Basic Arduino example code to control a stepper motor 

Basic Arduino example code to control a stepper motor 

Now that you have wired up the digital stepper motor driver
and set the current limit, it is time to connect the Arduino to the computer and upload some code. You can upload the following example code to your Arduino using the Arduino IDE. For this specific example you do not need to install any libraries.

This sketch controls both the speed, the number of revolutions and the spinning direction of the stepper motor.

You can open the code in a new window by clicking on the button in the top right corner.

  1. /*Example sketch to control a stepper motor with A4988 stepper motor driver and Arduino without a library. More info: https://www.makerguides.com */
  3. // Define stepper motor connections and steps per revolution:
  4. #define dirPin 2
  5. #define stepPin 3
  6. #define stepsPerRevolution 200
  8. void setup() {
  9. // Declare pins as output:
  10. pinMode(stepPin, OUTPUT);
  11. pinMode(dirPin, OUTPUT);
  12. }
  14. void loop() {
  15. // Set the spinning direction clockwise:
  16. digitalWrite(dirPin, HIGH);
  18. // Spin the stepper motor 1 revolution slowly:
  19. for (int i = 0; i < stepsPerRevolution; i++) {
  20. // These four lines result in 1 step:
  21. digitalWrite(stepPin, HIGH);
  22. delayMicroseconds(2000);
  23. digitalWrite(stepPin, LOW);
  24. delayMicroseconds(2000);
  25. }
  27. delay(1000);
  29. // Set the spinning direction counterclockwise:
  30. digitalWrite(dirPin, LOW);
  32. // Spin the stepper motor 1 revolution quickly:
  33. for (int i = 0; i < stepsPerRevolution; i++) {
  34. // These four lines result in 1 step:
  35. digitalWrite(stepPin, HIGH);
  36. delayMicroseconds(1000);
  37. digitalWrite(stepPin, LOW);
  38. delayMicroseconds(1000);
  39. }
  41. delay(1000);
  43. // Set the spinning direction clockwise:
  44. digitalWrite(dirPin, HIGH);
  46. // Spin the stepper motor 5 revolutions fast:
  47. for (int i = 0; i < 5 * stepsPerRevolution; i++) {
  48. // These four lines result in 1 step:
  49. digitalWrite(stepPin, HIGH);
  50. delayMicroseconds(500);
  51. digitalWrite(stepPin, LOW);
  52. delayMicroseconds(500);
  53. }
  55. delay(1000);
  57. // Set the spinning direction counterclockwise:
  58. digitalWrite(dirPin, LOW);
  60. //Spin the stepper motor 5 revolutions fast:
  61. for (int i = 0; i < 5 * stepsPerRevolution; i++) {
  62. // These four lines result in 1 step:
  63. digitalWrite(stepPin, HIGH);
  64. delayMicroseconds(500);
  65. digitalWrite(stepPin, LOW);
  66. delayMicroseconds(500);
  67. }
  69. delay(1000);
  70. }

How the code works: 

The sketch starts with defining the step and direction pins. I connected them to Arduino pin 3 and 2.

The statement #define is used to give a name to a constant value. The compiler will replace any references to this constant with the defined value when the the program is compiled. So everywhere you mention dirPin, the compiler will replace it with the value 2 when the program is compiled.

I also defined a stepsPerRevolution constant. Because I set the driver to full step mode I set it to 200 steps per revolution. Change this value if your setup is different.

  1. // Define stepper motor connections and steps per revolution:
  2. #define dirPin 2
  3. #define stepPin 3
  4. #define stepsPerRevolution 200

In the setup() section of the code, all the motor control pins are declared as digital OUTPUT with the function pinMode().

  1. void setup() {
  2. // Declare pins as output:
  3. pinMode(stepPin, OUTPUT);
  4. pinMode(dirPin, OUTPUT);
  5. }

In the loop() section of the code, we let the motor spin one revolution slowly in the CW direction and one revolution quickly in the CCW direction. Next we let the motor spin 5 revolutions in each directions with a high speed. So how do you control the speed, spinning direction and number of revolutions?

  1. // Set the spinning direction clockwise:
  2. digitalWrite(dirPin, HIGH);
  4. // Spin the stepper motor 1 revolution slowly:
  5. for(int i = 0; i < stepsPerRevolution; i++)
  6. {
  7. // These four lines result in 1 step:
  8. digitalWrite(stepPin, HIGH);
  9. delayMicroseconds(2000);
  10. digitalWrite(stepPin, LOW);
  11. delayMicroseconds(2000);
  12. }

Control spinning direction: 

To control the spinning direction of the stepper motor we set the DIR (direction) pin either HIGH or LOW. For this we use the function digitalWrite(). Depending on how you connected the stepper motor, setting the DIR pin high will let the motor turn CW or CCW.

