| # Componentes necesarios | ||
|
|
||
| - Arduino (Cualquier modelo compatible). | ||
| - x2 Servomotor. | ||
| - Análogico de joystick. | ||
| - Cables jumpers, macho macho y macho hembra (en este caso puede variar la cantidad de cables a utilizar dependiendo del cuidado al llevar a cabo en el circuito). | ||

| # Código desarrollado | ||
|
|
||
| El proyecto consiste en realizar la configuración de un joystick para posteriormente hacer uso de dos servomotres enlazados entre si para poder controlar un servomotor cunado el joystick se mueva en el eje X y otro servomotor para cuando el joystick se mueva en el eje Y, de esta manera lograriamos un completo rango de movimiento con un "brazo robot" (Dos servomotores enlazados) que en la puntan podrían tener un lazer a gusto. | ||

| # Used pines | ||
| int joystickXPin = A0; | ||

| int joystickSwPin = 2; | ||
| int servoXPin = 12; | ||
| int servoYPin = 13; | ||
|

| # Vars to analog values from joystick (X and Y) and vars to save the angles for servos | ||
| float joystickXVal, joystickYVal, servoXAngle, servoYAngle; | ||
