WiFi Bot Control is an Android app that allows you to remotely control a robot (or other device) via WiFi. You can also (optional) view a video stream from an IP camera mounted to the robot. WiFi Bot Control also provides up to 8 additional customizable command buttons that allow you to perform additional tasks on your robot / device. You could use these commands to initiate other activities such as enabling/disabling sensors, moving other servos / arms / picking something up, turning a LED on/off etc. With the provided sample sketch, you can customize the robot to do what you want. WiFi Bot Control can be downloaded on Google Play and is compatible with most versions of Android and most device sizes from phones to tablets.
For the sake of this write-up, it’s an Arduino robot using an Adafruit CC3000 WiFi module and a Digistum Motor Shield. However, you should be able to use most other WiFi shields and motor drivers.
Adafruit CC3000 WiFi Breakout with Onboard Ceramic Antenna: The CC3000 hits that sweet spot of usability, price and capability. It uses SPI for communication (not UART!) so you can push data as fast as you want or as slow as you want. It has a proper interrupt system with IRQ pin so you can have asynchronous connections. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP & AES. A built in TCP/IP stack with a “BSD socket” interface. TCP and UDP in both client and server mode, up to 4 concurrent sockets. It does not support “AP” mode, it can connect to an access point but it cannot be an access point. Read more.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
