Look at my PCB. Designed for my IoT project, based on the vocal control of a DC motor using Arduino and a TensorFlow CNN model. The project can be divided into three parts: the CNN model, Arduino and the command circuit, the DC motor...
Your feedback will be amazing!!!
So I did this basic arduino nano project:
Press fingers -> arduino -> nrf 24 transmitter -> nrf24 receiver -> serial communication -> python
I did this with idea in mind to control PC remotely and it is works as good as can rn, but I’d like to hear ur thoughts and suggestions.
Thank you
Moi je suis un débutant et ma mère vient de m'acheter un kit arduino uno débutant et je voudrais savoir s'il y'a des personne qui auront de très bonnes idées de projets

I'm looking for some guidance and understanding of feasibility with an arduino or esp32.
I have a family member who is a fall risk. I am not happy with any of the "life alert" like products on the market which call a service which calls 911.
The Goal: 1 wearable device and multiple button devices which can be mounted near the floor. When a device is pressed it dials her neighbor's phone number, and preferably play some pre recorded message. The wearable device should be small and rechargeable or a long lasting small battery. The mounted devices will be stationary and can be larger, but should be innexpensive enough to have a lot of them and not rely on being near an outlet (rechargeable or easy to replace battery).
Ideas/Brainstorming so far: the mounted an wearble devices connect to one central control system which does the dialing. I think bluetooth would work well which is why I'm thinking of using esp32. I could also have them relay a message to the controller or send a broadcast message. The house has a landline, which they use, so I am curious if I could connect the controller to the physical landline phone? Or if I should use voip or google voice. I would probably plug the main controller into the outlet instead of battery power. I am not sure if the main controller is something that is feasible with just esp32/arduino or if it should be done with a raspberry pi.
Some main questions: is this feasible? What process makes sense for making a call (voip, landline, or something else)? is this an arduino or esp32 job? Is bluetooth the best way to connect the devices to the main controller? device and library suggestions
I have programming/technical experience just not a lot of arduino knowledge to properly understand the limitations. I would love any feedback and knowledge you can provide.
In this video, you will follow the process of designing my custom improved USB-C Digispark (Digistump) board, including the schematic and PCB design in Altium Develop, as well as how to flash the bootloader, configure the MCU fuse bits, and use the board.

Decided to document my workflow putting together this mini-project from scratch.
The video walks through the whole process: looking up the best project setups, calculating measurements on a water bottle, and then the fun part, wiring up the breadboard with an HC-SR04 ultrasonic sensor, a micro servo, some LEDs, a buzzer and lastly an LCD screen.
Everything is up, running, and successfully printing real-time distance values to the display!
I’m thinking about where to take this build next. What are some cool ideas or features you think I should expand this into?
Hello everyone! This is my Arduino project where I control an LED using simple electronic components. I would appreciate your feedback and suggestions to improve it. #Dar_Ibarmaja
I’ve been working on a miniature concert stage for my desk that displays the album art and song info for whatever I’m listening to.
Still a prototype, but it’s starting to come together and I’m pretty happy with how it’s turning out.
What would you add or change?
Hey everyone,
I wanted to share my latest project: a Bidirectional Visitor Counter using an Arduino. It's designed to automatically track people entering and exiting a room.
How it works:
Hardware: It uses an Arduino Uno, an I2C OLED display, and two IR proximity sensors placed about 30–50 cm apart.
The Logic:
If IR1 detects a person first, then IR2 detects them \rightarrow Count increases (+1 Entry).
If IR2 detects a person first, then IR1 detects them \rightarrow Count decreases (-1 Exit).
The live total is updated instantly and displayed on the OLED screen.
I've included my flow diagram and wiring layout in the image. Let me know what you think or if you have any questions about the code/logic!
