TfCD Night Lamp by D. Park and L. Strauss

Are you tired of switching on your lights manually over and over again? Here`s a step by step instructable on how you can make your very own customized automated lighting switch. In all seriousness, this prototype was built in the scope of the course TfCD at the TU Delft.

For a light controlled night lamp you will need the following components and a computer/laptop: 10K Ohm Resistor, 330 Ohm Resistor, LDR (Photoresistor Sensor), LED (red), Arduino microchip controller, 6 Wires, Breadboard, USB Power Cord

Step 1: Power Breadboard

Use the 5V pin as power source. Make sure that it is connected to a positive input of the breadboard.

Step 2: Connect the LDR

Then assemble the LDR and connect it to the positive power rail of the breadboard. Note: Plug the new wire (green) into the same breadboard row as one of the LDR`s pins.

Step 3: Add the Resistor

In this step you have to add the 10K Ohm resistor, sharing the same row with the LDR´s second pin. The resistor should then be connected to the ground (blue rail).

Step 4: Complete First Circuit

Take the fourth wire (orange) and plug it into "A0", an analog input pin of your Arduino. Make sure to connect the LDR with this wire, using the same row as the resistor.
