- This step is pretty simple: screw the buttons into the control panel, connect each button to a USB encoder, and plug the USB output into the Raspberry Pi. Once your controls are ready to go, simply.
- So, soldered all the connections, plugged in the power to Raspberry Pi's GPIO pins and off we go! So, everything in this project (display, sound, lights) are powered from the RPi. Designed the removable panel to allow the amplifier to be mounted and you can adjust the volume using a small knob.
A DIY Raspberry Pi vending machine has been created by Christopher Natan using a little Arduino programming and hardware. Full instructions on how the project is created have kindly been published to the Hackster.io website available via the link below.
The Raspberry Pi vending machine is capable of sending Top-up to any prepaid mobile (Globe, Smart, Sun) networks and can also serve as a wireless hotspot. The project uses a number of programming languages including Android Java, CakePHP Framework, PHP, MySQL, nGinx, Python3, NodeJs and Shell Script.
Hardware used in the build include Raspberry Pi 3, Coin Acceptor, APEX 7000 Bill Acceptor, Channel Relay, OptoCoupler, Android, Modem Router that supports flashing to OpenWRT firmware and a 10 inch Android Tablet which has been rooted and only allows one application to be run. Check out the video below to learn more about the project and see it in action.

The Raspberry Pi is a powerful tool when it comes to artificial intelligence (AI) and machine learning (ML). Its processing capabilities, matched with a small form factor and low power requirements, make it a great choice for smart robotics and embedded projects. Google is a champion of the Pi’s place in the AI world, its AIY voice recognition system being given away with this very magazine (issue 57, no longer available in print).
You can now buy Google's AIY projects and newer Coral AIY products for Raspberry from Mouser.co.uk
Google’s AI Education site is an ideal place to start your machine-learning journey. If you want to really understand how AI/ML works ‘under the hood’, there are lot of principles to comprehend before you even get to coding. Google has provided a self-guided suite that starts with a ‘Crash Course’ in machine learning, then expands to cover the basics of problem framing and data gathering. The main online course comprises 25 lessons over 15 hours (approximately, you can set your own pace) and comes in the form of reading materials, interactive sections, programming exercises, and video tutorials. This is then backed by a substantial collection of follow-on courses. A superb resource.

Complete Guide to TensorFlow for Deep Learning with Python
TensorFlow is, without a doubt, the most popular software library for machine learning on the Raspberry Pi. If you’re keen to get started and write code, TensorFlow will probably be your tool of choice. You can get a great introduction to TensorFlow in The MagPi #71, but if you are after a deep dive, Udemy offers a comprehensive 14-hour video course that covers not only the theory of machine learning, but also the practicalities of setting up the software with real-world examples and programming exercises. If you’re after a hands-on learning approach, this may well suit. Don’t be put off by the steep (£195) price – this course is often promoted and was £13 at time of writing.
Beginning Artificial Intelligence with the Raspberry Pi
This book is perfectly tailored to the Raspberry Pi community. Not only does it cover the principles behind concepts such as neural networks, fuzzy logic, and shallow versus deep learning, it also provides practical, fun projects to code and build. Starting with simple examples of learning, you can play your Pi at noughts-and-crosses and Nim. Along the way, the projects are made fun through the use of the Pi’s GPIO header, using LEDs and switches to bring code to life. You then progress to robotics, covering obstacle avoidance and light seeking. A steady learning curve culminates in the building of ‘Alfie’, your very own artificially intelligent robot vehicle. If you fancy building the winner of the next Pi Wars, this could be the perfect reading material.
