Tutorial about Flex Sensor and ARDUINO
Flex sensor and ARDUINO UNO:
The flex sensor are sensor that change in resistance depending on the amount of the bend on the sensor. They convert the change in bend to electrical resistance, they are usually in form of a thin strip from 1" - 5" long that vary in resistance and they can be made uni-directional or bi-directional. These flex sensors are being patented technology by spectra symbol. Also this flex sensor can be used to do prototype and use for a lot kind of enterprise, work on computer, for the movement of the hand and other thing based on technology and also is a good option to use in the future when you use a computer and without the need of a keyboard, just can use these to move everything with the use of the hands. In this investigation I work with the Flex Sensor to find how is the range of inclination and degree about the fingers, also do a simulation about the hand on computer including an accelerometer for a future time, also this can be use for robotic experiment.
Here is a tutorial of how is connect the cables to the ARDUINO UNO and the Flex Sensor with the port cable.
Materials:
1. Flex Sensors
2. Wires
3. Resistance (2.2 to 10kohm)
4. Card ARDUINO UNO
5. Glove for the Flex Sensor
Connection:
1. Place ARDUINO UNO to computer.
2. Connect the wire to the Flex Sensor using welding.
3. Connect the resistance to green cable using welding.
4. Doing the step 3 connect other cable to resistance and connect to the annalog.
5. Doing the step 3 to 4 connect another wire to resistance and connect to GND.
6. Connect the white wire to the 5V.

Flex sensor y el ARDUINO UNO:
Los flex
sensor son sensores que tienen cambio de resistencia dependiendo del aumento de
la curva de los sensores. Estos se convierten en un cambio de cambio a la
resistencia electrica, tambien son usualmente en forma de una tira fina y
tienen un largo de 1" - 5" que varia en la resistencia
y también se pueden hacer en forma uni-direccional o o
bi-direccional. Los flex sensor son echos y patentizados por spectra
symbol. también los flex sensor se pueden utilizar para hacer
prototipos y usarlo para diferentes tipos de empresas y trabajarla en el
uso de una computadora, para hacer movimientos de la mano simulados en una
computadora que sea basado todo en tecnologia o robotica, tambien para el
futuro cuando se este usando una computadora no tengas que utilizar el teclado
y solamente trabajes con tan solo utilizar las manos con este tipo de sensores.
En esta investigacion estuve trabajando con los flex sensor para encontrar el
rango de inclinacion y el grado de los dedos, tambien hacer una simulacion de
la mano en la computadora incluyendo el acelerometro para trabajarlo en el
futuro, también utilizarlo para experimentos de robotica.

4. Hacer el paso 3
conectando otro cable a la resistencia y conectarlo al analogo.
5. Hacer el paso
