+
+##### About the game:
+Timberman is an oldschool arcade style casual game. You have to put on your checkered shirt, pull up your sleeves, pick up the sharpened ax and ... grow a beard. In a moment there will be splinters flying and knocks off ax will bear echoed through the forest. Show how quick and how efficiently you can cut down a hundred-meter tall pine tree. But be careful, work of a lumberjack is tough and it's not hard for the accident at work. In addition, time is chasing you in every step not giving even a moment to rest. 
+
+##### Difficulty Level : 
+Easy
+
+##### Overview
+As soon as the timber branch appears above the timberman, the voltage output from the pin where the LDR is connected decreases. Whenever a drop in voltage is detected, the output pin is set to LOW and thus the Relay output is connected to ground which is equivalent to a 'Touch' on the other side of the side bearing lumberjack. In the absence of branch overhead, repeated touch is simulated on the same side of lumberjack.
+
+##### Requirements
+* An Android Device with the 'Timberman’' game installed on it. (Turn on the Developer options for better visualization)
+* Arduino, Breadboard, 22k Resistor X 2, LDR, Relay X 2, Connecting wires, two conducting metal coin
+* Computer to program Arduino

+##### Tutorial
+Here's the step-wise tutorial to automate the game.
+
+**Step 1: Sensor placement**
+
+The LDR is fixed on the screen exactly above the head of the wood-cutter on the left side. When the branch appears, the intensity of the light from the screen being detected by the LDR decreases.
+
+**Step 2: Touch simulation**
+
+The coin is placed on the screen and the output from the relay is connected to it. When the relay output is grounded, it simulates a touch on the screen and when it is open circuited, it withdraws the touch.
+
+**Step 3: Arduino code**
+
+Initially, set the output pins
+```
+int left=4,right=5;  
+```
+```
+void loop() {
+   int sv = analogRead(A0);  //read the input on analog pin A0
+   Serial.println(sv);  //print out the value you read:
+  //When a branch is encountered, right tap two times (until then, the branch      disappears)   
+   if(sv<750)  //threshold value=750
+   {
+       digitalWrite(right, HIGH);  //simulate no touch
+       delay(700); 
+       digitalWrite(right, LOW);   //simulate touch
+       delay(700);
+       digitalWrite(right, HIGH);   //simulate no touch
+       delay(700); 
+       digitalWrite(right, LOW);   //simulate touch
+       delay(700);
+   }
+   else   //otherwise keep tapping left
+   {
+       digitalWrite(left, HIGH); // simulate no touch
+       delay(300); 
+       digitalWrite(left, LOW); // simulate touch
+       delay(300);
+   }
+   // delay(100);        // delay in between reads for stability
+}
+
+##### Conclusions
+
+This way, the the circuit plays the game for us. Because the reaction time of the circuit is very fast, it can make highscores!
