I just bought a Sensor Shield V4.0 and a SainSmart 1602 LCD Keypad Shield for Arduino UNO.
The SainSmart 1602 LCD Keypad Shield wokrs great when connected directly to the UNO. But when I installed the Sensor Shield V4.0 in between the UNO and the LCD keyboard Shield the LCD Keyboard Shield didn't work properly.
I can't find anything on pin usage for the sensor shield.
Thank you in advance.
