Sensor Kit Resource Hub
The Sensor Kit includes a huge variety of sensors and some supporting components for those devices, but it doesn't include everything you'll need to hook them up. Here are a few extra tools and components you may need to get started.
About half of the sensors in this kit are immediately breadboard-compatible, ready to plug in and connect to a development board. Here is what you'll need to get started with those components.
RedBoard Qwiic -- Every sensor in the kit is supported by a hookup tutorial, which includes an example Arduino circuit, and code written specifically for the popular development platform. The reliable RedBoard Qwiic can interface with any-and-every sensor in this kit. Just make sure to get the associated USB cable for your board.
Alternatively, any Arduino-compatible development platform -- be it a Arduino Uno, Pro or Pro Mini -- should be able to substitute. You'll just need Qwiic adapter or shield to connect the board to easily connect a Qwiic enabled sensor to the Arduino board if you decide to take advantage of the Qwiic connector. Again, make sure to get the associated USB cable for your board.
Breadboard -- These are a recurring player in every example circuit for every sensor in the kit. The breadboard holds your sensors, resistors, and other components, and even does some of the wiring for you.
Jumper Wires -- Like the breadboard, jumper wires are a part of every example circuit. These jumper wires act as an intermediary between breadboard and Arduino.
Once you move beyond some of the simple components in this kit, like photocells and flex sensors, you'll advance to the breakout boards. Breakout boards, like the sound detector ad RGB and gesture sensor (APDS-9960) are shipped without interface connectors, which means you'll need to whip out your soldering tools before connecting them to a development board.
Solder -- Large, small, leaded, lead-free...there are a few options to consider when you're picking out solder. Leaded solder is easier to use, and produces shinier joints, but has a certain stigma to it.
Headers or Wire -- You'll need to solder something to the breakout board. Whether that something is male headers, female headers, stranded wire, solid-core wire, or something else is completely up to you.
