Hello, i intent to make a project that will be using the following pieces:
1 x Arduino Leonardo
1 x Ethernet shield
2 x rfid rc522 card readers
1 x 4 relay module
1 photocell (gate photocell presence detector)
1x display with 4 pins (vcc gnd sda scl)
Can i plug it all to an Arduino Leonardo?
Or do i need something more?
The code i have until now and the design of the project is in GitHub at GitHub - BrixSat/Parking-Gate: Arduino parking gate controller
Any help is always appreciated.
Thanks in advance for your help.
