In this lesson, we will connect an ultrasonic sensor to the Oak. An ultrasonic sensor allows you to detect
| Part | Quantity | Identification |
|---|---|---|
| Oak with soldered headers | 1 | |
| Breadboard | 1 | |
| Ultrasonic Sensor | 1 | US-100 Y401 |
| Jumper wires | 6 |
Note: The HC-SR04 sensor is NOT being used in this tutorial as it uses 5v. Instead a US-100 sensor, which operates with 3.3v is used.
Particle.publish will be used to send the sensor data to the cloud. To view the data, you will need a free Particle account, which you can get here if you done have one already: https://build.particle.io/signup.
