Robot control with Python

Fire four solenoids, spin two DC motors or step one bi-polar or uni-polar stepper with 1.2A per channel (3A peak) using the TB6612.

 We really like these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto.

We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on the motor voltage input and a pullup on the "standby" enable pin. Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for 1.2 Amp or less of current, since that's the limit of this chip. They do handle a peak of 3A but that's just for a short amount of time. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver!

There's two digital inputs per H-bridge (one for each half of the bridge) as well as a PWM input per driver so you can control motor speed. Runs at 2.7V-5V logic. The motor voltage is separate from the logic voltage. Good for motor voltages from 4.5V up to 13.5V! This wont work well for 3V motors.

Comes as one assembled and tested breakout plus a small strip of header. You'll need to do some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power supply not included. Check out the handy tutorial on assembly and wiring!

Specifications:

• Current Limit: 1.2A
• Size: 27mm x 19mm x 3mm / 1.1" x 0.7" x 0.1"
• Weight: 1.8g

What's in the box?:

1 x TB6612 driver
1 x header strip

Books at level 3 are intended for young coders that are starting to want to build more involved applications. The first book at this level is Python: Building Big Apps. It introduces Object Oriented Programming (OOP) so that readers become familiar with classes and objects which are extensively used in game programming.

The book does not set out to teach perfect OOP but instead simply aims to introduce some of the concepts and to recommend that building classes allows students to organise their code in big projects in a logical and manageable way.

While learning more theory, readers will build a number of small projects ending with a big project - MyPong. The final chapter will show how building MyPong carefully allows us to quickly and easily build a BreakOut style game, an Invaders game and many more.

In Marshall Trent’s Reunited Kingdom every citizen of New Edgehill has a neurochip implanted within them that links directly to the Neuralnet.

The Neuralnet sees and records every thought, movement and microscopic detail of every life in New Edgehill. Absolute control!

Cal Jones believes he is no different from everyone else. That is until he saves the life of Sasha and learns that everything that he thought was true is in fact a lie. He discovers an underground group, the Anarchists, living outside of the Neuralnet and harbouring a secret which will change his life forever.

Matt Langley has written a fantastic, imaginative and exciting novel for the Coding Club series. You can even read the first Chapter now: http://codingclub.co.uk/uploaded_pdfs/BlackFlag_sample.pdf

Join Danni as you train as an Anarchist

This is a Coding Club mission. This means that you can get far more involved in this book than any other you have read before – should you wish to. To register for free, all you need to do is enter an activation code and fill in a short form. Unfortunately we cannot just leave activation codes in plain view. You will have to visit the Black Flag website and think like a true hacker – ignore the visuals and dig into the code!

I will guide you throughout your training as an Anarchist agent. You will solve many of the assignments that Cal, Sasha and I face in our struggle. Do not worry if you are still a novice programmer, there is lots of guidance and hints along the way.

All the preparation that is necessary is that you have worked through Coding Club: Python Basics. Alternatively you should be fine if you have learnt a little Python 3 some other way. You simply need to have a grasp of how to write variables and functions, perform simple maths operations and manipulate strings. You should also know how to save and load files in IDLE.

It is not going to be easy, but trying to save the World never is!

This is the Python: Interactive Adventures home page. Answers and full source code are found in the resources page.

Python: Interactive Adventures is the latest book to be added to the series and provides more material at level 2 for programmers at this level. It is written as an alternative and extension to Python: Next Steps. The material introduced at this level is very powerful and enables young programmers to produce a whole variety of exciting Apps but many students will want to consolidate by studying both level 2 books before moving on. While both books introduce tuples, lists and dictionaries Next Steps also delves into building and designing sophisticated GUIs. Interactive Adventures, on the other hand, explores how to go about breaking longer programs into manageable tasks which are easier to approach or share among a group of friends.

In the first part of this book you write a card trick script, create a small e-book reader and an app to help you encrypt and and decode messages. The big project involves building an interactive story based app that you can then customise with your own images, story and puzzles. The bonus app provides a short interactive mystery story, with a heap of special effects you can explore and add to your own apps.
