Light-Level Logger
The goal of this project is to build a simple tool for logging light intensity against time. The idea is that when planning your garden planting, you can have a reasonable idea of how much sunlight an area receives. Ideally, you would want to compare readings in different locations over the same 17-hour period, so you would need more than one of the devices.
The figure 17 hours is not completely arbitrary. It will cover the daylight hours in most parts of the world, and you will be able to store one reading per minute into the electrically erasable programmable read-only memory (EEPROM) for that period without having ...
