+How to use the timer:
+Send a number representing a time in seconds, from 0.5 to 3600. When the time expires, the timer will send "done" back on the same channel. If the loop feature is enabled (use the commands "loop_on" and "loop_off" to set this) the timer will automatically be set for the same time again each time it expires.

 How to use the junction box:
 These are just plain digilines conductors (like digimese) but can skip over one node to another junction box or certain other nodes.
 As in, [digiline][junction box][dirt][junction box][digiline] will work to transmit signals "through" the dirt.
