+# Oscilloscope
+oscilloscope with customizable trigger and polling rate.
+
+## Setup
+1. Open the script in the editor
+2. Set the side wich the redstone signal will be read from
+3. Set the interval at which the signal will be polled (setting it below 0.05 will not give more resolution as this is the tickspeed)
+4. (Optional) Customize the trigger function to trigger when you want it to (see examples below).
+
+### Example triggers
+Trigger when receiving full signal:
+```lua
+local trigger = function(previous, current)
+    return current == 15
+end
+```
+
+Triggers when the difference in the measured signals is more than positive 7:
+```lua
+local trigger = function(previous, current)
+    return (current - previous) > 7
+end
+```
