What does it take to build a geocaching box that can only be opened at sunset? A box, a button, an electronic lock, an electronic clock and a controller that ties everything together.

If you want to drive a 5×7 dot matrix display directly from your MCU, I have the right Arduino library for you. Flexible, easy to use, supporting low power operation, and a low memory footprint: DotMatrix5x7.

Running on batteries does not carry your Arduino project very far? Well, when you want to run an Arduino project on batteries, you have to spend some thoughts on minimizing power consumption. Here we will look at what you can do when you use an AVR MCU. Often you will be able to reduce the average current consumption to a few microamps!
