# Physical Inputs

Here are references for how to connect and code each physical input in your SparkFun Photon kit:

* [Push Buttons](/code-internet-of-things/references/physical-inputs/push-buttons.md)
* [Trimpot Dial](/code-internet-of-things/references/physical-inputs/trimpot-dial.md)
* [Motion Sensor](/code-internet-of-things/references/physical-inputs/motion-sensor.md)
* [Magnetic Switch](/code-internet-of-things/references/physical-inputs/magnetic-switch.md)
* [Light Sensor](/code-internet-of-things/references/physical-inputs/light-sensor.md)
* [Temperature Sensor](/code-internet-of-things/references/physical-inputs/temperature-sensor.md)
* [Soil Moisture Sensor](/code-internet-of-things/references/physical-inputs/soil-moisture-sensor.md)
* [Accelerometer](/code-internet-of-things/references/physical-inputs/accelerometer.md)
* [Ultrasonic Sensor](/code-internet-of-things/references/physical-inputs/ultrasonic-sensor.md) (not standard part of SparkFun Photon kit, but your teacher may have added it)

**OTHER SENSORS:**  There are references for other sensors such as [RFID Reader](https://docs.idew.org/internet-of-things-project/references-for-wiring-and-coding/rfid-reader), [Fingerprint Scanner](https://docs.idew.org/internet-of-things-project/references-for-wiring-and-coding/fingerprint-scanner), and [GPS Receiver](https://docs.idew.org/internet-of-things-project/references-for-wiring-and-coding/gps-receiver) in the **old** project guidebook. These references will eventually be transferred into this new code guidebook.