Control number of steps or revolutions: 

In this example sketch, the for loops control the number of steps the stepper motor will take. The code within the for loop results in 1 step of the stepper motor. Because the code in the loop is executed 200 times (stepsPerRevolution), this results in 1 revolution. In the last two loops, the code within the for loop is executed 1000 times, which results in 1000 steps or 5 revolutions.

Note that you can change the second term in the for loop to whatever number of steps you want. for(int i = 0; i < 100; i++) would result in 100 steps, or half a revolution. nema 23 gearbox

Control speed: 

The speed of the stepper motor is determined by the frequency of the pulses we send to the STEP pin. The higher the frequency, the faster the motor runs. You can control the frequency of the pulses by changing delayMicroseconds() in the code. The shorter the delay, the higher the frequency, the faster the motor runs.

La pieza de mano que cambio mi vida

Recuerdo ese aterrador ruido que escuche cuando era niño, aun hoy en día puedo sentir esa sensación que causaba en mí. Mi primera memoria de un consultorio dental es la sala de espera y ese estridente sonido que causaba la pieza de mano, claro que hasta aquel entonces no sabía qué clase de artefacto podía producir tan horrible ruido. Rápidamente descubrí que se trataba, algo que nunca había visto, mi curiosidad reemplazo mi miedo y luego mi curiosidad se convirtió en el incontrolable deseo de tener una para mí solo. Así, ese mismo día, me hice la promesa de que algún día yo sería un dentista.


Pieza de mano antigua pero confiable

Mi primera pieza de mano odontologia era nueva pero un modelo antiguo concentrix II de los años 80, rápida, poderosa y ruidosa. No era tan estilizada y moderna como la de muchos de mis compañeros de clase y todos me jugaban bromas debido a ella, pero cuando se trataba de hacer preparaciones en dientes, especialmente en metal, siempre se desempeño de maravilla.
Una revisión breve de las piezas de mano. Desde los antiguos taladros dentales hasta las piezas de mano de alta velocidad.

Las piezas de mano dentales han evolucionado durante los años (1). Un viejo profesor de mi universidad me solía contar sobre los viejos tiempos de la odontología. Cuando él era estudiante, me contaba, aprendió la profesión con esos viejos taladros dentales potenciados con una correa de cuero. Era terrible para los pacientes, handpiece 2decía, la vibración y el ruido hacían de la consulta una experiencia poco placentera.

Cuando las piezas de mano con turbina de aire aparecieron en la escena dental, el ruido se convirtió en un verdadero problema, ya que las piezas de mano de alta velocidad pueden producir entre 65 hasta 75 decibeles y cuando se trata de daño al oído, llegar a 90 decibeles se considera que puede causar daño permanente en la capacidad auditiva

(2). Quizás te ahorre dinero pero con el tiempo tus costos de salud se incrementaran.

Además, tienes que considerar el ruido incrementa los niveles de estrés en los pacientes más jóvenes y pueden hacer que sean poco cooperativos y si hablamos de tecnología que mal gasta el tiempo, realmente creo que una pieza de mano ruidosa se debe considerar como tal.

Gracias a los nuevos avances en tecnología dental, ahora tenemos las turbinas eléctricas con rodajes cerámicos que reducen el ruido hasta en un 15%, con mayor poder, control de torque y tamaños reducidos de cabezal para mejorar la visibilidad del campo operatorio. Las nuevas piezas de mano de última generación son sin lugar a dudas una buena inversión para el consultorio dental que tiene muchos beneficios que pueden disfrutar los pacientes y los odontólogos.(pieza de mano recta)

lámparas halógenas de polimerizacion dental

Que tener en cuenta al comprar una lampara de fotopolimerizacion dental

Años atrás y no muchos la cosa era bastante mas simple: era nada más lámparas halógenas de polimerizacion dental con algún que otro programa y listo.

En estos días pareciera que comprar una lámpara de polimerización dental requiere tener toda una instrucción previa dada la cantidad de información que los vendedores nos dan ( y muchas veces innecesaria) que no hace más que confundirnos.

Lampara de polimerización dental: Detalles
Veamos:

Las lampara de polimerización dental de elección al día de hoy son las lamparas de polimerización dental de Led, que han ampliamente superado por su tecnología a las hálogenas.

Sin intentar redundar en detalles ya a esta altura conocidos, entre otras cosas por la larga duración de la lámpara ya hacen una diferencia más que importante.

Cuando estas nuevas lamparas de polimerización dental de Led aparecieron, se le decia al odontologo que tenga cuidado cual compraba porque según la marca de elemento a fotopolimerizar podía o no hacerlo dado que la longitud de onda que salía podían escapar al rango de activación que poseía el producto y entonces no funcionarle.

Eso fue rápidamente superado y hoy ese problema ya no existe.

Otros elementos que podemos tener en cuenta van según gustos del operador, a saber:
