create a Makefile in ~/kernel-programming containing:

#### start file #####
obj-m += hello1.o

all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
#### end file ####

and then run 'make' to build the module, 'sudo insmod hello1.ko', etc.
