DC Motor Driver and PWM Driver

The project creates a DC motor driver board that will control 2 small DC motors while the PSM driver board will control 3 channels of PWM at up to 5A each.

Two small DC motors are being controlled individually by the DC motor driver board where each motor can be driven at a maximum of 750mA. The risk of blowing out the motor driver L293D may occur if a motor that draws more current than 750mA is wired up. Both direction and speed control is supported and it is designed to be interfaced with a microcontroller such as the Arduino. Since it has a simple and easy to use interface, any microcontroller chosen should be able to work with this board. The logic chip 74HC00N has 14 pins and fit into the smaller socket.

The PWM board is designed to allow the control of high power devices that only have a single polarity. It can be used for heaters, fans, solenoids, and even motors but in only one direction. PWM input is taken from a microcontroller such as Arduino and amplifies them into high power outputs, then drives 3 channels with heatsinks.
