Arduino I2C DAC Array Using MCP4725

›

The XBee in line passing mode would output signals via PWM. However, this method is not very good because of the low PWM frequency of the ...

Wireless Movement & Sniffing Monitor

›

Using an XBee, Arduino, and some sensors (accelerometer, pressure sensor), we put together this wireless movement/sniffing monitor. The de...

Sending wireless signals with XBee & Arduino

›

We recently needed to make a system by which we can send sensor data from a freely moving animal wirelessly. One simple way to do this is ...
