Breathe easy - we finally have an I2C VOC/eCO2 sensor in the Adafruit shop! Add air quality monitoring to your project and with an Adafruit CCS811 Air Quality Sensor Breakout. This sensor from AMS is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and is intended for indoor air quality monitoring.
I2C is incredibly popular because it uses only 2 wires, and like we said, multiple devices can share those wires, making it a great way to connect tons of sensors, drivers, expanders, without using all the microcontroller pins. The only bad news about I2C is that each I2C device must have a unique address - and the addresses only range from 0 to 127 (aka 0 to 0x7F hex). Since we deal with so many I2C devices we thought it would be handy to have a table with all the most common sensors and modules we encounter, and their I2C address!
Vintage radios can be beautiful, but many are beyond repair. Here's a guide to repurposing it as an eerie playback device that uses the original tuner dial, power knob, and speaker and grafts on a Feather ESP8266 Huzzah with Music Maker MP3 FeatherWing that can play creepy sound effects, and trigger a specific song when intrepid guests tune the dial to a specific frequency. Muhuwahahahahahaha!
This project turns a toy hammer into a magic wand that produces different sound and light effects depending on the spell cast based on simple gesture recognition. The amount of components in this project combined with the small room requites a bit of cramfu to get all the parts to fit. The compact nature of this project and the number of components means it's a best for a somewhat experienced maker.
Interpretting datasheets is fraught with peril in the best of circumstances. Even chips from the same vendor can use varying terminology and units, often in an attempt to hide short-comings in individual devices. Trying to compare chips across vendors adds another layer of complication. We'll help you decipher the key terms around gyroscopes in this learning guide.
For many microcontrollers, adding audio input is easy with one of our analog microphone breakouts. But as you get to bigger and better microcontrollers and microcomputers, you'll find that you don't always have an analog input, or maybe you want to avoid the noise that can seep in with an analog mic system. Once you get past 8-bit micros, you will often find an I2S peripheral, that can take digital audio data in! That's where this I2S Microphone Breakout comes in.
The NeoPix Arcade Kit is a 1D arcade game system to encourage young programmers to code. The NeoPix Arcade Kit comes with a preprogrammed Circuit Playground that includes our 1D Pong Game to immediately start exploring basic game programming concepts on the Circuit Playground. The Circuit Playground Board has a host of sensors to create a variety of handheld electronic gaming projects.
Add motion, direction and orientation sensing to your Arduino project with this all-in-one 9-DOF sensor. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The third is a 3-axis gyroscope that can measure spin and twist. By combining this data you can REALLY orient yourself.
