Amy Ciavolino’s friends were stuck outside of her apartment waiting to be let in to the party. They repeatedly pressed Amy’s apartment buzzer with no luck. The buzzer was too quiet, and Amy’s party was too loud. Throughout the night, the cycle repeated: Amy’s friends pressed the buzzer, waited in vain, finally called Amy, and Amy would come to the rescue, only to be interrupted moments later.
To fix her buzzkill of a buzzer, Amy and her friends put their heads together and built a Twilio powered solution that triggers Amy’s apartment buzzer by texting a password to a Twilio number.
Below is Amy’s tutorial originally posted on GitHub here.
How To Set Up A Buzzer Bot
Chances are if you have a Raspberry pi, and you’ve done anything at all with it, you’ve turned on an LED. This project is almost as simple as that. The software requires a some set up, but hardware-wise, if you can turn on a LED, you can do this.
- A raspberry pi with Node js installed
- A domain from freedns
- A twilio account with a phone number
- An optocoupler (I used this one)
- Some resistors
- An LED
