In December 2020, the Australian Government made mandatory safety and information standards for button/coin batteries and consumer goods that contain button/coin batteries (the standards). The standards included an 18 month transition period and became mandatory from 22 June 2022. From 22 June 2022 manufacturers, importers, wholesalers and retailers of button/coin batteries or consumer goods that contain button/coin batteries supplied to Australia, must comply with the applicable Australian mandatory safety and information standards. Supplying or selling non-compliant products to consumers in Australia is illegal. The four mandatory standards are as follows:

===== Summary =====
Lightup Box is a short - 10-15 minute - community engagement activity designed to accompany basic explanation of electronics like the Electronics 101. 

==== Materials ====

These materials are per participant if not specified otherwise.
  - 1 x CR2032 Battery (See warning above) 
  - 4 x LED (in one colour) 
  - 3d printed box  (see below)
  - Mini breadboard. 
  - 2x resistor ( 75 Ohms)
  - jumper wires 


 ==== Tools ====
Multimeter
Hot Glue gun


 ===== Instructions =====



 ==== Step Zero: Prep ====
cut off **B** end of usb cable and terminate positive (red) and ground (black) conductors with a male jumper cable lead as pictured below. (secure other conductors against short circuits with heat shrink).  one for each participant. 
  

 ==== Step One: ====
Use [[https://ledcalculator.net|LED Calculator]] to get a circuit diagram

{{workshops:prototypes:screenshot_2024-11-08_at_3.06.53 pm.png}} 


 ==== Step Two: ====
Review how a multimeter and breadboard works. Familiarise /Test LEDs with CR2032 Battery 

use the multimeter on the Continuity setting to demo how the bread boards work 

{{:meter.png?400}}

Select the continuety setting by 
•	selecting Ohm on the Dial  {{:ohm.jpg?20}}
•	And use the blue button in the image above to select the continuity setting {{:continuity.png?20}}

{{workshops:prototypes:how_abreadboard_works_.png}}

 ==== Step Three:  ====
Work out how you are going to use the bread board to connect your circuit. 

Here's how i did it 

{{workshops:prototypes:screenshot_2024-11-08_at_3.32.19 pm.png}}

 ==== Step Four:  ====
Assemble you circuit on you bread board and test it with the power source.  

 ==== Step Five: ====
if it works hot glue you're components in place and install the circuit into you 3d printed box 

Extension Activity



 ==== Activity Extensions ====
Work out how you could use [[https://www.lithophanemaker.com/Lithophane%20Light%20Box.html|lithophanemaker]] to add an image to the 3D printed box
