39 | Beginning with ArduinoBuilding a night light: using a photocell and LEDOverviewThis activity combines the use of a photocell (light-dependent resistor) as an input to the Intel®Galileo Gen 2 board with an LED as an output, to operate when in dark and turn off when inlight (a night light). Programming code is minimal and operation can easily be calibrated, usinga 10K potentiometer, to any room of the house. Some basic paper cutting and manipulation isrequired to enhance the lighting effect.Materials»»1 x Intel® Galileo Gen 2 board»»1 x 12V Power supply»»1 x Micro USB lead»»1 x Breadboard»»4 x Jumper leads (M-F)»»1 x Jumper lead (M-M)»»1 x Photocell»»1 x 5mm red LED»»100 Ω ResistorOther items required»»1 x A4 sheet of white paper»»Masking tape
A TEACHER’S GUIDE TO THE INTEL® GALILEO | 40Hardware construction1. To make the night light diffuser fold an A4 piece of paper into A5 size, fold again and cutstrips along the fold.2. Roll paper long ways and tape into a tubular shape and use masking tape to hold endstogether.WiringRefer to circuit diagram for wiring of individual components:1. Connect positive lead of LED Pin 11 and twist a resistor around the negative lead,connecting the other end of the resistor to GND.
