I am building the e-bike of kayaks. So how do you control a DIY electric kayak? With a phone app? With a remote control? All while trying to hold a kayak paddle? I wanted the user interface to feel as natural as possible without removing you from the actual experience of kayaking. This Instructable shows …

A Schmitt Trigger is a very practical circuit that helps eliminate switching noise on an input signal by implementing what is called hysteresis. Imagine you have a system that feeds a 0 – 5V signal into a rising/falling edge GPIO interrupt. With no Schmitt Trigger, the interrupt would trigger anytime the signal rises or falls …
The STM32 HAL (Hardware Abstraction Layer) speeds up development cycles, makes switching between STM32 processors a breeze and has a huge support community. The HAL is part of the STM32CubeIDE tool set which allows users to auto-generate code for various STM32 peripherals. The HAL can be thought of as a highly abstracted library which is …
Although UARTs (Universal Asynchronous Receiver Transmitter) are one of the easiest ways to communicate with a microcontroller, there are many incompatible standards, converters and cables to figure out. Sorting through all of this as a new engineer can be overwhelming. This post will teach you everything you need to know about UART vs RS232 and …
