In this the second and final article of the Garage Light series I will be providing the receiver and associated circuitry and code to complete the project. When I started this project I didn't have a clear design and as a result got into a just one more feature mode and ended up with a nice design.
The Stopwatch project is an inexpensive bench Stopwatch/Timer, hardware/firmware solution that I have had on my long list of projects to do for some time. It has a simple interface; a 20x4 LCD display times and 4x4 keypad to configure the times. There are two main segments in the Stopwatch project; the clock source, an ATtiny2313 MCU that provides the clock pulses to the the Stopwatch segment, an ATMega328P that provides everything else.
As the old saying goes, "Necessity is the mother of invention" and in this case the need was a light in the garage that could be turned on for a period of time when motion is detected. We tried putting a couple of inexpensive motion sensitive, battery operated lights along the path to the recycle and garbage bins but they are so faint and you have to get so close to trigger them that it just didn't do the job.
3D Printer Filament, while not expensive per unit can add up when you have a number of rolls and protecting your investment against mositure is important. You could spend a lot of money on a prebuilt box but you can make one for a lot less, depending on options.
