Hi, just for information, 5v corresponds to a numeric value of 1023 because (0,1,2…1023) = 1024 Values or The max value is (2^10)-1. @From France
hi there,can you tech me how to use this bend sensor with lcd display that showing the degre that sensor bend ?
@syukri Unfortunately we cannot provide specific code. Generally speaking, your code would need to read the analog value, perform a calculation to relate the analog value with the flex, and then use serial output to display the calculated value on an LCD.
In this video on hooking up the arduino potentiometer, it is mentioned that you don’t care which side is hooked up to 5v and gnd. Is that a correct statement?
@John Correct. The center pin is almost always the slider, the the other two are for power. Normally you can provide V / GND to either pin since it’s a resistor.
Plz Explain the reason of blinking of LED with respect to movement of Knob of Potentiometer. As the Knob turned to 0V ; the LED blinks for very short period of time but doesn’t go OFF completely.But the COM3 screen reads 0. When the knob is turned towards 5V the LED blinks for a longer period of time and the Serial monitor screen reads 1023.
the analog readings on my pot are stuck on 250, no matter the wiper position, also the analog pin registers reading around 100 when nothing is connected to it. What could be the root cause for that? I’m powering the arduino with 12v dc through Vin AND have the USB connection plugged in to read the serial monitor.
@Henrik Perhaps the pot is broken (inside)? Check the voltage input range of the pot - you should likely use 5V connected to one end, GND to the other, and an analog pin to the middle / slider pin.
Id love to have answer this.
Write an arduino sketch that will vary the speed of blinking led connected to pin 13 varying the potentiometer connected at A0.
Your answers appreciated 
nice to join this group
i am a beginner . i dnt know anything about tha arduino programming … culd u please tell me how culd i insert tha program to the arduino …how is it done …wich software to b used any after connecting the arduino with the pc wot to be done to insert the program
@jaithra t james You use the “upload” button within the Arduino IDE. To learn the basics, follow the lessons on arduino.cc
Sir,how can I print single hexadecimal value on LCD with from an analog input like multiple pots…?
@vivek negi You need to read the analog value, determine the corresponding hexadecimal value you want to display, then send that character to the LCD. There are a variety of LCDs which accept different inputs such as serial, parallel, I2C, so how you send the character will depend on the LCD you choose.
Hello Coleman, I’ve setup 6 analog potentiometers and now I’m trying to wirelessly send the data from the Arduino to my PC. Any direction you can point me to?
Thanks!
@Georgios Varoutsos You need to connect the Arduino’s TX pin (D0) to a wireless transmitter / transceiver (Bluetooth, RF, XBee etc) and your computer needs to be able to receive that data (so it needs to have a corresponding receiver). There are quite a few more details like baud rate, what to do on the computer side etc., so it’s best to create a new topic on the RobotShop forum and provide details of your current setup.
Hello sir.Could you please give an example on how we can control 2 dc motors with 2 pots,please?
@Jimmy You should not connect the potentiometers directly to the motors - you should use a Dual DC motor controller which accepts analog input (i.e. a potentiometer).
