Arduino Wifi Signal Strength Indicator
About the project
Using Arduino MKR WiFi I created a physical device to show WiFi signal via an LED that changes its light from Green to Red. It was fun to explore around the flat and see where we lack WiFi signal, but this could also be used as a way to quickly scan venues and coffee shops when setting
Items used in this project
While working on a project I needed 8 WiFi connected Arduinos. I implemented a trivial feature that allowed me to see when the Arduino has a good WiFi connectivity based on the built-in LED colour. The Arduino MKR WiFi provides dBm level, which is used to interpolate from green to red (hue value with HSV to RGB conversion).
This could be used as a way to quickly scan venues and coffee shops when setting up their WiFi networks to ensure good connectivity. The location of the router and extenders can be modified quickly to accommodate any potential dead zones.
