We already have many guides with TM1637 LED display module and Arduino. Is not it risky to use led display unprotected? We do gave good wooden stand for 3V DC motor. Here is how to build DIY basic stand for TM1637 7 segment LED display module with cardboard. You need just a cardboard, a pencil, a ruler, a paper knife, gum, 4 male to female jumper wires to build it. It is easy, cheap, fast to build and will protect the unit in primitive way.
How to Build DIY Basic Stand For TM1637 7 Segment LED Display Module
Cut a cardboard in proper size, fold it to make it like a box. Mark the window with a pencil which needs to cut out. Cut it out with a paper knife and push the TM1637’s display in a way that the cardboard holds. Attach the male to female jumper’s female end to the TM1637’s display unit. Use gum to make the folded cardboard a real two end open box. There is no difficult craftsmanship :
How to Build Advanced Stand For TM1637 7 Segment LED Display Module
TM1637 has 4 holes on PCB, they are for adding female threaded PCB standoffs. If you make the stand with wood, you could fix the TM1637 on one wooden board with PCB standoffs which is back of the wooden stand. The front wooden board will be of same dimension that of the wooden board the TM1637 unit will seat but will have a cut out window for the display. Complete the wooden box with wooden boards on four sides. Add an acrylic board at the front. You need to drill to give the jumper wires a way.
There are Made in China LED clocks with the above described design :
We have circuit diagram and code of TM1637 Arduino clock, list of basic electronic components to build Arduino TM1637 clock, various animation effects like scrolling texts, circuit diagram and code of temperature sensor with the display. You can create permanent or temporary “production grade” thing combining those projects.
