This week we are waiting for our parts, ordered last week, to arrive. Meanwhile, we start to design the logic gates for the password system, the code to be implemented on the redboard and the electronic circuit. We change the 8-button password system to have 4 buttons to accommodate the limitation of the redboard. We add the specific type of the parts that we are going to use to our main page. Next week, if we have completed our design and received the parts, we will start to assemble the device.
