If you do not know how to use a breadboard, see the breadboard tutorial in the Bibliography.Innovative Galaxy Projector. Figure 2 shows the circuit on a breadboard. You can use this diagram if you plan to solder the circuit yourself on a protoboard (you will need to decide how to arrange the components). Figure 1 shows the connections directly between the leads of the different circuit components. To wire the circuit, see the diagrams in Figures 1 and 2. A jumper wire to make a required connection on the breadboard.A transistor, which acts as an electronic control valve to turn the LED on and off.Its resistance changes in response to ambient light. A photoresistor, also called a light-dependent resistor (LDR) or photocell.A potentiometer, which allows you to set the light threshold for the circuit to turn on.A current-limiting resistor to prevent the LED from burning out.Super bright LEDs in a variety of colors.A 2xAA battery pack to power the circuit.A mini breadboard for building the circuit.The parts to build the circuit are available in the DIY Night-Light Kit. If you need some help getting started and learning how to build an LED night-light circuit, first watch this video for an overview and explanation of how the circuit works: Can you make a functional, aesthetically pleasing case or enclosure for your circuit? You could make a case using craft materials, wood, or even a 3D printer if you have access to one. Most people probably do not want an ugly, bare circuit board sitting around their house. You will need to build the circuit, but you will also need to think about the physical design of the product. In this fun engineering project, you will design and build your own night-light. Night-lights can be found in many homes you might even have one in your bedroom! Using a night-light is a great way to avoid stubbing your toe on furniture during a midnight trip to the bathroom. If you want a Project Idea with full instructions, please pick one without an asterisk (*) at the end of the title.
