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



Intro :

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 :

Mounting Parts

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.

Using a piece of paper trace the mounting holes for your dead bolt and transfer them onto your acrylic sheet. Since most dead bolts are going to be slightly different I am not sharing the template I made out of a piece of paper (mainly because it isn't anything worth sharing).

Leave the paper covering on while working with the acrylic. The paper makes it easy to mark where to cut/drill as well as protects the material from scratches. Once all of your cuts are made and your holes are drilled you can start installing components such as LEDs and switches.

Step 2:


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.

At some point the wires to my servo had been cut so I had to open the case and solder on new ones. I took that opportunity to solder on a second wire to the 5v line and connected it to the limit switch arm.

Step 3:


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.
