Developed by ARM, the latest C/C++ compiler “ARM Compiler 6” had been announced with a safety package in a move to help developers to meet functional safety requirements. ARM Compiler 6 is based on the modern LLVM framework and Clang technology, in close collaboration with processor and architecture projects to best utilize every new hardware feature. […]
10km ESP32 WiFi Using Directional Antenna
https://www.electronics-lab.com/10km-esp32-wifi-using-directional-antenna/
[Jeija] was playing with some ESP32s and in true hacker fashion, he wondered how far he could pull them apart and still get data flowing. His video answer to that question covers the Friis equation and has a lot of good examples of using the equation, decibels, and even a practical example that covers about […]
MightyWatt: 70W Electronic Load for Arduino
https://www.electronics-lab.com/mightywatt-70w-electronic-load-arduino/
Jakub designed and built a programmable electronic load for Arduino, the MightyWatt R3: MightyWatt R3 is a programmable electronic load. That means you can use it for testing batteries, power supplies, fuel cells, solar cells and other sources of electrical power. You can also make a programmable power supply from a fixed-voltage power supply and MightyWatt […]
MPPT solar charger

Lukas Fässler from Soldernerd has been working on revised version of his MPPT Solar charger project: Over the last few weeks I have been quite busy with my MPPT Solar Charger project. I’ve built up a first board and started writing firmware for it. Since the last version was not too different in terms of […]
Raspberry Pi LCD Touchscreen Rotation
https://www.electronics-lab.com/raspberry-pi-lcd-touchscreen-rotation/
In this video, Circuit Basics walks us through the steps to change the screen rotation on an LCD touchscreen for the Raspberry Pi. Since there are separate drivers for the display and the touchscreen sensors, we need to change the orientation of both. It’s pretty simple to do, but a couple packages need to be […]

Color sensor achieves high dynamic range with auto exposure
https://www.electronics-lab.com/color-sensor-achieves-high-dynamic-range-auto-exposure/
Massimo Gottardi@ edn.com writes: The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a subject are invariant over a range of light intensity. Color […]
