![]() P2:Output keep OFF for time CL after get trigger signal and then output keep ON for time OP and then output will OFF.P1.3:Output keep ON for time OP after get trigger signal and then OFF Output will reset and stop timing if get trigger signal again during delay time OP.P1.2:Output keep ON for time OP after get trigger signal and then OFF Output will restart delay if get trigger signal again during delay time OP.P1.1:Output keep ON for time OP after get trigger signal and then OFF The input signal is invalid if get trigger signal again during delay time OP.After completing the circuit please upload the given code. We have an E-book on Arduino which contains 10+ projects on Arduino with detailed circuit diagrams and codes. RFID Sliding Door Lock Using Arduino|rfid project Password based door lock system using Arduino with Keypad RFID Lock System With Servo Using Arduino Please view more Tutorials on Arduino and Raspberry Pi. If you are facing any errors do tell us in the comments section below. We hope that you understand the project well. TECHATRONIC.COMĭigitalWrite(12,HIGH) // Normally ON Only For Chanies Relay Module NOTE: Please upload the code given below to the Arduino as it is. Also you cam make project with solenoid pump.Connect the positive wire of the solenoid lock with the Relay module.You have to connect the positive wire of the DC power supply to the other side of the Relay module and the negative wire to the solenoid lock as shown. ![]() Attach the Relay IN pin of the Relay module with the digital-12 pin of the Arduino as shown above.Join the GND pin of the Arduino to the GND pin of the Relay module.Connect the 5-volts pin of the Arduino to the VCC pin of the Relay module.You have to make the connections according to the circuit diagram given above. Unlike manual locks, a solenoid lock is more secure and you don’t need any key to open it as it works on electricity.Ĭircuit Diagram for the Project Connection Table Arduino UNO.The solenoid lock needs a 12-volts DC supply for its functioning so you have to provide it.You can use different sensors with it to make a high-security lock system. As the lock works with electricity so in case of power failure the lock can’t be opened or closed.you need to interface one relay also If you are not aware of the interfacing of the Relay module with Arduino then check it first. You can found these types of locks on the doors, safes, and cupboards nowadays.The lock is not directly connected with the Arduino instead of it we use a relay module. ![]()
