Projectgroep 20 Biorobotics / Mbed 2 deprecated EMG

Script voor het weergeven van 1 EMG signaal met behulp van een OLIMEX shield. Let hierbij goed op dat je de juiste pinnetjes op het OLIMEX shield verbonden hebt, in dit geval A0 als uitgang. Verder maken we gebruik van 3,3 Volt!

Dependencies:   HIDScope mbed
