I seem to have got the logging function working. The one issue is with the pulse LED on PIN4 of the board. It should pulse with each pulse of the electricity meter. However I can’t get this to work. The pulse sometimes works but more often than not, there is no pulse from the LED. I’ve tried adjusting the pulse delay but with no effect.
Anyone offer any guidance on getting the pulse LED to show a visible pulse. The data appears to be written correctly to the SD card which suggests the sensor is detecting the meter pulses but the indication LED is not pulsing. Not essential but a useful visual feedback to check that the data is being recorded correctly.
Thanks for any help.
