I want to do on Arduino but I havn’t any Idea to Start please help me

@Aemiro Mekete Try an Arduino kit: https://www.robotshop.com/eu/en/arduino-kits.html

i need help in making project. i want to make a seven segment with a 7447 decoder. There must be an input switch, that when pressed should display digits in ascending order like,0,1,2,3… but when the switch is not pressed(open), the digits should go in descending order… plz help me

sir,can single arduino board control both load cell and solenoid valve??.please answer this question.because i am doing a project using arduino board.

45

@saran: Yes, but not directly. Load cells usually need to be amplified (their output is usually changes by a few millivolts when under tension) for the Arduino to be able to read them. For this, you can use a Wheatstone Bridge amplifier, such as this one. Solenoids tend to require quite a bit of current and Arduino GPIO (General Purpose Input/Output) pins cannot provide enough (usually around 15-20 mA at most). You can solve this issue by using an H-Bridge chip or relay or in a board/shield format to give more current (or a transistor and a few resistors directly, if you feel up to it).

@kanza kazi: We recommend that you post on our forum or on our project-oriented website, Let’s Make Robots about your project and the challenges you are facing. To ensure you receive good advice/help, make sure to list all the things you already tried and attach any project files/code that you already worked on. It is easier to receive help with a problem when the issue is very specific.

sir,how to interface the arduino board with solenoid valve?

48

@hasana You might use a DC relay between the solenoid and the microcontroller.

I’ve been looking all over for information about how to do LED lights with arduino or raspberry pi. What’s the best way to make the LED light up in response to music? Do you know of a tutorial for that?

50

@Fred Spackleton We don’t have any specific code for such an application; you’d need to know what aspect of the music to “respond to”; is it the volume or a specific frequency?

I m happy to learn Text

i need a code for my voltage & current sensor in arduino… could you help me?

53

hi >>>i want to design indoor monitoring system using imu sensor >>give me the step of doing this …thanks

54

@habeeb Unfortunately we do not provide sample code for specific (personal) applications. We suggest you create a new topic on the RobotShop Forum and provide a list of all of the parts you have and what you want to do.

55

@esra We cannot offer design advice here - can you please create a new topic on the RobotShop Forum and provide details of what you want to do?

56

thanks very much i have got something.

57

Is it possible to simulate without a real arduino board?

58

@Athira V K There are certain online Arduino simulation programs available. For example take a look at 123d.circuits.io

59

I want use Arduino for temperature measuring can i use the USB for data storage; thanks

hi can you say me why my serial port is saying "error opening serial port “com6"” after the upload has been done
