Moonlighting Lamp

Moonlighting Lamp is a glorified nightlight that changes brightness based on proximity. Most nightlights use a motion sensor to detect someone's presence and abruptly turn on. The Moonlighting Lamp uses a proximity sensor to detect someone's presence and calmly illuminates as they approach. The light is only as bright as you need it.

Step 2: Assemble the Circuit

Start by preparing the ultrasonic rangefinder. Solder the 7-pin female header pins to the through-holes. We'll only be using three of the pins: GND, +5, AN. Wire the rangefinder, leaving enough slack for the sensor to sit on top of the lamp shade. Continue populating the breadboard according to the below pictorial and schematic diagrams.

Step 3: Program the Arduino

Copy and paste the Arduino program from GitHub into your Arduino IDE. Run Verify and Upload. If you don't see a lot happening, try covering the LDR sensor. The program is configured to only power the rangefinder in low-light conditions. This value can be tweaked under // enable distance sensor only if day.

Step 4: Assemble the Lamp

Place the lamp shade over your circuit and thread the rangefinder through thee top. If necessary, use the plastic container to house and center your circuit.

Step 5: Enjoy

Plug in your Arduino and enjoy...at night.
