Mars rover remixed and inspired by bolbots mars rover on Thinigverse. http://www.thingiverse.com/thing:1583399
The rover uses an Arduino 101 for brains, BLE for communication, and the Blynk app for remote control.
Intel Arduino 101 based tank with BLE and Blynk!
This project uses the Intel Arduino 101 board that has a built in IMU and (BLE) Blue Tooth Low Energy. For the remote control I used the free Blynk app which is is available for Android and iPhone, it allows you to rapidly drag and drop some buttons to create a user interface. The Chassis is a Dagu DG012 from Sparkfun.
I tried to power the whole rig from the 5 AA battery pack that came with the chassis but the Arduino kept resetting on low voltage. Ideally I would use a nice LiPo battery pack but I think it’s reaching to expect a beginner to learn about the care and feeding of LiPos and purchase a charger so I chose to power the motors separately from the Arduino using a USB Battery pack. Be sure to remove the optional battery jumper on the Adafruit motor shield or you can fry some things, the power sources need to be separate.
Cortana can easily be extended to aid you with your DIY home automaton projects. In this example Cortana sends MQTT commands to open and close a garage door as well as ring the doorbell with custom jingles. By the way, you don’t have to use MQTT, you can also do a whole lot of other things as well from opening a file, opening a program, or launching your favorite websites.
As of the writing of this entry I am frantically trying to finish documenting the MQTT Doorbell and Garage Door Opener devices in separate posts. Hopefully I can get those whipped out in a few days.
The Simple Wi-Fi HC-21 module is a meager $10-$15 bucks on ebay right now. It is a simple Wi-Fi serial port server or virtual serial port. This means it is self contained and will handle all the overhead of negotiating a Wi-Fi connection and communication leaving more room for your application in the Arduino.
X10 Lighting and appliance modules are cheap on Ebay, I wanted to control them with my HMI (ScadaBR) so I put a X10 and Modbus library together in an Arduino to turn on and off the modules.
Thermistors And Your Microcontroller
A thermistor is a simple temperature component, basically it is a variable resistor that the resistance changes in it depending on the temperature. Such a simple device needs a few more components and scaling in the microcontroller to give the desired C or F temperature reading.
A Programmable Logic Controller, PLC or Programmable Controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. http://en.wikipedia.org/wiki/Programmable_logic_controller
A HMI (Human Machine Interface) is the system by which people can interact with a machine. The user interface includes hardware (physical) and software (logical) components.
Building my very first 3D printer was quite traumatic and time consuming but also fun and rewarding! I don’t suggest building your own unless you have a love for tinkering, and making. There are some other qualities that will come in handy such as tendency’s for hacking, electronics, and computers. As this is a computer controlled machine complete with a microcontroller you MUST know how to turn a computer on. Be aware that building your own RepRap is more like getting a hobby than getting a project. Read More…
I’ve seen videos on YouTube using an Arduino and a Graphical LCD screen (GLCD) to create a simple Oscilloscope. The annoying thing is that I found no help whatsoever on how to build one. I spent a few days figuring out how to use the Nokia 3310 LCD screen and then figuring out how to sample an analog port to create a fun oscilloscope effect. Read More…
