LED control over Google Assistant

Step 1: Hardware Setup

Connect your LED to BOLT Wi-Fi module.

Plug the longer end of the LED to Pin 0 of the BOLT module and the shorter end of the LED to the Ground(Gnd) Pin of the BOLT module.You can see the connection in the below.

Step 2: Set your BOLT device

Now, power ON your BOLT Wi-Fi module to the power source and check that it is cinnect to the BOLT cloud and internet (make sure that the blue & green indicators are ON).

Step 3: Creating GPIO control

The structure of the control command is:

• To turn ON the LED:

https://cloud.boltiot.com/remote/API_KEY/digitalWrite?pin=PIN_NUMBER&state=HIGH&deviceName=DEVICE_ID

• To turn OFF the LED:

https://cloud.boltiot.com/remote/API_KEY/digitalWrite?pin=PIN_NUMBER&state=LOW&deviceName=DEVICE_ID

where,

• API_KEY: You can get it from API tab on cloud dashboard.
• PIN_NUMBER: Pin to which you have connected the LED. Values can be either 0, 1, 2, 3 or 4
• HIGH: This value indicates if you want to turn on the LED. HIGH will turn it on.
• LOW: This value indicates if you want to turn off the LED. LOW will turn it off.
• DEVICE_ID: The id of your device. You can get it from cloud dashboard.

*note: You can get your API key and Device ID from the BOLT cloud.
