This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Working with graphics on microcontrollers has always meant focusing on making the most of limited resources. Particularly in the 8-bit era, all manner of tricks were used to get low-performance chips ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

We’ve seen a few H-bridge circuits around these parts before, and here’s another application. This time we have an Old Train ...

This section provides the wiring guide for connecting a 2.8inch TFT display based on ILI9341 to an ESP32 development board. The table below outlines the pin connections for the display and touch ...

Additional circuitry required. One Diode (I use 1n4004) - pole/cathode at tx pin other at rx pin. 4k7 Ohm resistor between rx and 5V (3.3V also works). Same at the other microcontroller but you don't ...
