPTION OF WORK UART (Universal Asynchronous Transmitter Receiver) is the most common protocol used for full duplex serial communications. The device sends and receives data from one system to another. In this manual, we will study in detail the basics of communication and the operation of the UART protocol, a detailed description of the interface …
LC METER In the world of radio amateurs, especially during repairs and building a new devices, you should have a device for measuring of capacitance and inductance, this device is called LC meter. Today, on the Internet, you can find many schemes of such devices, complex and very expansive. But you can create your own …
