Its my first project with an Arduino, so please bear with the dumb questions.
For this project of mine, I need an Ultrasonic Sensor, a Gyroscope, a Buzzer, three push buttons and an 16x2 LCD.
Can I connect all these components at once to an Arduino Uno? I mean will I run out of pins or not? Should I go for a Mega 2560 (will have to buy one though).
Edit: a GSM sim800 as well lol
