Introduction: Magic Bell (PushBullet+GMail)
Push notification (PushBullet + GMail) upon pressing wireless home bell.
Item used :-
- ESP8266 E-12
- Wireless Outdoor Doorbell
Step 1: Step 1 : Find a Tapping Point
Gut the electronic bell and find a suitable point to tap digital signal for the purpose of digitalRead(). In this case, i tapped from an led which turn on for approximately 3 seconds upon button press.
Using the voltmeter, measure the current to not exceed 20mA, in this case, the tapping point yield 5mA, within safe limit for GPIO digitalRead().
WARNING : High current could cause your board to fry. Double check the current, us resistor if needed (V = IR)
Step 2: Step 2 : Rig Up GPIO
Connect wire from the tapping point (in this case, LED ends) towards GPIO : GND and Pin5 (D1).
Step 3: Step 3 : Upload Code and TestItOut!
Copy the the modified Arduino codes & modify the details:-
Get your Device ID through PushBox and Access Token via PushBullet, follow detailed tutorial link below :-
Step 4: Step 4 : Solder It Out & Assemble It Back
Once everything worked out, replace all the crocodile clips and solder it well and assemble everything back! Viola!
