b$.$ A Sensor Based Paper Towel Dispenser control system will be designed with the STM$32$F$401$ processor. There are $2$ inputs and $2$ outputs. Inputs are sensor input nad Towel paper run out input and Outputs are Motor drive output and Towel paper run out warning LED.System will work as follows. When $1$ is detected from the sensor input, the paper feeding motor will be started and stopped after $3$ seconds. If there is no paper, $1$ will come from the Towel paper run out input. In this case, the engine will not be started and the warning light will be set on and the warning light will remain on until the towel paper is renewed.Suggest that all the settings regarding the input and output of the ports have been made previosly. Write the required software in C language within the Superloop $($while $(1)).$You can use the Delay$($int Delay$\_$ms$)$ function for creating delays. $($SLO$2)20$p$)$STM$32$F$401$Sensor InputPCQGPIOCPAOMotor Drive Out $1$: Start, $0$: StopTowel paper run out input PC$1$GPIOAPA$1$ Towel paper run out warning LEDAnswer:
