To connect 3 pin One-Wire temperature senor I had wanted to use the Grove D10-11 port.

Power to 3.3V_SW

Sensor to D10

Ground to GND

Using the ModularSensors code for a Maxbotix HRXL Ultrasonic Range Finder below

it references a  sonarSerial and mentions having to set it up in the “Setting for Additional Serial Ports”  but I am unable to find the correct “settings” to start the serial port?   What are the the best Groove Pins to use, for the Sonic pins?  For a Trigger pin and…[Read more]

I would like to monitor temperature, of water, ground and air.  I was thinking of building one wired sensor to the water, then another wired sensor to ground and air.  Thus I would need two OneWire Bus Pins, .and the one  OneWire Bus pin would have two sensors attached.

Using a few Arduino Example sketches I can get this to work and read, mu…[Read more]
