Getting into the building for some Nola tech meetups can be difficult after 6pm. Currently, folks just ping on Slack and hope someone sees the message to let them in. It would be great if there was a bright, physical signal for all to see when someone is waiting outside.
The hack is called Ding Dong because we basically just want to make a (visual) doorbell 🛎️.
Our goal is use an Arduino compatible microcontroller (NodeMCU 1.0 - ESP-12E Module) and Arduino Cloud to create a remote controlled light switch. We've broken down this process into six milestones.
-
PREREQUISITES - Terms and concepts
-
Milestone 1 - 'Hello world' for the MCU board
-
Milestone 2 - Create a virtual button that controls a variable
-
Milestone 3 - Use the virtual button to toggle an LED
-
Milestone 4 - Add a relay to your circuit
-
Milestone 5 - Add a light source to your circuit
-
Milestone 6 - Add whatever you want
