Fun arduino project with esp8266

(Fun arduino project, esp8266, with Push Notification.)

Brief description:

The Slave esp8266 when triggered sends message to arduino Nano/Master 8266 to close solenoid & send push notification. Setup the push notification via [login to view URL]

Detailed description:

Slave Hardware:

1. esp8266

2. 10k pull down resistor

3. 1 led.

4. Sensor detection wire. Two wires. One side to grd., other wire to resistor 8266 pin.

Slave esp8266 Function: (one way communication to master), Lives in sleep mode unless triggered,

1. When sensor wire placed in liquid, event is triggered.

a). Flash led on slave 5 times- led off.

b). Transmit message 3x times to master 8266/nano/solenoid- (close solenoid), then back to sleep.

c). When the sensor wire is removed from the liquid, sensor trigger resets. When triggered again by liquid detection, New message to Nano to close solenoid is transmitted.

d). Included in the payload message to master8266, Sensor identification: (H20 Sensor 1x),

Master esp8266 Hardware:

1. 1 Arduino nano

2. 1 red led, 1 green led

3. Reset button

4. 1 H-bridge

5. 1 solenoid, 30ms electric pulse open/ 30ms electric pulse close

Master 8266/nano: (Response)

1). When nano powers up. Red led flashs 3 times. All led's off.

2). When message received from slave8266 - close solenoid.

a). Red led turns on

b). Send push notification, "Alert...Solenoid closed" "Sensor 1x" (Date/time), via ([login to view URL])

c). Reset button on nano can open solenoid, app can open the solenoid. When solenoid opened led turns green.
