Arduino Automatic Time Drawing Robot Arm! |

- This is an automatic time drawing robot arm based on Arduino, which is all 3D printed based on the original PlotClock project by Joo. The robot erases and draws the time every minute using a real time clock (RTC) and an ESP32 as the micro-controller. You can also control the robot arms manually using three rotary encoders. Three 9g servo motors are used for the horizontal, vertical, and lift movements of the robot arms.
In the video, I showcase what is needed and how to wire and assemble the robot so you can easily make it yourself.
Please note, the original idea of this robot is by Joo, which can be found here:

Components needed:
• Three 9g servo motors, I used the MG90S, which have metal gears, but the normal 9g hobby servos will work as well.
• Three rotary encoders with button.
• I used the ESP32 for the micro-controller (MC), but you can choose any that suits the project.
• DS3231 for the real-time clock (RTC).
• A 5v power supply. Remember, you can't use the 5v pin from your MC as the servos draw too much current.
• M2 and M3 bolts and nuts.
• A whiteboard sheet and pen.
To design all the 3D models I used Fusion 360, and printed them using the Creality CR6 SE 3D printer.

Let me know if there is a project you want me to do!
This is dope. Thanks for posting this guide, I really want to make it now!!!
No worries! I am glad you like it. Remember to subscribe if you enjoyed or found the video helpful :)
@@ProjectsWithRed Can you do a project with an esp 32 ble keyboard with this library: github.com/T-vK/ESP32-BLE-Keyboard with buttons
@@levitategamer7151 This is exactly what I did at first actually. But I quickly realised that Bluetooth on the ESP32 uses way too much current. This meant needing a very large battery to run for a reasonable time, which makes it impractical. I even tried using deep sleep, but bluetooth takes a while to reconnect which creates a significant delay on key presses with deep sleep.
@@ProjectsWithRed ok thx
This is awesome, I have started printing and may make some mods after! I will share the results with you :)
Good stuff!
It's amazing, sir 🤩
👍🏼
Nicely done!
Thank you!
@@ProjectsWithRed Actually, as far as further projects, given the ESP32s IoT capabilities, plotting out images or weather info, or whatever would be pretty interesting!
@@createinvent I actually did a project like this not long ago! Check it out using this link (th-cam.com/video/iJIebUzhAIM/w-d-xo.html) or look at my channel for a video measuring air quality. An ESP32 is used to obtain data from 2 sensors which is then being plotted in real-time in the browser and also being saved to the cloud at the same time. Let me know if that is the kind of project you were referring too. If not, give me more details of a project you want and I will for sure consider it!
@@ProjectsWithRed Not exactly - I mean you could use the drawing arms of this one to plot data from the Internet, it wouldn't collect its own data. Though I suppose having internal sensors would be interesting too.
@@createinvent Oh yes, I was actually thinking about that initially, to make it also for example plot/write the temperature and humidity using the DHT11 sensor, but I unfortunately didn't have much time to complete this project. Great idea though to get data from the internet using the ESP32 and plotting/writing it rather then using sensors.
Hey Red! Thinking about taking this project on but making it a little bigger than it currently is…. So I guess that would mean longer arms and a wider case. I’d also like some quieter motors. Would you have any suggestions? Would the code scale okay if I just make the whole thing twice as big?
That's great to hear! In terms of quieter motors, I am not sure, I haven't looked into that before. For the code, yea, it should work totally fine, you may just need to tweak some things but for the most part it will be the same. I hope this helps, let me know if you have any other questions.
When is your next project coming?
The next project will be coming at the end of this week! Sorry for the long wait!
