Pong is one of the earliest arcade games, released in 1972.

In this guide, you will build a hardware controller using a Raspberry Pi to play the old-school classic, Pong.

Complete this guide to get started and make customisations to your build.

Step 1 Fitting the Cobbler

This is the Pi T-Cobbler. It breaks out the GPIO pins from the Pi allowing us to connect cool stuff

Firmly press the cobbler into the breadboard making sure the first 5.0v pin is in H1

Step 2 Fitting the ADC

This IC (integrated circuit) is an analog to digital converter allowing us to read analog inputs into our Pi

Line up pin 1 (marked by a small indent on the plastic) with E27

Press firmly into the breadboard

Step 3 Fitting the knob

This is a potentiometer. It will be our analog input.

Press it into the breadboard as shown with the first pin in A44

Step 4 Wiring chip select

Connect J12 to J33 using a yellow jumper wire

This is our chip select line

It tells the IC when it can send data

MCP3008 CS/SHDN to Raspberry Pi CE0

Step 5 Wiring Analog Input

Connect C45 to C27 using a green jumper wire

This is our analog input

Step 6 Wiring data clock

Connect J30 to B12 using a yellow jumper wire

This is our data clock, it allows the Pi to synchronize data transfer with the IC

MCP3008 CLK to Raspberry Pi SCLK

Step 7 Wiring MOSI

Connect C10 to H30 using a green jumper wire

This is our MOSI (Master Output Slave Input)

It allows the Pi to talk to the IC

MCP3008 DIN to Raspberry Pi MOSI

Step 8 Wiring MISO

Connect G31 to A11 using a blue jumper wire

This is out MISO (Master Input Slave Output)

It allows our IC to talk to the Pi

MCP3008 DOUT to Raspberry Pi MISO

Step 9 Wiring VDD

Connect the RED power rail to I27 with a red jumper cable

This is providing power connection to our IC

MCP3008 VDD to Raspberry Pi 3.3V

Step 10 Wiring Vref

Connect the RED power rail to I28 using a red jumper cable

This is our Vref

It provides a reference voltage to measure our analog input against MCP3008 VREF to Raspberry Pi 3.3V

Step 11 Wiring AGND

Connect the BLUE power rail to G29 using a black jumper cable

This is our analog signal negative (ground or GND) connection to the IC

MCP3008 AGND to Raspberry Pi GND

Step 12 Wiring IC Ground

Connect G34 to the BLUE power rail with a black jumper cable

This is our negative (ground or GND) connection to the IC

MCP3008 DGND to Raspberry Pi GND

Step 13 Wiring negative to the knob

Connect the BLUE power rail to B46 with a black jumper cable

This is our negative (GND) connection the the potentiometer

Step 14 Wiring positive to the knob

Connect the RED power rail to B44 with a red jumper cable

This is our positive connection the the Potentiometer

Step 15 Wiring GND to the Pi

Connect the BLUE power rail to A20 with a black jumper cable

This allows the raspberry Pi to share a ground (negative, GND) connection with the rest of our circuit

Step 16 Wiring 3V3

Connect the RED power rail to A1

This provides power to our circuit from the Pi
