How to drive stepper motor with Arduino motor shield

driwing stepper motor with arduino motor shield

Previously we have driven servo and DC motor using an Arduino motor shield. It is easy to interface with these motors and write the code. This time we get to the stepper motor control and discover the full potential of the motor shield. Stepper motors are more complex devices than servos or DC and require some knowledge before running them. You cannot expect to plug some voltage and see it spinning. Their primary purpose is precise stepping that gives control of how much the motor is turning. You can find a stepper motor in any printer which feeds paper incrementally – and this is where you can get one. Disk drives are another great source to scavenge. We will not get into stepper motor working theory. Do your research before trying to run one.

The Raspberry Pi has gone through upgrades and generations, so most of the settings have been simplified. If you set up WiFi using GUI, then it same as on any windows – you select SSID and enter a password. Raspberry pi should be mostly accessed through the console since it is designed to be an embedded computer. This is why it is important to have the ability to do all things in the command line. No matter which raspberry pi you have, you can set wireless networks the same way. If you use Raspberry Pi 1 or 2, you will need a USB wireless adapter. The later boards already come with built-in WiFi and Bluetooth connectivity. To set up WiFi, you need to edit wpa-supplicant configuration file, which can be accessed by entering: To the bottom of file add your network settings as follows: Save settings by pressing CTRL+X and Y to confirm. You may need to reboot your board for the network to connect.

Robotics gets interesting… step by step

The Romford Robot plays snooker. For those unfamiliar with the game, snooker is essentially a two-dimensional activity that involves poking balls around a flat table-top surface with a stick (which is more commonly known as a ‘cue’) and manipulating the angles generated when they hit each other to steer them into holes or ‘pockets’ which are set at regular intervals around the table’s edges. The Romford Robot has, over a period of twenty years, proven to be highly effective in calculating the speed, angle, and spin necessary to excel at the game consistently. All of this would be quite exciting were it not for the fact that the Romford Robot is actually the nickname of a human player. Steve Davis is a six-time world champion and was ranked as the world’s number one player for seven years in succession between 1983 and 1990. Still playing professionally today, Davis has nicknamed the Romford Robot to recognize his hometown – Romford – and the seemingly emotionless and error-free manner he played. For almost a decade, Davis singlehandedly made snooker betting a remarkably consistent investment.

The science behind horse racing

The “Sport of Kings” is one of the oldest and most loved sports in the globe’s entirety. Archaeological records suggest that horse racing was around in Ancient Greece, Babylon, and Egypt’s glory days. It became more of a spectator sport during the Roman Empire, especially under the reign of Caligula. The mad Roman Emperor absolutely loved horses and even got his favorite horse Incitatus a place in the historic Roman Senate: With a rich history, it is of little surprise that horse racing has established itself as the second most popular spectator sport in the UK. In 2013, the iconic jumps meeting at Cheltenham attracted more than 235,000 people, with multi-million pounds spent on the betting. On top of this, many believe that Cheltenham 2015 will be even better supported in terms of attendance and betting. Yet despite its popularity, something that will continue to increase, we take the art of horse racing for granted. Not only do the jockeys that sit in the saddle put themselves at grave risk every race – AP McCoy, the greatest jumps jockey in history, has broken nearly every bone in his body – but there is also a certain degree of science involved…
