====== Marca Led Negativo ====== {{:informatica:arduino:marca_led.png?100|}} Hay que poner una resistencia de unos 330mA si lo conectamos a 5V Así se enciende directamente: {{:informatica:arduino:led_01.png|}} Para calcular la resistencia exacta, primero calculamos el voltaje del led poniendo un polimetro en paralelo: {{:informatica:arduino:led_02.png|}} Si en vez de 5V ponemos una pila de 9V por ejemplo, ponemos una reistencia de 900Ω por si acaso. En mi caso me da un led rojo 1,9v y uno azul 3v ====== Paneles led ====== http://www.minitronica.com/producto/matriz-led-de-8x8-con-max7219/ http://tienda.bricogeek.com/componentes/124-matriz-de-led-r-g-mediana-con-interfaz-serie.html https://www.sparkfun.com/products/11861 http://www.dx.com/es/p/1-8-8x8-seamless-cascadable-red-led-matrix-display-module-with-spi-interface-for-arduino-408734 ====== MAX7219 Matrix 8x32 ====== Este funciona: https://microcontrollerslab.com/led-dot-matrix-display-esp32-max7219/ Aquí hay ejemplos sin probar: https://www.circuitgeeks.com/arduino-max7219-led-matrix-display/ ====== MAX7219 Matrix 8x8 ====== Minitutorial:\\ http://www.prometec.net/scroll-max7219/ Nos descargamos la biblioteca, que no librería, de aquí: https://code.google.com/archive/p/arudino-maxmatrix-library/downloads Desde el IDE de arduino, en sketch, import library la añadimos.
