Hello! Right now, I'm working on a project and wondering if all of my devices can be connected to my UNO. I'm not sure how many devices I can connect.
I'm hoping to connect:
2x ultrasonic sensors
2x mini H-Bridges each with their own motor
2x separate LED's
Does this seem possible? Thank you!
Yeah - the motors will likely need a separate power supply (motors usually draw too much current, and even small ones that don't often put noise on the power supply that can trigger resets), but there's plenty of info on this around.
The limits are current you're pulling off the power pins, the number of IO pins you have, and the peripherals (if any - stuff like timers, serial ports, ADC channels, etc) you're planning to use. You need like... 10 pins by my count, so you've got plenty of headroom, and none of those components (except maybe the ultrasonic sensors) require any peripherals; not sure if ultrasonic sensor libraries use a timer (I suspect it's a case of some-do-some-dont)
