555 box with LED display

thingiverse

A simple project to make mattstroud's 555 Timer / 8 Pin DIP Box into a fun electronics project. Just another blinkenlight one. You need to print out the 555 timer box and 4 simple LED mounts (for 5mm LEDs) - Instructions for how to do that are below. The circuit is based around an Arduino Nano that will flash the lights in a couple of different ways - **coming soon** **Remixed from:** I can't add them in the "normal way" but these are the things http://www.thingiverse.com/thing:1348469 http://www.thingiverse.com/thing:3554525 #Simple led mount. Designed for 3mm but it is good for 5mm LED, just to adjust the scale. (3mm to 5mm = 166%) #555 Timer / 8 Pin DIP Box This is based on the Snap-On 555 model, but modified to turn it into a storage box with a lid, so you can store all your precious bits and bobs in a lovely 555 Timer chip storage box. Enjoy! As requested by another user, there is also a plain lid incase people want to modify it to add custom chip numbers or custom text, or just want a plain topped lid. ** Instructions** * Print 1 Base and lid * Print 4 middle legs (with support) * Print 2 End Leg A * Print 2 End Leg B Print box in Black & legs in white/silver All files, the sketchup & fritzing files are attached so you know what parts to buy # Post Printing ## Box construction Legs should fit into the slots with a tight friction fit, although due to machine tolerances the tab in the legs may need a slight sand if tight or a dab of super glue if loose. ## Electronic parts * 4 x Red LED package * 1 x Arduino Nano (Rev3.0) * 4 x 220Ω Resistor * 1 x Toggle Switch * 1 x Battery block 9V PP3 ## Arduino sketch Upload the sketch via your software of choice. It only has a simple counter at the moment but that will change over time The plan is to have the following "modes" * counter - Counts from 0 to 15 in binary * "Chase" - Runs through lighting each LED in sequence * "Swish" - Runs "chase" but at the end it returns * "Random" - Lights the LEDs in a random order
