Single mos four-way control motherboard

Go directly to the code and test it. There is no explosion or fire. Note that this is the video received from the receiver. The first speed is about 1/4 of the full speed. Later, a better control motherboard will be released.  If you don’t have Arduino basics, don’t do it.
