I’m working on a heat and furnish monitor for our house. I am having problems with too few pins on my Arduino UNO, I know I can get a bigger one but maybe there are a smarter solution. i have following device hooked up.
Arduino UNO LCD keypad ( with 6 bottoms) 4- Relays running several DS18b20 on the onewire bus. 1. MAX 6675 (measure high temperature) 1. ENC28J60 ethernet chip.
now I’m missing 1-2 digital pins. I’ve noticed that the MSX 6675 and ENC28J60 both have pins named SO, CS and SCK.
if I understood it correctly I can’t use pin 0 and 1 if I have anything serial working at the same time.
is there any of my pins that can be combined in this setup, it doesn’t seem like much I have connected, taken into consideration that I’ve seen other people make robots doing lots of stuff with an Arduino.
