 These resistors are soldered to the Arduino Mega 2560 Channel 46.
+**Additional Solution**: In Arduino code, the I2C handler is looking for a fixed number of bytes on the inbound message. If it doesn't receive that many bytes, misbehaving code will just print an error message and go on. Was able to get the code to work by calling ''Wire.read()'' to read off the errored number of bytes.
+With code like this:
+<code c>
+    // Read off all of the bytes
+    for (i = 0; i < numBytes; i++) {
+      byteBuffer[0] = Wire.read();
+    }
