So you would like to build a motorized whiteboard that can be controlled from a smartphone? The iBoard is just the project you need to try. You can draw or erase the board and control all the action from your mobile device. You will need Arduino Uno, Raspberry Pi 3, Nema stepper motors, 1 servo, and a few other parts to complete this.
MircoSlepko has shared the instructions for this project here.
