Discover how to craft a straightforward gear indicator for manual car transmissions. Utilizing an Arduino UNO and an SSD1306 128x64px IIC OLED screen, along with 4 Hall Sensors, the tutorial demonstrates how to gauge gear position by detecting the magnetic field of a magnet affixed to the shifter handle.
Images, created in Photopea, are converted into C-style arrays via Image2cpp for seamless integration. For simulation purposes on WOKWI, potentiometers substitute Hall sensors. Additionally, viewers will learn how to design a custom PCB for this project in KiCad. Gather some wires and a breadboard if you're keen to replicate the project. Best of luck with your endeavor!

The Rust is a perspective programming language that steadily gains its popularity but not in embedded systems. Despite the benefits that the Rust brings (such as memory safety), not many companies are using it yet. Instead, they tend to stick to C or C++, because they've already invested a lot of money on writing firmware in this languages and are hesitant to change.
Startups are more interested in Rust because they don't have any old systems to worry about, but bigger companies are taking their time to see if Rust is worth it. Learning Rust can be tough, and not many companies are offering support for it. However, as the need for safer languages grows, especially with the rise of IoT, Rust might become more popular in the future. Its role in embedded systems remains uncertain for now, but it could change over time.

The project focuses on utilizing the Persistence of Vision (POV) principle to create a high-resolution POV display capable of showing images and animations. It employs an ESP32 module as the main controller, with two rotating arms each containing 64 LEDs, resulting in a total resolution of 128 pixels.
The circuit utilizes components like shift registers, MOSFETs, and hall effect sensors, regulated by an AMS1117 (a popular voltage regulator). The ESP32 handles display synchronization and control, while the PCB design includes provisions for sensor integration.

ONE is a self-balancing unicycle robot project based on IMU technology and STM32 microcontrollers. The core of the system is orchestrated by two PWM channels for motor control, two timers dedicated to encoder data retrieval, and several Analog-to-Digital Converter (ADC) channels facilitating the capture of analog gyro and accelerometer data.
Within the repository, you'll discover the firmware source code tailored for STM32 microcontrollers alongside detailed 3D models of the mechanical structure. While the circuit board schematics have is missing, the underlying circuitry remains straightforward and would not be a challenge for a skilled electrical engineer.
