Hello all. So, I have learned more off this forum than I ever imagined (I now have a fully functional temperature/humidity controller, which I can send via FM RF about 100 metres using serin2/serout2, switch on humidifiers, switch on de-humidifiers, switch on heaters, coolers)...so now I need to know how to make a string of several different variables, I.E. out= A joined with B and joined with C. Am I making sense?
