Stripboard – how to solder quick prototype for DIY project

DIY project usually is prototyped using breadboard. Big mess of wires, and some chips between :) It is very convenient build it that way. Rewire connections? No problem, just switch some wires. However, when project is done and You want to use this prototype in the filed, it turns out, what was advantage has suddenly […]

Wireless temperature sensor programmed with Arduino IDE

tinyBrd is small development board, with ATtiny84 and NRF24L01+ connector. With software provided by us, You get easy to use board which can send data by radio to Raspberry Pi or Arduino UNO and run many days (our most recent tests show it will run at least 2-3 weeks in this scenario) on single CR2032 […]

What new we have learned about NRF24L01

In recent weeks we did a lot tests to our tinyBrd. This was due to new Nettigo tinyBrd Core (integration with Arduino IDE). With v1.1b release we have lowered current consumption even more. Now, in sleep mode tinyBrd with NRF24L01+ and DS18B20 takes only 4-5 µA (vs 9-10 µA on previous software). During sending data […]

Using tinyBrd library on Arduino to connect via NRF24L01

Our tinyBrd has very simple and easy to use interface for NRF24L01 radio. This library was bundled with Nettigo tinyBrd Core, add-on for Arduino IDE to program tinyBrd. Now we have extracted it as standalone and can be used on Arduino UNO and other boards. Changes are minor, since we need to remove name conflict […]

Arduino YUN – how to get older system images

On  You can always find and download most recent Arduino YUN system image (firmware).  What to do, if You need older one? Older firmware for Arduino YUN First, You need to know which firmware You need. Browse all release notes on  GitHub. Knowing which one You need, insert revision number into link replacing XXX: […]

tinyBrd – NRF24L01 radio connectivity in Arduino style

Check tinyBrd page All, most current and up to date documentation can be found on tinyBrd documentation page: (since Mar 2016) Previous content: At Nettigo we did a lot work with NRF24L01. As a result we created small board, with ATtiny84 on board and connector for NRF24L01. This board is Arduino IDE compatible (You […]

Serial port busy for avrdude on Ubuntu with Arduino Leonardo Eth

Doing test with new Arduino Leonardo ETH on Ubuntu (14.04) we had problem with programming this board: avrdude: ser_open(): can’t open device “/dev/ttyACM0”: Device or resource busy avrdude: ser_send(): write error: Bad file descriptor Problem uploading to board. See for suggestions. On Ubuntu (or other distro with ModemManager) ModemManager tries to connect to each […]

Debug sketch on Arduino Zero Pro with GDB and OpenOCD

Arduino is simple platform but empowers it’s users to do fantastic projects. People with experience in writing software for bigger computers can get strange feeling when they have no access to debugger. Debugger is tool for tracing program execution – You can examine/modify variables, going through code step by step and many more. In other […]
