Kit No: RT382 433MHz
Connect with arduino :
A.Momentary ----all disconnect (defult) ;
B. Toggle ---- connect T ;
C.Latch ---- connect L ;
1: This is a simple wireless remote control module, no additional instructions.
2 : VT output high (5V TTL level) when signal received;
3: D1 D2 D3 D4 four data pins corresponding to four buttons on the remote control, for example: when the A button on the remote control is pressed, D1 high output, etc.
4: VT and D1-4 pins are 5V TTL pin 10MA maximum energy output current can drive the MCU port or LED lights .
Inter-locking (Latch): 4-way relay each other to switch, when relay A is working and locked , relay B C D corresponding to switch off; when B is working and locked , corresponding relay A C D swith off ; Only 1 relay is on among 4 relays A B C D;
Non-locking type (Momentary): Press A and hold it , then A is on.Same as Relay B C D ;Self-lock type (Toggle): 4 chanels opens and closes independently, 4 chanels can work together ,they don’t affect each other . press A button, A relay of work and locked, press again then disconnected; Same as B C D .
User guide :
1: Learing ID : Press learning button , LED is on and beginning to learn ;after learning , LED will flash for a while .Then LED will keep being on to learn the next remote. If perss the learned remoter controller , auto-quit learning within 10 seconds;
2: Delete ID : Keep pressing learning button for 5 seconds , LED will be on and enter deleting . LED off means finishing deleting;
3: Antenna with a soft wire or other hard metals (such as whip antenna), try to straighten. Do not go near metal objects;
4: Power supply voltage requires stable and low ripple factor, multi-level filtering (such as adding beads, inductors, capacitors, etc.);

Keyfob Deadbolt with Arduino uno R3 and RF transmitter and receiver
The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn't an option, but eliminating the need to use a key was.
Step 1 :
I used a couple of pieces of acrylic that I acquired in the dumpster of the plastic shop next to my place of work (they throw out alot of small pieces like this). Alternatively another material could be used if you don't have access to acrylic, but it is easy to work with and looks cool.
I used an old parallax servo I had in my parts bin. This small servo is more than strong enough to turn the deadbolt. In order to attach the servo to the lock shaft I used epoxy putty. Epoxy putty is very easy to use and is extremely versatile. The wire you see sticking out of the putty will be used as the arm for the limit switch.
Screws were countersunk from the back of the acrylic. A wire was attached to each screw and then to a digital pin on the Arduino. When the wiper with the 5v wire touches the screw it pulls the digital pin high on the Arduino. Please see the schematic for further details.
Step 4: Program
Disclaimer: I am not a programmer and therefore the below code may not be the most efficient. Feel free to improve the code for your own uses if you see any errors or problems. It works for me so I hope it works for you.
