Distance Sensitive Alerting Machine / Price List

This instructable will teach you how to create a distance sensing machine that alerts you at different stages in terms of your distance from the sensor. These alerting tools include an RGB LED that illuminates the three traffic light colors as you get closer and closer, a seven segment display that displays your distance from the sensor, and a motor that is always running to let you know that the machine is on. This build also includes a normal red LED that is always on above the seven segment display to let you know that the power is on.”
