Attiny85 ADC Pin besides PB3

Other Hardware Sensors
1

Hi,
I try to connect RF433, LCD(I2C) and Soil moisture sensor to Attiny85.

I can't get RF433 working beside PB3(Pin3) and also my analog soil sensor only work with this pin otherwise it'll read only 0/1. PB0 and PB2 for i2c lcd.

Thanks;

Pin 3 is the only pin where the ADC3 is on Pin3
ADC1 is on pin PB2
ADC2 is on pin PB4

ADC0 is on the reset pin, so you cant use that, unless you disable it as reset pin.

PB0 and PB1 have no connection to the Analog to Digital Converter

It seems like the board is not suitable for the project.
