Electric Gearbox Motor 12v
Motors need to be isolated from the AVR. This is because they
produce a high voltage spike when the current flow through them suddenly
changes. This can damage the digital circuitry in the microcontroller.
To separate the Gear-Box Motor from the microcontroller we used 4N35
optoisolators. Furthermore, ULN2003 drivers are used to supply the
motor's high current needs since the microcontroller has a maximum
current rating of 40mA. The drivers contain diodes to protect the
circuitry from high voltage spikes by directing the current through the
power supply.
The motor is controlled using an 8-step sequence to halve the rated
step angle. The step sequence rate is controlled via software. The 8
step sequence not only slows down the motor but also allows more
accurate positioning of the platform.
