Here is a companion tutorial to go with the ADC tutorial. The ADC ports on the EZ-b v4 can host a number of different kinds of sensors that run on 3.3 volts. There are some sensors however that need a helping hand to work and the v4's analog ports, and flex sensors are one such sensor.
In this tutorial, I will go through the steps for how to get a flex sensor up and running on an ADC port.
It's a pretty straight forward process and only requires a few parts, which are...
A 1x Flex/Bend Sensor,
One 10 Kohm pull up resistor,
A soldering iron and some solder (preferably lead free solder to keep you healthy),
One servo extension wire,
A pair of wire cutters/strippers,
And an EZ-B v4 with power supply and ARC running on your computer.
You can use a solder-less breadboard or make your own circuit board.
The following steps will now guide you through the process.
