Ardurino Logger

Posted on Feb 4, 2014

The switches and LEDs are here because they are mounted on the same front panel as the display. The `D` connetor, however, is at the rear. The two switches are momentary downwards, but latch upwards. I like to buy assortments cheaply, in this case single in-line resistor packs and DIP switches. This design makes a virtue of the common connection a

nd close matching of the resistor packs. It provides 8 ranges in 3V increments. Spare switch positions are used to optionally monitor the power supply voltages. The Adafruit logger shield has spare pads for extras and two uncommited LEDs. I wired in a pulse stretch circuit to detect responses from the SD, which would otherwise be too short to see. I used discretes to save space. I included code to turn on the DS1307 square wave, but have not used it.
