Arduino Sensor Applications with Flex
Arduino Sensor Applications with Flex
[nextpage title=”Introduction” ]
Hello friends we have made in this article with a simple Arduino uno flex (flexibility) sensor will let the oil according to the state of the analog value of the applications received from flex sensor.
Used materials:
- Arduino UNO R3
- 2.2 “Flex Sensor
- 3 LED diodes
- 10K resistance (flex sensor)
- 220 ohm resistor (for LED diodes)
It seems that the circuit diagram in the image below.

Arduino Uno
The Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
“Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

The logic of the flex sensors
Flexibility sensors are bent sensor .flex in English at the bend or flex (stretch it) when the sensor resistance of the sensor. flex sensor resistance on metal pads is 2.2 in inside fold, outside the fold “and 4.5” sizes of flex sensors as often we can make this sensor in ourselves.
Below is a simple flex sensor circuit is provided.
