(start at minute 14:31) • UPDATE 2/18/2020: • --- At minute 7:20, I revisited this code based on correspondence with Argent Data Systems and a review of libraries prepared for their hardware. If I set the debounce constant to 15, and then multiply it by 1000 on line 56 of the code, this eliminates the problematic bounce demonstrated at 7:35. With this edit, the code does execute successfully with the bounce filtered out. In response, I updated the sketch weatherStationMod3_g available on http://www.modestmaker.com/arduino/pa... under Chapter 9 with these edits. • --- The successful code modification and tests suggests I can use a reed switch in a tipping bucket rain gage coupled with an Arduino without needing to incorporate an RC circuit and a Schmidt trigger, or replacing the reed switch with a Hall Effect Sensor. However, these alternatives are mechanically and electrically sound while simplifying the code. • --- At minute 8:29, I incorrectly stated: Interrupts.... generally should not be used with timers that take more than a microsecond to execute . That is incorrect - I should have stated millisecond rather than microsecond . • -- At minute 8:55, I incorrectly state there is a delay in my interrupt function. This is incorrect - there is no delay in the interrupt function shared in my code. • In this video, I reverse engineer how tipping bucket rain gages work, and then demonstrate how to integrate an Arduino for counting tips, which can then be translated to rainfall depth. I then demonstrate software and hardware remedies for filtering out bounce noise associated with the reed switch used in these instruments.
