This week, I looked more into the induction charging.
Currently, the implementing induction charging could prove to be a challenge
since LiPo batteries, such as the one
that will power the motor, require special chargers. I have found some of these
LiPo battery chargers, but they sacrifice either voltage or current, making
them unsuitable for charging a 7.4 LiPo battery, the battery used last year.
More discussion must be held with my teammate before reaching a decision on the
motor.
Since last week, we have been trying to run the new brushless DC motor; however, it is still difficult to control, let alone its speed. Therefore, we had to pursue our alternative motor, the mini-stepper motor that runs at 5V. Found in Arduino starter kits, this mini-stepper motor is accompanied by its dedicated motor driver board, the ULN2003, which is a chip containing a series of Darlington pair transistors. An image of the stepper motor and the ULN2003 board is shown below: Sources: https://www.adafruit.com/product/858 https://www.amazon.com/gp/product/B01CP18J4A/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 We were able to successfully run the new mini-stepper motor with the sample code included with the Arduino starter kit. One benefit to using the sample code is that it utilizes the Stepper library’s functions. One use function is the setSpeed( ) function, which allows the user to set the RPM speed of the stepper motor. We found that the ma...
