This project has three controlling switches, who's description are given following: - ================================================================= Switch || Name || Name on Diagram | ================================================================= Push Button || Up || X0 | Push Button || Stop || X4 | Push Button || Down || X2 | Sensor || Up sensor || X1 | Sensor || Down sensor || X3 | ================================================================= ================================================= Output || Name on Diagram | ================================================= Door moving UP || Y0 | Door moving Down || Y1 | ================================================= =============== Requirements:- =============== 1- Arduino Mega or UNO (code can be modified) 2- Three push buttons 3- Two diodes 4- Four relays 5- Gate opener motor 6- Two door sensors =========== Pin-outs:- ========================================================= Arduino || Hardware | ========================================================= 7 || Down sensor | 8 || Upper sensor | 9 || Stop button | 10 || Down button | 11 || Up button | 12 || +ve Terminal of 1st diode | 13 || +ve Terminal of 1st diode | +5v || Down sensor | +5v || Upper sensor | +5v || Stop button | +5v || Down button | +5v || Up button | GND || To relays | ========================================================== ====== Note: ====== 1- Author and revolutionbug will not be responsible in case of any mishap, damage or loss. 2- For RELAYS & MOTOR connections, please concern "diagram" figure attached with the project. 3- Up & Down sensors are gate switches which protects the motor from over current and shut down the system.
