**Building a Mechanical Arm to Turn Your Deadbolt Door Lock**

The first step in building this project is to create the mechanical arm that will turn the lock. This can be thought of as a robot replacement for a bouncer, and it will be made entirely out of popsicle sticks. To build the mechanical arm, you can use hot glue and paper clips or if you have a drill like the author does, nuts and bolts. The author provides photos of their popsicle art construction and explains how it is constructed.

The mechanical arm will need to turn around a deadbolt door lock, and for this purpose, we need something to control the mechanical arm. We are going to build a circuit that can tell the difference between different kinds of knocks. To make this work, we will need some components such as resistors, capacitors, and a crystal oscillator. The author notes that while these components may seem like a lot, it is not a hard build and they will be explained in full detail later on.

The circuit will also require an 18 Mega 8 micro controller and an LM 358 op-amp, which are the brains of the operation. The op-amp is what will hear the knocks and allow the door to lock or unlock. Once the circuit is complete, we can install the two chips: the 80 Mega 8 microcontroller and the LM 358 op-amp chip. Make sure all those legs are straight and push it in place.

To make a base for our electronics, we will use some hot glue and put together two sticks, gluing our circuit board to that. We will do the same on the other side. Next, we need to mount our servo motor, which is what will actually turn our mechanical arm. This is done by hot gluing it in place and also for added security, taking some copper wire and running it around the ends of the servomotor and around the popsicle sticks and hot gluing them all together.

Now that we have our circuit complete, we can give it power and test it out with three knocks. As you can see from the video, our circuit is working perfectly. The mechanical arm is able to turn the lock and open and close the door on command.

**Materials Needed**

The materials needed for this project are quite affordable and can be purchased for less than 20 dollars. These include popsicle sticks, hot glue, paper clips, nuts and bolts, resistors, capacitors, a crystal oscillator, an 18 Mega 8 micro controller, an LM 358 op-amp, a servo motor, a keypad, and additional components such as a piezoelectric sensor.

**Kits Available**

For those who want to build this project but don't feel comfortable doing it themselves, there are kits available that include all the necessary parts and instructions. The basic kit comes with a mini servo that can exert up to three kilogram force of centimeters of torque, an ultra sensitive piezoelectric sensor that will detect knocks, taps, kicks, and licks of all kinds, and a pre-programmed micro controller that opens with three knocks.

The premium kit also includes a BP servo that can exert three times more force than the basic kit, parts for a keypad, and other additional components. Both kits are available at an affordable price, starting at 10 dollars, and come with access to the author's free online learning portal, which includes full in-depth online tutorials, HD video, and photos, as well as a forum where you can ask other members for help and share your build.

**Conclusion**

Building this mechanical arm project is a fun and rewarding experience that can be completed at home with minimal equipment. The parts are affordable and the instructions are easy to follow, making it perfect for beginners and experienced builders alike.

using popsicle sticks for part of this build oh and the code is easy to change if the knock ever falls into the wrong hands now here are all the materials we'll need for the project and I'll show you where you can get all of these for less than 20 bucks later on in the video the first thing we need to build is the mechanical arm that turns the lock now you can think of it as your robot replacement for a bouncer and we're going to make it all with those popsicle sticks you can use hot glue and paper clips or if you have a drill like I do nuts and bolts and this is a little bit better popsicle art than you probably made in preschool just take a look at some of these shots and you can see basically how it's constructed and it'll fit around your deadbolt door lock now we need something to turn this mechanical popsicle arm and we're going to be building a circuit that will control that it's a pretty easy circuit that can tell the difference between different kinds of knocks so you make sure you have it programmed for the knock you want the brains of the organization will be an 18 mega 8 micro controller and an LM 358 op-amp but we're going to need some other components to make it all work together like resistors and capacitors and a crystal oscillator quite a few components but again this is not a hard build and I'm not going to take you through step-by-step of how to do it but I will make the schematic available for you for free on Kipkay calm the Paizo element is one component and that's what's going to hear the knocks and allow the door to lock or unlock now once the circuit is done the last thing to do is install the two chips the 80 mega 8 microcontroller make sure all those legs are straight and push it in place and then also the LM 358 op-amp chip okay now we're going to need some hot glue and some more popsicle sticks because we need to make a base for our electronics so be using some hot glue we'll put two sticks together and glue our circuit board to that and do the same on the other side now it's time to mount our servo motor this is what's going to actually turn our mechanical arm so we'll hot glue that in place and then also for some added security I took some copper wire and ran it around the ends of the servomotor and around the popsicle sticks and hot glued it all together okay giving it some power and some knocks and you can see our circuit is working now in order to connect the mechanical arm to the servo we need a servo connector that comes with it so we're going to superglue that in place all right I've mounted the mechanical arm to my deadbolt and I velcroed my electronics right above that and gave it power it's time to test it out with three knocks it works like a charm and don't forget that knot can be changed to any combination you want okay now you want to know how to get all this stuff and build your own it's simple the basic kit comes with a mini servo which will pull upwards of three kilogram force of centimeters of torque what that means is it can turn most loose dead bolts with ease the kit features an ultra sensitive piezoelectric sensor that will detect knocks taps kicks and licks of all kinds included is the micro controller that's pre-programmed to open with three knocks no programming required now if you want to take this project up a notch you can get the premium kit it features a BP servo that can exert three times more force which can turn even the toughest of deadbolts included in the kit is the piezoelectric sensor but also parts for a keypad so you can choose which opening mechanism you'd want to install and just like the beginner kit the keypad is pre-programmed but both are reprogrammable now if you want to build this kit you can definitely grab the schematics and buy the parts yourself the parts will set you back about 40 bucks but as a convenience for my faithful fans I've turned it into a kit and made it available at a super affordable price that starts at 10 bucks all the kits come with access to my free online learning portal with full in-depth online tutorials with HD video and photos as well as a forum where you can ask other members for help and share your build plus a live chat every month with me Kipkay check out both of these kits by heading to kit cake it's calm there's also a link in the description of this video this is a Kipkay exclusive so
