It was a long and busy day today. I expected it to slow down, but work poured in right at quitting time and I am just finishing up what was possible to finish. The good news is that the relays to control the LED’s for the bean sorter project arrived today. They are small, cheap and should be perfect for this project, but not as the strobe control I/O’s we need. They are mechanical relays that can switch at a maximum rate of 10ms to active and 5ms to inactive. That is way to slow for what we want to do. The good news about the bad news though is that I thought I was only getting one board, but I got two and I will be able to use them to do a lot of the development work while I wait for some faster solid state switches AND I will be able to use them in the product to control the indicator lights that show machine status.
