The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presence detection.

copilot Entiendo que deseas diseñar un oscilador utilizando el chip 555. Aquí están algunos pasos que puedes seguir para hacer esto. Conecta el pin 1 (GND) del IC 555 a la terminal negativa de tu fuente de alimentación (0V). Conecta el pin 8 (VCC) del IC 555 a la terminal positiva de tu fuente de alimentación (11V). Conecta la resistencia de 10kΩ (R1) entre el pin 8 (VCC) y el pin 7 (DISCHARGE) del 555. Conecta tu potenciómetro de 100kΩ (R2) entre el pin 7 (DISCHARGE) y el pin 6 (THRESHOLD) del 555. Junta los pines 2 (TRIGGER) y 6 (THRESHOLD) juntos y conecta los pines unidos al lado negativo de tu condensador de 10nF (C). Conecta el lado positivo del condensador de 10nF (C) a VCC (el pin 8). Conecta el pin 4 (RESET) al VCC si no quieres usar la función de reset. De lo contrario, puedes conectar una señal de reset aquí. Conecta el pin 3 (OUTPUT) del 555 al terminal positivo de tu resistencia de 470Ω. Conecta el otro terminal de la resistencia a tierra. El condensador de 10uF debe estar conectado en paralelo a la alimentación (entre VCC y GND) para suavizar cualquier ruido en la fuente de alimentación de 11V. Te sugiero que experimentes con el valor del potenciómetro (R2) hasta que consigas el Duty Cycle deseado. Por lo general, es posible cambiar la frecuencia del pulso y ajustar el Duty Cycle utilizando este control. Si, después de realizar estas conexiones y ajustes, aún no puedes obtener el Duty Cycle deseado, podría ser indicativo de que los valores de resistencia y condensador que tienes no son adecuados para tu rango de frecuencia y Duty Cycle objetivo. Para que obtengamos un Duty Cycle del 75%, necesitamos usar el chip 555 en modo astable y debemos calcular los valores de R1 y R2 (resistencia total de carga y descarga respectivamente) que nos ayude a conseguir esto. El tiempo de alta (T_high) y el tiempo de baja del ciclo (T_low) de la oscilación salen determinados por R1, R2, y C (el condensador). Se pueden usar las siguientes fórmulas para calcularlos: T_high = 0.693 * (R1 + R2) * C T_low = 0.693 * R2 * C Duty cycle = ( T_high ) / ( T_high + T_low ) Para un Duty Cycle de 0.75: Estableceremos R1 como la resistencia de 10 kilohmios que se proporcionó. Con el potenciómetro de 100 kilohmios como R2, podemos variarlo para ajustar el Duty Cycle según necesitemos hasta que se llegue a la relación deseada. Considerando que el condensador C es el condensador de 10 nF que se proporcionó, anteriores declaraciones son bajo supuesto que el tiempo de operación (T = T_high + T_low) caiga en un rango aceptable. Para el esquemático: Conecta VCC de tu 555 al terminal positivo de tu fuente de voltaje de 11V y GND a tierra. Conecta los pines 2 (TRIGGER) y 6 (THRESHOLD) juntos y al lado negativo de tu condensador de 10nF. Conecta el lado positivo del condensador a VCC. Conecta el pin 3 (OUTPUT) al terminal positivo de tu resistencia de 470 ohmios. Conecta el otro terminal de la resistencia a tierra. Conecta tu resistencia de 10 kilohmios entre VCC y los pines 2 y 6 del 555. Finalmente, conecta tu potenciómetro entre los pines 2 y 6 y el pin 7 (DISCHARGE) del 555. El condensador de 10uF debería estar conectado en paralelo a la alimentación para suavizar cualquier ruido en la alimentación de 11V. Estas son mis suposiciones y pasos sugeridos pero recuerda variar el potenciómetro hasta conseguir el Duty Cycle deseado en caso de no conseguirlo de forma inmediata. Si por alguna razón no puedes conseguir el Duty Cycle de 75%, es posible que las resistencias y condensadores proporcionados no sean los adecuados para el rango de frecuencia y Duty Cycle deseados. En tal caso, puede que tengas que utilizar otros valores de componentes.
