Arduino MAJOR PROJECT

Hi, Im completing a major project for school and I need help on few key aspects on it's functionality. How can I make my stepper motor have more torque when spinning the blind and how can I time the motor to be set in a scheduled time, as the sprocket will be connected with the chain of the blinds, so when you wake up the blinds rise and when its night it'll lower the blinds. The top piece above the motor is the Arduino uno 3, the problem with this I need to always connect it with the computer to upload the code, are there any models that'll help so I can plug it in without the use of always connecting it and how can I do this without using a bread board. Ps: I am making a case for the Arduino project to make it more presentable and the part I sketched is already 3D printed Image
