i have tried to make flex sensor at home by using aluminium foil , jumper wires,glu, white paper with pencil shade . I have followed all the insteuction in found in google in order to make flex sensor. But i failed to make it . i have tried to make it atleast 10 times but it does not work . I have also checked the circuit connection and found nothing wrong there. Can really a flex sensor be made at home ? Please help me.
