Hi connection scheme is on picture above

Hi, yes correct all sensor signals into one input on Arduino. if you want to make it separate first it need to follow data sheet from LM358, this chip have 2 output and 2 input signal, or if you want to make 1 sensor 1 chip also no problem, example 2 pcs sensor and 2 pcs LM358, follow the schema the signal from sensor goes to --> LM358 Input, and output from LM358--> go to input digital Arduino and declare from the arduino sketch, maybe example you can put signal Sensor 1 into D7 and Sensor 2 to D8 if (digitalWrite (sensorPin_1)==HIGH){ // maybe turn on led, or send signal "1" to pc }if (digitalWrite (sensorPin_2)==HIGH){ // maybe turn on other led, or send signal "2" to pc }below is picture,But if you have more budget you can buy IR sensor E18D80nk, more easy...

Yes, you can connect output sensor (from lm358 write d7 on the picture step no 5)into input pin 7 on arduino, and other is only output led using pin 12 and 13 on arduino

Thank youu

thank youu Robertus

amazing, super works, i like it, thanks for share

Geniusss and fun :D :D, thanks for shared

This is really cool, great job, voted for you

maybe im late, but i like it , thanks for share

Thank you for shared, i like it

Good job, i like this, thanks for shared

Thanks for shared, this i need

i like the idea, great, i think not only object in the sky, we can trace anything, i will make it too i will paint my girl :D, thanks for share

wow great works, you a master, thanks for share your instructable

This is what i need, thanks for share is nice idea

Nice photos and instruction, thank you for shared

:) will be goo

wow is brilliant idea, thank you tbt10f, is pleasure if you can share other pickpox will be interesting :)

nice idea obillio thanks, i will keep noted for further pickpox

awesome your hand very talented, thanks for share the video

nice works, its mature combining

i like this, cool

Thank you CraftAndu :)

Nice idea too Michael_oz, will give other perspective of view, thank you

Thanks Yonatan24

Amin gratefully, thank you

Thank you AlexAndAmigos

yes Paul, i really appreciate it, thanks :). and you are correct is cheap, you can try this, and share if you have done too.

:) thanks

gracefully, you are welcome annrr

wow you are right i will noted for further develop, thank you for idea

Hi Brian, interested project, how is maximum degree can achieve (cool & hot ) ? and how long your battery can hold ?, i will keep your instructable maybe i need to develop something :), thanks for shared

Youre welcome 38ren, hmm nice idea to put some paint :)

Thanks gm280
