Hi,I use arduino uno ,e-Health platform and the GSM shield
I have this problem:the TX end RX pins are used with the e-Health shield
and the GSM must be connected with arduino uno with TX and RX too,and the arduino UNo have only 1 TX RX
please help me :How can I use at the same time arduino uno with GSM shield and E-Health platform using more than 2 TX and RX ???(note:the digitals pins are all used by the e-Health sensors)
