Let's build it!
In order to build the programmable DC motor controller, follow the following steps:
- Wire the programmable DC motor controller with the LCD circuit on a solderless breadboard, as shown in the previous image as well as the circuit's schematic diagram that is shown in the next image.
- Upload the software of the programmable motor controller to the Arduino by using the sketch shown next.
- Close both the Program and Enables switches. The motor will spin.
- When you open the Enable switch, the motor stops.
The LCD message tells you how one can set the Program switch for an ON and OFF motor control. The Program switch allows you to select between the ON and OFF motor control functions. With the Program switch closed, toggling the Enable switch will turn the motor ON and OFF. Opening the Program switch will prevent the motor from turning on. The next few sections will explain additional details on the I/O interfacing of discrete digital logic circuits and a small DC motor that...
