• Embedded internet connectivity
• Easy to program
• Secure cloud connection
Device Cost Cloud Providers “Dev Environment”
Raspberry PI Zero W (+ SD Card) $17.00 All Okay
ESP8266 (Dev Board) $10.00 All Poor
Particle Photon (Dev Board) $19.00 Particle Device Cloud Excellent

12. What is

13. Devices
WIFI Cellular
Photon P1 Electron E Series
120Mhz ARM Processor
Broadcom WiFi Chip
120Mhz ARM Processor
2G / 3G GSM cellular radio

14. Cloud Services
Device running
Particle’s “Device OS”
Particle’s
“Device Cloud”
Your
Application

15. Particle.connect()
Particle’s
“Device Cloud”
NAT /
Firewall
Constrained Action Protocol (CoAP),
RSA + AES encryption,
over TCP

16. Particle.variable()
int analogvalue = 0
void setup() {
Particle.variable("analogvalue", analogvalue);
}
void loop() {
analogvalue = analogRead(A0);
}
GET /v1/devices/{DEVICE_ID}/analogvalue

17. Particle.function()
void setup() {
Particle.function("brew", brewCoffee);
}
int brewCoffee(String command) {
if (command == "coffee") {
return 1;
} else return -1;
}
POST /v1/devices/{DEVICE_ID}/{FUNCTION}
curl https://api.particle.io/v1/devices/0123456789abcdef/brew
-d access_token=123412341234
-d "args=coffee"

18. Particle.publish()
double v2 = 0;
void setup() {
}
void loop() {
v2 = v2 + 1;
Particle.publish("Value Changed", String(v2), PRIVATE);
delay(2000);
}

19. Particle.subscribe()
int i = 0;
void myHandler(const char *event, const char *data
) {
i++;
Serial.print(i);
Serial.print(event);
Serial.print(", data: ");
if (data)
Serial.println(data);
else
Serial.println("NULL");
}
void setup() {
Particle.subscribe("temperature", myHandler);
}
