This is a way to automate the mobile games by using clever electronic circuitry placed on top of your phone.

The microcontroller senses the inputs from a sensor that is used to detect what's on the screen, analyses the data using a logic that has been programmed into it and sends appropriate commands to the touch circuitry.
Refer to the Electronics chapter in the book to learn in detail about how the sensing and touching circuits work.
Advantages of this approach
- It's very fast unlike the previous approach. This speed is very important for solving many games.
Disadvantages of this approach
- External conditions such an ambient light might affect the working of the circuits.
- Setting up the touch part of the circuit takes some time.
- It's difficult to implement complex algorithms on Arduino.
- Circuit required to simulate swipe is complicated and involves mechanical parts.
Games which can be solved using this method
'Piano Tiles' and 'Ready Steady Bang' can be solved using this method because in these we just need to detect a intensity change on a small part of the screen using sensors and then simulate touch using electronic circuits.
