The suspended solar motor turns when exposed to light. It's so fun. [Copy link]

Foreigners really know how to play. Not only does it rotate when exposed to light, but it also levitates magnetically. Everyone, what kind of black technology is this?

There is no suspension, but there are bearings.

The rotation when seeing light is seen, but the suspension is not felt. The rotation when seeing light is the conversion of light energy into electrical energy. The principle is very simple. The motor can power the rotation.

The nRF24L01 wireless transmission module can achieve one-to-many, many-to-one, and many-to-many. According to the characteristics of the nRF24L01 chip, it can achieve that the data will not affect each other when multiple devices are running at the same time. This involves the pairing problem. When I did this, I thought of changing the receiving and sending addresses in real time. This method is indeed usable, especially in one-to-many situations, but it is not very good in many-to-one situations, and there will be data loss. Therefore, for many-to-one, it is recommended to use multi-channel receiving data, and combined with my method, I believe it can be solved. I didn't do that part. If someone has done it, I hope you can share it for learning. After all, OPEN SOURCE is a good method.
