Its JavaScript interpreter gives you instant feedback so that you can experiment and develop whatever your level of experience. Even if you can’t […]
Bubble display shield for Adafruit Trinket
https://www.electronics-lab.com/bubble-display-shield-for-adafruit-trinket/
davedarko created this Adafruit Trinket Pro shield for the HP QDSP-6064 bubble display. The design files and source code are hosted on GitHub. An additional temperature sensor in the form of the LM75 can be added to this bubble display shield. The atmega32p is capable of driving up to 40mA per pin, so with the […]
How to Implement Embedded Ethernet
https://www.electronics-lab.com/how-to-implement-embedded-ethernet/
Maurizio @ dev.emcelettronica.com has tipped us with his latest article on how to implement embedded Ethernet on any mcu. The article shows the basic principle of Ethernet implementation. Usually We need embedded systems inside devices, particularly the so-called intelligent devices, to communicate with a command/control/administrative center. Typical such situations could be a remote security camera […]
Geiger–Müller counter that works with Arduino
https://www.electronics-lab.com/geiger-muller-counter-that-works-with-arduino/
Bob @ robertgawron.blogspot.com has posted a Geiger-Muller project that can be used with Arduino or any other microcontroller board. The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of […]
