1. The assignment for this week was to automate a machine assembled in a previous class using stepper motor drivers and an Arduino board. 2. Students worked to connect the motor drivers and test the motors while installing software to control the machine automatically. 3. The document discusses several student projects, including automating a loom using micro servos controlled by a microcontroller programmed in C.

7. Conclusions.
1. The construction of the card with the microcontroller and the light sensor is
simple, however because we weld the parts. All information take it from the
Fab
tutorials
2. The second part is complicated by the programming of the microcontroller,
which was displayed not bar recognition of the sensor in your computer monitor.
3. By now the task is in progress.
