Arduino counter

I needed a way to read pulses from our house and geothermal heat pumps electricity meters. Of course there are many pulse counters all ready, but I had make my own:) Just a simple sketch that counts pulses from pins 2 and 3 reports them on the usb serial when asked.

Main meter is read optically with a TSL257 and the geothermal pump meter is directly connect to the meter.

I use a python daemon to relay the data to MySql, code again in github https://github.com/mika-koivusaari/read_pulse_mysql
