Week 4
Week 4 26/02/2023 In week 4, the details of the circuit were completely worked out. This week was mainly devoted to the assembly and debugging of the circuit and housing parts. Accomplishments : 1、The problem that the motor could not run in the circuit last week was solved by adjusting the position of the BJT in the circuit. 2、Used the acrylic board to complete the production of the shell of the dealer. 3、The normal operation of the overall dealer was achieved without putting playing cards. Problems and alternatives : In the final stage, replacing the computer connection with a lighter battery would give the device a better look. After replacing the computer USB power supply with a 9V battery, the designers found that the 9V battery could not provide enough voltage to the servo motor in the circuit. Then, the team members discussed and made some assumptions to adjust the structure of the housing, so that the computer USB can provide power while ensuring...
