Smart Home based on Raspberry Pi

A few days ago I saw that some refrigerators come with touchable panels on them, so I thought I could also use my own touch screen DIY touchable smart refrigerator project. I saw that many smart homes are done with Raspberry Pi, and I have a Raspberry Pi pico board. So I designed it out. 冰箱界面1.jpg 冰...

Re: LCD and Gyroscope

But now I have a new problem, I've never made a 3D model before and I'm not sure what kind of image format the 3D model is in. My LCD can support jpg, bmp, png, svg and gif.

Re: Seeking the suitable robotic arm

I finally purchased a 6-axis robotic arm and I've started the first steps to make it do simple grabbing things.
I control the robot arm to grasp objects by tapping the directional buttons on the touch screen as well as grasp button.

My current situation is like this, the C++ program produces an array, I want to put this array into python to do some operations, and then the data after python processing is returned to the C++ program to continue processing.
How do I do this?

Re: LCD and Gyroscope

You are right, what I mean is that a 3D model is displayed on the LCD, and the viewer can drag and drop the model with his finger to achieve multi-angle viewing. Inspired by the everyday use of cell phones, when we look at an object that can be rotated, we can use our fingers to rotate it. The scree...

Seeking the suitable robotic arm

I'm recently interested in robots and robotic arms, and I'm looking for a robotic arm that can communicate with my touch screen through UART. I have designed the GUI interface. By the way, should I choose a 3-axis robotic arm or a 6-axis robotic arm?

Re: Can lithium batteries be recharged?

Ok, I will not charge it and I will buy a new replacement if necessary. But I think it could work for a long time.

Seeking tips about card readers

I read an article about card reading a few days ago, but I don't understand how it works. Suppose I want to make a project that can store, read and unlock a card, what do I need to prepare?
