hi, when compiling my program, i get this problem. cpp.11: undefined reference to 'setup'
and cpp.14: undefined reference to 'loop'.. what should i do sir? please help.

but i am using a signal and a delay for it. if i will use interrupt, it will pause the other process just to accommodate the new one. is it right? i have to arranged in my program what will be the first and what will be the second?

Hi, I bought 8 solid state relays and 1 mcu, if i will be pinning Logic input of those relays to my arduino, can i use those relays in different instances? let's say for example, i have a coin acceptor to trigger relay 1. if relay 1 is already working with a time of 5 minutes, Can i still use the other relays without interrupting the process of relay 1? kindly help me. I am making a vendo charging station with the use of 1 mCu. is it simultaneously possible or sequentially possible. can i use those relays at different time or one after the other?

so it means i cannot have two processes at the same time? it is sequentially possible but it comes in sequence right?

Hi, I'm Edward and I am in the middle of my thesis. can some here please help me to program my Arduino 2560? Is it possible to control 6 relays at different instances? I mean can arduino do multitasking without interrupting the first process? Please Help.
