i'm new to the scene of microcontrollers, i thought of using RasPi for my project, but lastly i think one Arduino would be the best choice.
So, i will be using the following components in my project, and i don't know if the Arduino Uno will be enough, and if that's true, should i pick the Mega?
The modules in italic
are for future versions of my project. But have to keep on mind that i will need space/pins for those.
The Easy Driver with one stepper
One i2c (dedicated IIC bus control) and to it connected one LCD AMC2004A?
Temperature sensor (DS18B20)
One i2c interface for pH measuring (here
One SSR relay module board (here
)One Ultrasonic module sensor (HC-SR04)One humidity&Temperature sensor (DHT11)2 Led as indicatorsOne or two buttons
Thank you for your clarifications, hope you can help me out here!
