HobbyTronics | Hobby Electronics Components Supplier for your hobby and education needs Covid-19 - IMPORTANT UPDATE We are still open, and are still trying to get your orders out as quickly as possible. A couple of notes on expected service: We have implemented social distancing measures and staggered shifts in the workplace. Consequently, our usual ability to turn around orders has been affected as we adapt to these new conditions. This means that it is less likely that we will be able to dispatch your order on the day it is delivered. Secondly, we have been experiencing unprecedented delays with Royal Mail. Finally, while most of our suppliers are still open for business, we have been facing some supply chain issues due to the pandemic. If you order a custom stencil or custom laser cutting, please make sure to follow the instructions on the product page as closely as possible to avoid additional delays. We hope you understand the necessity of these measures in this difficult time, and look forward to returning to normal when the crisis is over. Latest Products

Arduinology herbie555 asked: I'm attempting to use WiFlySerial 1.08 with a RN-XV and a Sparkfun ProMicro 3.3V.Wired using the standard pins 2,3, but all my sketches, including WiFlyTest, are hanging at/around the first call to WiFlySerial::begin(). I've checked the wiring continuity and experimented with swapping the pin assignments (3,2 instead) and changing the default baud rate, but I simply cannot get past this first step. 2 RN-XV boards, so I'm reasonably certain it's not a damaged unit. Anything else I can try? Hi Herbie555, WiFlySerial does look for the version number of the RN chip firmware… RN’s send it as part of their command prompt. Set the library’s version number to your RN’s firmware version … might help. Let us know either way!

Adafruit DS3231 Precision RTC Breakout The datasheet for the DS3231 explains that this part is an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. This is the finest RTC you can get, and now we have it in a compact, breadboard-friendly breakout. Comes as a fully assembled and tested breakout plus a small piece of header. A coin cell is required to use the battery-backup capabilities! Check out our detailed tutorial for pinouts, assembly, wiring & testing, and more! Technical Details Datasheet23mm x 17.6mm x 7.2mm / 0.9" x 0.7" x 0.28"Weight: 2.1g Learn Repent and temperature-compensate your oscillator, said the tick-tock man!
Arduino Pro Mini with RFM12b Arduino pro mini + wireless transmitter= good fun! The previous breakout board I have produced can be used to interface the RFM12b to a controller such as the arduino pro mini. The RFM12b is a single chip, low power, multi-channel FSK transceiver designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 433, 868 and 915 MHz bands. a version that requires an external whip antenna: a simple wire soldered on the proper pina version that includes a chip antenna (printed on the board): no need for an external wire Because there are 2 versions of the RFM12b you need to use a wire of the proper length: for the 433MHz range @ 1/4 wave = 164.7mmfor the 868MHz range @ 1/4 wave = 82.2mmfor the 915MHz range @ 1/4 wave = 77.9mm In this snapshot I soldered two breadboards with an 868MHz (the red wire) and a 915MHz (the blue wire), they sit nicely on a standard breadboard for prototyping.

