Everything you need to prototype an IoT device and connect it to Google IoT Core. This kit comprises a Raspberry Pi3, GPIO breakout cable, breadboard, cables and wealth of sensors and actuators. Google Cloud IoT Core is a fully managed service to easily and securely connect, manage, and ingest data from globally dispersed devices.
An IR distance sensor, Trinket M0, NeoPixel strip, and AudioFX sound board plugged into powered speakers combine to make a booby trapped candy bowl. The CircuitPython program measures the distance of objects in front of the IR sensor, and changes the LED colors to match. Then, when you get too close, it screams bloody murder!!
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.
