I’m following the circuit below to hook up my 8x8 bicolor LED matrix. So far, I am certain that I hooked up the matrix correctly but I’m not sure if I’m using the right resistor.
Right now, the LED will light up and only display the pattern below, if I try to upload any other patterns it will not change. Also the LEDs which are supposed to be red are showing up as orange at the moment. I’m using a 10uF and .1uF capacitor. I’m currently using a 33k ohm resistor to connect pin 18 to 5V power. (this a guess since I don’t know the forward voltage or amplitude of the matrix. I’m using an LED matrix from this site: https://www.creatroninc.com/product/8x8-led-matrix-20mm/).
Any assistance would be much appreciated!