Cairo Hacker Space: A beginner’s guide to connecting and operating the WiFly to Arduino Serially We were working on a home automation project , we used the wifly gsx in our project .When we bought it, we thought it will be easy to communicate it like a serial modem between the arduino and PC ,,, of course we are not noobs :) but every inch in the datasheet made us feel like one :)And when we searched for a solution for even one of our countless problems we faced.... the result can be summarized in three words ... WIFLY NOT WORKING or we are noobs :D Of course i am kidding :) ,,we are not noobs and wifly is WORKING :o , thanks to sparkfun wifly library and We decided to start our new virtual hackerspace with this easy step by step tutorial for wifly :Please post any problem you faced with wifly or arduino . boolean initSettings() WiFly.SendCommand("set wlan auth <value>","AOK"); //WiFly.SendCommand("set wlan key <value>","AOK"); WiFly.SendCommand("set wlan channel <value>","AOK"); WiFly.SendCommand("set wlan join <value>","AOK");
RN-XV WiFly | niltoid.niltoid. The RN-XV WiFly Module from Roving Networks is an affordable way to go wireless with your Arduino project. It’s $35 and you only need 1 to get started, assuming you have a wi-fi adapter in your computer as well. Previously, only the more expensive options such as the WiFly GSX ($85) were available. I’m not sure, but I assume the price difference is mainly due to signal strength differences. There are currently more resources and Arduino libraries available online for the WiFly GSX or WiFly Sheild, since they’ve been around longer. However, the RN-XV is gaining popularity fast and I hope to see future versions of these WiFly libraries work more reliably for the RN-XV. If you don’t care about connecting to a wi-fi network, and instead want simple point to point wireless serial communication, another alternative is the hugely popular Xbee Module. But back to the RN-XV. I started out by attaching a bread board to my Robot Chassis. RN-XV VCC (Pin 1) – Regulated 3.3V RN-XV GND (Pin 10) – GND
Getting started with the RN-XV WiFi Module & Node.js | Limina.Log The RN-XV WiFi module is a nifty little WiFi module designed to fit the same pinout as an XBee, so it’s intended to be a drop-in replacement. Tonight I whipped up a little test of the module to get a joystick to talk to a Node.js server over WiFi. I attached +3V power and ground to the module (pins 1 and 10, respectively), pin 2 (TX) to Arduino digital pin 0 (RX), and pin 1 (RX) to Arduino digital pin 1 (TX). That’s all the hardware setup you need. I used this WiFly library to handle the connection. nodeArduinoWiFly / Ted Hayes Talks to a node.js server via a Roving Networks RN-XV WiFly module.Full description: WiFly Shield Library: #define PIN_VERT 0 // analog#define PIN_HOR 1 // analog #define PIN_PUSH 2#define PIN_LED_RED 3#define PIN_LED_GRN 4#define PIN_LED_STATUS 13 // onboard LED int vert = 0;int hor = 0;bool push; delay(100);} Related Posts:

Using the RN-XV WiFi Module as a Remote Switch | Limina.Log It’s been a struggle, but I finally figured out how to use a Roving Networks RN-XV WiFi module as a remote switch. It’s not hard now that I know how it works, but figuring out was quite difficult, as the manual is apparently incorrect and the firmware it shipped with was causing problems. Read on for the solution! Hardware Simple! Here’s all you need: An XBee breakout board (so you can plug it into your breadboard)An XBee Explorer (not necessary with ad-hoc mode, but I had one around so this tutorial will use it)3.3V regulator (ONLY—the module has a 10% tolerance, so anything beyond that will either not work or damage the module).10µF and 0.1µF capacitors for good measure (clean power is especially important when using radio devices)Power and Ground (Pins 1 and 10, the top and bottom pins on the left side of the module)An LED connected to pin 9. Setup With your module plugged into USB, open up the port in CoolTerm. set wlan phrase <your wpa password> set wlan ssid <your ssid> save reboot
Using the WiFly RN-XV from Roving Networks Hi following on from this post by Chris A. I have been using the WiFly RN-XV module from Roving Networks as a telemetry link to the APM 2.5. I have to say this unit is amazing at it can be configured in so many different ways. Due to it's flexibility the WiFly can be somewhat daunting to configure. This is the simplest configuration and is great at home when you have an available WiFi network. To configure the WiFly connect it using an FTDI cable to your computer. The default baud is 9600, to connect i run Terminal and the command screen /dev/cu.usbserial-AM01RMWT 9600 type $$$ to enter setup mode. Option: Infrastructure TCP factory Rset uart baudrate 57600set wlan ssid YOUR_SSIDset wlan phrase PASSOWRDset ip flags 0x6 (means TCP connection closed on disconnect)set uart baudrate 57600save infratcp (save it with a name, so easily switch configs with load later)savereboot Option: Soft AP Hope this helps :-)
