No, never had to do a claim lol. I don't take too many risk, doesnt pay off. So what I was thinking last night after posting is how am I able to write all the I/O's. I still don't understand how to send anything other than single letters or numbers. My equipment is all momentary switches. All the relays do is send the signal to directional valve to move the hydraulics. Since the equipment has three main boxes now i thought about taking advantage of the megas serial ports. That would be three master HC-05 and three slave HC-05 or 06 three separate binds.
