Hi I am hoping for advice re the following query. Some background to my query follows:
I am building a planter monitor that will count seed drop through a John Deere 8 row planter. The drop tubes have one photo electric sensor per planter row and I have a working sketch to monitor 1 row.
I need to scale this up to monitor 8 rows simultaneously (assuming this is possible) and I want to wirelessly (bluetooth) the seed counts to an Android tablet mounted in the tractor.
The signal processing/conditioning from the row sensors is relatively straight forward. The maximum pulse count per row is 200 pulses per second.
My query is
- Can all of the digital i/o pins be used to undertake pulse counts simultaneously?
- Which of the Arduino family of boards would be best suited to this task?
