I am a newb to arduino but I know the basics. So could you guys tell me what project I should start with.
-
What are you interested in ?
-
What projects have you made in the past ?
-
What hardware experience do you have ?
-
A Servo Motor project is fun to make.
What does that mean? Welcome to the Arduino forum. Please introduce your self and what have you done with electronics and computers in the past? Do you know the basics of program design?
Not OP, but I would be appreciative if you could elaborate a little, or provide a link. I assume that what you have in mind would be something more involved (and more "fun") than just sending some kind of PWM signal from the Arduino to the motor inputs...

I am interested in how to use an ultrasonic sensor and a temp and humidity sensor. In the past, I have made an interactive led lamp and am making a remote control car.
I also need help building the remote control car. I think I have all the supplies:
dc motor
servo
ir reciever module
remote control
Lego frame
Arduino uno
That means I only know the basics of coding but not the coding required for complex sensors.
- Show us good images of your hardware components.
- Do you have a DMM ?
- Do you have a 6V AA battery pack ?
- Do you have soldering equipment ?
-
Okay, here is your next project:
Enter a 3 digit number (followed by #) with the IR Remote to make the Servo move to a servo position 0 to 180°. -
Draw a schematic showing us how you will connect this project’s components.
could you explain a little bit more.
We need to see a good image of your available hardware.
What do you need more information on ?
- Enter a 3 digit number (followed by #) with the IR Remote to make a Servo move to a servo position 0 to 180°.
- Draw a schematic showing us how you will connect this project’s components.
We never power a motor from an Arduino or 9v battery.
- Suggest you buy a 4 X 1.5v AA battery holder. (6V)
I need more information on the code part.
By the way. How do you post an image on the arduino forum.
- Your sketch should look for an IR receive chacter from your IR remote.
The code should collect up to 3 digits, 0-180, then move the servo to that position. Also, the # is to be used as a terminator.
example:
0# (EQ) will make the servo move to position 0°
30# (EQ) will make the servo move to position 30°
120# (EQ) will make the servo move to position 120°

thank you 
- Hint, if you have an IR remote that uses the NEC protocol, start here:

- When you get the sketch in the previous post working, confirm your IR remote button codes with those in this chart.
