+# MultiChanTicker
+
+The idea of this ticker is to multiply the output channels. The original Golang `time.Ticker` provides only a single output channel, so the signal can only be received by a single other class. This ticker allows to add multiple channels which get all notified about the time tick.
+
+```golang
+type MultiChanTicker interface {
+	Init(duration time.Duration)
+	AddChannel(chan time.Time)
+}
+```
+
+The MultiChanTicker is created similarly to the common `time.Ticker`:
+
+```golang
+NewTicker(duration time.Duration) MultiChanTicker
+```
+
+Afterwards, you can add channels:
+
+```golang
+t := MultiChanTicker(duration)
+c1 := make(chan time.Time)
+c2 := make(chan time.Time)
+t.AddChannel(c1)
+t.AddChannel(c2)
+
+for {
+    select {
+    case t1 :<- c1:
+        log.Print(t1)
+    case t2 :<- c2:
+        log.Print(t2)
+    }
+}
+```
+
+The result should be the same `time.Time` output in both channels, notified "simultaneously".
