In this tutorial, I'll show you how to use a wireless PlayStation 2 (PS2) joystick to pilot a robotic tank. An Arduino Uno board was used at the core of this project. It receives commands from the wireless controller and sets the speed of the motors. Other development boards might also be used (NodeMCU, Firebeetle, etc.), and the principles presented in this tutorial can be applied on other models of robots and gadgets.
The Evolution Of The Playstation Controller
I've previously designed a Blynk controlled robotic tank. It connects to a Wi-Fi network and receives commands from Blynk server. A smartphone running Blynk app was used as a remote control, and different input methods were used: push buttons, sliding bars and even smartphone's accelerometer. You can find more about this project here: https:///igorF2/wi-fi-controlled-robot-using-wemos-d1-esp8266-and-blynk-464198
I've also made some experiments with voice commands. It might be usefull if you want to remotelly control a robot without using your hands, or if you want to made it accessible for someone with limited movements. One might think of a robotic voice controlled wheel chair, for instance. A DIY robotic kit was used, along with some of my favourite tools: Adafruit.io, IFTTT and Arduino IDE. Full instructions here:
You can use different kits or even desing your own robots using simple materials, without the need of using complex tools such as 3D printers and laser cutting machines. You can find an example on one of my previous tutorials:

The links above are only a suggestion of where you can find the items used in this tutorial (and maybe support my future tutorials). Feel free to search for them elsewhere and buy at your favorite local or online store.
In previous projects I developed the structure of my own robot, using easily accessible materials (without the need for complex tools, 3D printers or laser cutting machines). You can find this project in the link below:
Later I decided to give a chance for a robotic kit obtained from an online store. You can find a link to the robot chassis at the following link: http://bit.ly/2ycI8fP. If you're looking for a kit, I think it's a good option! I used it in two other tutorials, as you can see on the links bellow:

At first it seemed that the assembly would be complex or that I would run into problems like the lack of parts (given the amount of parts that make up the kit). But this kit really surprised me! All the pieces seem to me of good quality, and several spare parts accompanied the kit. Thus, a screw lost underneath the workbench won't make it impossible to carry out your project, which I found to be excellent (especially after losing a couple of screws).
Another positive point is that all the tools needed to mount the robot are included in the kit (a couple of Allen wrenches and the screwdriver). I believe this makes the kit excellent for starters who doesn't have lots of tools!
Ual (a spreadsheet file in Chinese) is not extremely user friendly, and there isn't a lot of tutorials online for that tank. And so I decided to document the process of assembling my robot in the video above! Another point of attention concerns the material of the robot structure. The base is entirely made of aluminum, which can cause some short circuit if the pins of the printed circuit boards touch the frame.

A power pack made of three 18650 batteries was installed on the back of the robot. It provides 11.1V (3 x 3.7V) to the robot. That's enough to power the 12V DC motors.
A L298N dual channel H-bridge was used for the control of the motors. It receives some 5V signals of the Arduino board, and provide higher voltages for the motors. It also allow the motors to run in both directions, depenting on the combination of those input signals.
A PS2 wireless controller is a great tool for your robotics projects. It has a incredible amount of buttons: 20 digital push buttons and 2 analog sticks. This way, there are endeless possibilities to control your robot.
Arduino Libraries « The Mind Of Bill Porter
It defines a PS2X Class for the controller, which contains some methods for reading analog and digital inputs from the joystick. An object to this class is created using the following code (before or during the setup):
The main functions used from the library are the ones for reading digital and analog inputs. To read and digital input, the following method is used:
To read the analog value (with whill be converter in a integer between 0 and 255) of the sticks use the following method:

With those basic functions you'll be ready to use the PS2 controller on your project! On the following steps I show some Arduino sketch examples combining those buttons!
Old video games, such as SEGA Master System and Mega Drive and Nintendo SNES, didn't have force sensitive buttons. The directional buttons were only on/off buttons. For this firts example, I wanted to emulate the kind of controls one would have in old video games of those consoles.
For the this first Sketch I used Dpad buttons as inputs to the robot. Each button was used by the robot to perform one of the basic movements: move forward, turn right, turn left or move back.
Interfacing A Ps2 (playstation 2) Controller
Those buttons have binary outputs. This way, the microcontroller will only understand that the buttons were pressed, but won't understand how hard they were pressed. This way, once a given button is clicked, the motors will run at full speed.
As I told before, the motor will move at a fixed speed. When turning left or right, motors will run on oposite directions, so that the robot will turn around its axis.
Download the code and open it on Arduino IDE. If you use the same pinout I did, you probably won't have to change anything on the code (although it might be needed, if the orientation of the motors is different

For uploading the code, select 'Arduino/Genuino Uno' board, select the right COM port, plug board on your computer's USB port and upload the code.
After the upload was complete, unplug the USB cable, and put the batteries. The code will start running and the Arduino board will automatically connect the PS2 joystick. Open serial monitor at first use and check the status of the connection. If it fails to connect with the joystick, there are somethings you should do:
Define the pins of the Arduino connected to the h-bridge. If you use the same connectios I did, you'll have the following configuration. If you choose to use different pins, update this part of the code.

The first thing I did during the setup was to configure I/O pins state (as output) and set enable pins to LOW. This way you'll disable both motors on start-up, and the robot won't move randomly while it waits for the rest of the code.
Then I started Serial port communication (usefull for debuging the code). Choose an appropriate baudrate and set the same speed on the Serial Monitor.
Finally, configure the ps2x object with the pins of the Arduino that were connected to the joystick receiver (clock, command, attention and data respectively). It might return an error (to be displayed on the Serial monitor). The type of the controller will also de displayed (although you probably already know the type of controller you have in your hands at this point :D).

During main loop the Arduino will read each D-pad button (UP, DOWN, LEFT and RIGTH) and set the different values for the output pins, in order to move the wheels. After a quick delay, a new loop is started.
The following section shows how to move robot forward if UP button was pressed. MOTORA_1 and MOTORA_2 pins define the direction of the rotation for Motor A. ENA will define if the movement is enabled or not (motor ON/OFF). Notice it is an analog output (actually a PWM one). It's value should be something between 0 and 1023. This will modulate the PWM, and change the average voltage at the output of the h-brigde (between 0 and 12V). If the average voltage is too low, the motor won't be able to move at all.
*I used PWM outputs for the ENA and ENB pins. This way, 1023 would represent a pulse with the greatest lenght (pin always on) and 0 the absence of pulses (pin always off). If a different (smaller) value is used here, the motors are expected to run slower, since the average voltage in their terminals will be smaller.

At a given time, all consoles adopted joysticks with two analog sticks. Those new inputs allowed force sensitive inputs that created variable speed actions and became popular in every kind of video games.
In this second example I wanted to use an analog switch for steering the tank, and
