+  Clay trap transmitter
+
+  Hardware:
+  - Elechouse Voice Recognition Module V3
+      Arduino pin 2 -> VR module TX
+      Arduino pin 3 -> VR module RX
+      5V -> VCC
+      GND -> GND
+
+  - 433 MHz transmitter, like the FS1000A
+      Arduino pin 12 -> DATA
+      5V -> VCC
+      GND -> GND
+
+  Train the word "Pull" into records 0, 1, and 2 with the Elechouse
+  vr_sample_train example first, then upload this sketch.
