Micro Servo Robot

Wild and EEPROM

hi, any suggestion? my servos are too wild and shaky, Is it because I used 10k ptentiometers? And I wanted it to save it in EEPROM, but i don’t have any idea about it. So I was thinking if you have any refrence you could share to me? thank you :slight_smile:

Replace arduino mini pro with arduino nano in this project

Hello What modifications do I need to do so that I can use this code in an arduino nano instead of a mini pro?

can I use this ?

Can I use this  ?

** @pinaut May I know your**

 @pinaut May I know your contact information? i have some questions want to ask you

Project Entry

Good day! Sir, can I use this project as an entry for our website. Rest assured that I am to credit the entry to you.

go for it :wink:

go for it :wink:

sure. take the 10k Ohm

sure. take the 10k Ohm

and read about analog inputs https://www.arduino.cc/en/Tutorial/AnalogInput

shaky? use a better (more

shaky? use a better (more power [Ampere]) powersuply or battery

EEPROM? an also not have used that. but if i would: i can learn all at https://www.arduino.cc/en/Reference/EEPROM

what all libraries are required?

would this code work in uno?

can you make a tutorial on this or share a website of its tutorial?

I am trying to make Micro Servo Robot
https://www.thingiverse.com/thing:1136876

When I upload the sketch it says I am low on sram memory and the robot may not function. I am using a DFrobot Arduino Rev 3
The actual message is “Low memory available, stability problems may occur.”
Could I delete some of the program, I am using the sketch from the website above

The original robot used a Arduino Pro Mini, I have a 5 volt 16 Mhz but don’t have a board or connector to hook it to my computer, plus the sram is only 2k the same as the DFrobot Arduino Rev 3

When I am using the DFrobot Arduino Rev 3 the robot tries to function,
but the operation is hit and miss, sometimes it does something and sometimes it doesn’t. I’m not sure what the 2 push buttons on the board do.

I have wired in a store/play button and a pause switch.

I am lost,

can I use an ac adapter to power only my motors of output 5-6 v and 2amp

try powering it with extra batteries

low memory is not a problem. if the led goes on and stop your work, just reset the code using the reset button.

the button connected to pin 6 is to teach the arm. if you click it once it will memories the position. if you click it twice it will go to playmode and will repeat what you taught in the same order.
the button connected to pin 4 is like a pause button. it stops all activities.

3 things, firstly, will a mechanoid robot arm, with 4 parts of course, work?
Secondly, will an arduino nano work?
And thirdly, any tips, like code changes or schematic problems, please let me know, thanks!

Guys, I have try to conduct the circuit with TinkerCAD and use the code but when i run the simulation it does not work.

@pinaut is it i have did something wrong on the circuit?

Thanks in advance

hi sir can I see your circuit ?
