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?

LCD and Gyroscope

I am using Stone's LCD if the LCD itself does not come with a gyroscope, but I want to accomplish some functions like being able to rotate 360° to view a model on the LCD. Suppose I connect an external microcontroller and an MPU6050 module, is it possible to achieve this function?

C++ how to wait for input at runtime

Normally with getchar and scanf, etc., the program will stop and wait for input. How can I run other functions while waiting for user input?

I will probably only use an 8" or 10" screen and already have options. You want to use a very large size touch screen might be a big cha...
