• Keep your surroundings safe and clean with building automation | Arduino Blog

  Whether it’s a home, an office, a school, a restaurant, or something else, it’s always important to keep your indoor environment safe, clean, and pleasant to be inside.

  It’s also a good idea to keep track of the air quality and conditions around you, not just for safety but also to ensure your systems are all working correctly and to avoid any wastage and inefficiencies.

  Accurately monitoring your buildings can seem like a big challenge, but it’s actually very achievable with the right tools, and in fact, doesn’t require a whole lot of technology and expertise to get started. In this article, we’ll look at why it’s so essential to monitor your buildings and how anyone can build their own systems for doing so.

• Carrier board supports Jetson Nano/NX modules

  SeeedStudio announced yesterday the A205E Carrier Board which is compatible with Jetson Nano/Xavier NX modules from NVIDIA. The A205 includes flexible peripherals such as dual GbE LAN ports, dual HDMI ports, one PCIe M.2 key-M for SSD storage, one M.2 Key for Wi-Fi/BLE, etc.

• How to Power Light Bulbs Using an Arduino With a Relay Module - Make Tech Easier

  Controlling tiny LEDs with an Arduino can be a fun project to kick off your journey learning DIY electronics. But do you know what’s even more fun? Powering light bulbs with a custom-built Arduino project: large, high-power, room-enlightening light bulbs!

  However, the Arduino can’t emit more than 5V from any of its pins, let alone enough to power a light bulb that needs 30 to 40 times the voltage for an LED. That’s why you’re supposed to use a relay module instead. Here’s how to do that with your Arduino.

• Rubber Stamping Your Way To Custom PCBs

  Many of us now outsource PCB production to board houses overseas, which offer high-quality boards with increasingly-impressive turnaround times. [Shri Hari Ram] still likes to brew up their own PCBs, though, and decided to try a new method to speed things up.
