@Arun Since your question is more related to design, please create a new topic on the RobotShop Forum and we would be happy to help.

Hello sir/madam,
Please send me information that how to interface the GP2Y0A02YK0F sensor with arduino for swipe gesture,if you have the code example related to it then do send me.I will be very thankful to you,i’ll be waiting for your reply.

83

@mustafa The GP2Y0A02YK0F is an analog sensor, so you can use a normal analog pin (and code) for input. What you do with that distance value (within your code) is up to you.

84

I have a stop watch timer displayed on an LCD screen I’m trying to figure out how to have the clock stay at zero and trigger from an IR sensor on an analog pin. any suggestions would be great my timer currently runs continuously until the reset button is pressed on the UNO

85

@Patrick Reynolds The question is quite application / code specific, so rather than having a conversation here, it’s best to create a new topic on the RobotShop Forum (such as here or here) with details of the parts you have, and what you’d like to do.

86

hello, i need to interface an OPB732 sensor with arduino and sent directly the distance readed on another arduino board, can you help me please !!

87

@meriem If you plan to create your own circuit, you’ll need additional components as detailed on page 4 of the manual. Note that it will not provide you with distance but rather an analog value for time of flight. If you’re new to robotics and it’s a project for yourself, this is not the easiest to start with.

i’m not new i’m a student in electronics engineering (master 1)and i need that for my final project, so it would be very kind of you if you can help me with that :slight_smile: i tried this program but i get values between 1023 and 800 and it steel changed it not stable at all even when i totaly cover the sonsor

@meriem Unfortunately we cannot really offer support in the comments section here. Feel free to post your question on either the RobotShop Forum or on letsmakerobots.

if it is possible to get the count value of encoder after completing the loop???
Actually i need to display the encoder value when the sensor is triggered

91

@Parthi Of course that’s possible. You have a counter and output the value when triggered.
