Hello,
I am wondering if it would be possible to add a DS18B20 temperature sensor to my SparkFun WiFi IR Blaster.
I know i have to connect the GND and a 3V or a 5V supply but i do not know where i should connect the data wire.
Thank you,
Hi iondarie,
You should be able to connect the data wire to one of the I/O pins broken out on the WiFi IR Blaster but I’m not sure if all or any of them are compatible with the [OneWire Library. You can test by modifying the [Temperature Example and switch the “ds” pin just remember to add a 4.7K pull-up resistor in series with the data line.](https://github.com/PaulStoffregen/OneWire/blob/master/examples/DS18x20_Temperature/DS18x20_Temperature.pde)](GitHub - PaulStoffregen/OneWire: Library for Dallas/Maxim 1-Wire Chips)
