I bought a LinkItOne Grove shield v2 and Im interested in connecting it to my Arduino Mega. Is there a tutorial online on how to do so?
I stacked my Grove Shield v2 over my MEGA and copy/pasted the GroveSensor .ino code into Arduino IDE and got readings:
Every 30 seconds…but Im not sure what they mean. Where can I find references to this?
I’d like to know what pins are free for me to use on the MEGA via the Shield. I understand the Grove Shield must use some pins to communicate whatever sensor data I ask of it from my MEGA. I know my MEGA has:
6 Power Pins
16 Analog Pins
1 AREF Pin
1 GND Pin
12 PWM Digital Pins
2 Comm Pins
A bunch of digital pins
But how do I know which pins the Grove Shield uses?
The reason is that Im going to be hooking up a TinySine Wifi Shield on top of the Grove Shield to post this data to a web server and I want to know which pins I can’t interfere with or which ones I have to re-direct in code. And eventually I might also use a GSM/GPRS shield SIM900 in order to transmit the data. I want to make sure what pins a free.
