Its uses a building block approach to electronics, which is great for users with little to
no experience of electronic circuits. The Grove system consists of a base shield and some
modular blocks; in our instance, the Photon kit comes supplied with the following parts:

Grove Shield for Photon

Grove—Button

Grove—Buzzer

Grove—Rotary Angle Sensor

Grove—Temperature Sensor
Grove—Light Sensor

Grove—Chainable RGB (red, green, blue) light-emitting diode (LED)

Grove—Three-Axis Digital Accelerometer (±1.5 g)

Grove—Four-Digit Display
Grove—Vibration Motor

User’s Manual

In this experiment using IFTTT, every time someone mentions you on Twitter, the

buzzer and vibration motor will go off for one second, alerting you to the tweet. To get
started, go ahead and insert the Photon board into the Grove Photon shield as shown in
Figure 8.11, making sure the orientation is correct.

Figure 8.11 Photon base shield.

For this experiment we are going to be using the Grove buzzer and the Grove vibration
motor. Connect the Grove vibration motor to connector A4 on the Particle shield, and
connect the buzzer to the I2C_2 port on the shield. The hardware for this experiment can
be found in Table 8.2.
