Hi All,
I have been working on an Incubator for my chickens and quail to grow my skills with raspberry pi & Arduino.
I had a few issues with faulty parts from China which slowed the process but am now back on track.
Im running a Raspberry Pi 3B which is sending Temperature and humidity readings to the web via Node-Red dashboard. This is working very well.
I want to add a 3.5 inch touch screen however it will use the same gpio pins that my dht22 sensor is currently using.
What is the work around for this? I'm running Buster operating system and using 3.3v pin, gnd & pin 4 for the sensor.
I have also got an Arduino Uno controlling a 28BJY48 stepper motor for the automatic egg turner.
Ill soon be adding a mosfet to control the speed of the fan depending on how high the temperature and humidity levels are.
It's been a challenging project and I'm learning what components not to use as much as which components I can use.
Any assistance with the screen and gpio pins would be appreciated.
Thanks
