Hello guys
im stuck in project, i started using this forum post
viewtopic.php?f=32&t=127870&sid=457f2cd ... 26#p958526
But this example works fine when the coin module pulses at 5v.
the one i have pulses at 0.7v. My electronics are very basic.
Can this be read or sensed by the Raspberry pi GPIO? i need to count ms pulses to identify the coin value.
please advice, thanks
