Arduino lockbox escape room puzzle
thingiverse
Using a small hard case off ebay : https://www.ebay.com.au/itm/363404275140?ViewItem=&item=363404275140 I designed the parts to convert it into a compartment with an arduino keypad and lights. Arduino code then requires correct code before beeping and flashing lights, then activating a solenoid to lift the lid. Parts needed: Arduino UNO green / red LED's buzzer HD keypad LCD screen 12v solenoid (push type) small magnet (used old name badge) 11.1V battery (used old LIPO battery but could run off other system) MOSFET driver module (for 12v relay) misc. plugs/wires
