The main reason Teensy is preferred for DIY keyboards is its native USB support. Unlike most Arduino boards (like Uno, Nano, Pro Mini) that use a sepa...

A single Li-ion cell can swing from about 4.2 V when full to 3.0 V when empty, which is fine for parts designed for that range but dangerous for stric...

This usually happens due to the high sensitivity of the multimeter’s continuity mode. Some meters are designed to beep even with very low resistance, ...

I've tested several ESP32 boards, both branded and ultra-cheap clones, for basic IoT projects like Wi-Fi control, sensor data logging, and general exp...

Grounding is crucial in electronics for safety, circuit stability, and performance. It provides a safe path for fault currents, preventing electric sh...

I would recommend the STM32 for its robust peripherals, low power consumption, and scalability in industrial or high-performance applications.

@ankunegi I want to control only one motor. Using a driver module is an overkill I guess. Is there a way to make it compact? Any other options?

I totally agree with Jeff. Building a custom PCB including a microcontroller chip for a personal project such as automating your room is one thing and...
