The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind ...

As the Arduino Nano and Micro cost the same ($24.90), deciding ... ever board to build DIY devices like portable environmental sensors or mobile robots, you can't go wrong with the Nano.

The circuit is extremely simple, comprising the sensor, an Arduino Nano, and an OLED display. This device is handy because its voltage output has a known relationship to the gauss level the sensor ...

hacked it in with an Arduino. The video does a wonderful job going into the details, but essentially by using an oxygen sensor with finer resolution (wide-band) and then outputting the appropriate ...

the Arduino Nano and Uno come with several similarities, and conveniently, they can be used almost the same way. You can program them with the same software, and many sensors are compatible with ...
