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

  • Yeah getting I2C for LCD, but I don' think the gyro comes with one. Here's the link to it: gyro

I think you're fine depends on the gyroscope model and lcd. -For ultrasonic sensor thats 2 pins -the lcd needs at least 6pins but with an i2c adapter you only need 2 pins -3 push buttons 3 pins -one pin for the buzzer Plenty of room left on the uno
