The Danger Shield mounts on top of your Arduino r Arduino Pro and equips it with a variety of fun and useful inputs and outputs. The Danger Shield has so much potential; we can't wait to see what you're able to do with it! The shield's features include:
- Three linear slide potentiometers connected to the Arduino's analog pins 0 through 2.
- Red and yellow LEDs connected to digital pins 5 and 6 - PWM pins - so you can easily vary their brightness.
- Three momentary push buttons connected up to the Arduino's digital pins 10 through 12. Those lines will go low when the buttons are pressed.
- A photocell and a temperature sensor, both with analog outputs, are connected to the analog pins 3 and 4, respectively.
- An 8-bit shift register set up to control a blue 7-segment LED.
- Two buzzers - one is used, as you'd expect, as a speaker, the other is connected to analog pin 5 and can be used as a knock sensor.
- Capacitive Touch pad - Using the CapSense library to sense touch.
This product comes as a kit of parts, which you'll have to solder into the included PCB. All parts are through-hole so it should go together relatively easily; but always check your component orientation before soldering!

Amazon Basics MERV 11 Filters: Solid Performance Without the Premium Price

Amazon Basics MERV 11 Filters: Solid Performance Without the Premium Price
I’ve been using these Amazon Basics 20x20x1 MERV 11 filters in my home HVAC system, and overall they’ve been a very dependable option for routine filter changes. I like buying them in a 6-pack because it takes the hassle out of remembering to reorder every couple of months, and the per-filter cost is noticeably lower than the big-name brands at the hardware store.
Installation is straightforward. The actual size fits my return slot properly with no bending or forcing, and airflow has remained strong. With MERV 11, these strike a nice balance for my setup — noticeably better dust and pollen capture than basic MERV 5 or 8 filters, but without putting obvious strain on the system. After about a month of use, the filters clearly show they’re doing their job, collecting a visible layer of dust and fine debris.
A few things to keep in mind. The cardboard frame isn’t as rigid as some premium filters, and they’re a bit thinner than brands like Filtrete. They’ve held up fine for me during normal use, but I wouldn’t try to stretch them much past the recommended replacement interval. Also, if you have an older or low-powered HVAC system, MERV 11 may be more filtration than you need — in that case, a lower MERV option might make more sense.
Bottom line: These Amazon Basics MERV 11 filters are a practical, budget-friendly choice that deliver solid filtration and good airflow for regular HVAC maintenance, as long as you stick to timely replacements and don’t expect premium-brand rigidity.

⭐️⭐️⭐️⭐️⭐️ I can breathe again — and my house says thank you 😂
These Amazon Basics MERV 11 air filters have been a game changer for my HVAC system. I installed them and immediately felt like my home went from “dust tornado aftermath” to “spa-day air vibes.” Whether it’s pollen, pet hair, or mystery dust bunnies lingering in the corners, these filters make the air feel noticeably cleaner and fresher.
Installation was about as easy as ripping plastic wrap off a new gadget — pop out the old filter, slide these in, and suddenly the air quality goes from “huh?” to “ahhh.” The electrostatic pleated design grabs everything from sneaky dust motes to pet dander like a champ, and I can actually tell when the AC kicks on that the air feels crisper — in a good way. 🌬️
Between the six count and the solid MERV rating, this was a smart purchase that keeps my HVAC happy and my allergies way more manageable. If you want clean air without the hassle, these filters are a fantastic value and really get the job done. Highly recommend!

Good, I think.
Pattern Name: 16x25x1, Style: Merv 11
Not my area of expertise but wanted something with a thicker filter and these seem to be doing well. They last 3+ months before discoloration is noticeable to the point you’d think it’s time to put in a new filter. The 6-pack price can’t be beat, truly. Easily installed and used, fits perfect to size and looks clean. Unknown relief on allergies so far since it’s been winter but I’m optimistic.

Better quality that name brand hardware store
Pattern Name: 20x20x1, Style: Merv 11
These are a great value for a multi-pack. They fit perfectly in the vent and you can definitely notice the difference in air quality. It’s much easier to just have a stack of these on hand so I can swap them out regularly without a trip to the store.
