I bought IOIO-OTG, Grove - Base Shield for IOIO-OTG and some sensors.
According to the pins decribe mapping to the Grove - Base Shield for IOIO-OTG board:
I succesfully run Grove - Gas Sensor(MQ3) (SIG, NC, VCC, GND) connecting A/D to pins 37 & 38 connector.
How does Grove - Alcohol Sensor (DAT, SCL, VCC, GND) connected? To the TWI pins such as 1 & 2 connector? Is this board running I2C protocol? if so, what is the sensor address?
Hi friends,
Sorry for replying so late.
The Grove - Alcohol Sensor is an analog sensor,you should plug it to the analog connector(J7 or J8) of Grove - Base Shield for IOIO-OTG. Here is the more detailed imformation:http://www.seeedstudio.com/wiki/index.php?title=Twig_-_Alcohol_Sensor
