Check out the detailed guide on Instructables to hack this project. If your kids love this one, it is time to introduce them to more DIY projects to spark their creativity. If you love taking strolls around your yard just to see how everything is but never get the time to do it, you’ll love this Arduino-controlled 4-wheel drive security robot. It features a pair of cameras, a controller with more than 400 yards range, and a reflector to illuminate the surrounding area.
Using the RCWL-0516 radar sensor to detect motion. Using an Adafruit compass/accelerometer and an 80-decibel alarm, this project prevents thieves from stealing your backpack. 5.2 Then slowly introduce any obstacle to check whether your circuit works fine. Since the distance b/w the LEDs will be quite less, you can even introduce a black paper/scale/ etc. 5.1 Bring both the circuits completely closer to each other.
Interfacing IR sensor and PIR with Nodemcu ESP8266:
Yes, the circuit instructions were built with the intention that beginners could build it. Check whether the negative terminal of the buzzer and the green wire going to the NO terminal of the relay are connected in the same column. In the void setup function I activated the serial communication.
Electronics Project Design references and tips for high school students, teachers, colleges and university students, electronics hobbyist and electronics designers. Test your hardware and software skills against the best designers from the rest of the world. Once the contact is momentarily closed, the first timer which is configured as a monostable output will output a high pulse with a duration up to a maximum of 220 seconds. You can also purchase a device like the Defender Security Reinforcement Lock to give door kickers a hard time. Attach contact sensors to your home’s windows and you’ll know right away if someone’s trying to get in. If you were to check your home’s windows right now, chances are you’d find some were carelessly left unlocked or have inoperable locks.
4WD Security Robot
Here are ten basic DIY projects to significantly improve your home’s security. In this Instructable, i decided to use an old mobile phone to make a simple Home Security Alarm which is very useful and easy to make DIY gadget. This is one of a cool things that can be done with old cell phones. Any working phone with keypad that has speed dialing feature can be used to make this Security Alarm System. In this project, you will build transmitter and receiver circuits using an IR LED and a photo-diode. The circuit is based on obstacle detection when a person or thing comes in between the transmitter and receiver.
This control system consist with the menu driven configuration options, self tests, system report generators, etc. This system also contain 5W (with 4Ω speaker) audio alarm with three selectable tone configurations, which include Police siren, Fire engine siren and Ambulance siren. Do you want to up your home’s security but can’t afford the high price tag on CCTV cameras? This security camera lamp build on Instructables is just what you need to scare off intruders and light up your home’s space. You can opt to purchase a dummy camera or DIY your own using old cans to hack this project. The process of making a mouse security alarm is pretty straightforward, as shown in this Instructables guide.
Solar-Powered Security System
Read on to find out how you can work with a Frankfurt, Hesse, Germany home media, smart technology or automation installer to bring your home into the 21st Century. This simple standalone home alarm project is a good project for those who are eager to know the concept of home security system. This circuit which consists of three 555 timers gets the input from a contact that could be connected to a motion detector or any momentary contact that monitors a certain process. Motion-sensing security systems can cost an arm and a leg, but why spend your hard-earned money on one when you can build one at nearly a quarter of the cost? You will need an Arduino Uno, a PIR motion sensor, a couple of jumper wires, a loud buzzer, a power supply, and all the supplies and instructions in this easy-to-follow Instructable.
In our house, we have two teenagers and 1.5 bathrooms. They both like to spend a very long time taking showers and getting ready... A device that warns us with light sound and a sign when our plant needs water. One last thing, if your circuit still does not work, we will be happy to send you a free pair of powerful IR LED and photodiode. 5.2 Once you reach there, keep the transmitter circuit fixed and slowly move the receiver circuit keeping the line of sight intact.

The output of U2 timer is used to feed the control voltage of the U3 timer through resistor R6 where it is subjected to frequency modulation. This frequency modulation will generate a tone similar to the police siren. The frequency of this tone generator can be varied by changing the value of potentiometer VR2.
The sensor detect any motion in its permissible range and triggers the alarm. Make an alarm clock that will only stop once the light is on and the button is pressed using an Arduino Nano. You can attach it anywhere and will it will inform when someone tries to steal something. The positive terminal of the photo-diode in the receiver circuit must be connected to ground. This is the same function I have been using in all of my IoT based projects.
If you want to learn how to make a schematic and PCB then watch my video tutorial. Each time an Intruder is detected a notification message is sent to the Blynk application. With the help of the Nodemcu ESP8266 Wifi Module, the PIR Sensor and IR Sensor can be monitored from anywhere around the world. When a burglar breaks into your home through the basement, chances are you won’t hear them until they are smack in the middle of your living room, waving their weapon in your face. Even if your basement doesn’t allow direct access to your home, they may break in and steal the valuables you store down there.
But you don’t have to sit and worry about it happening. With this Instructables project, you can build a simple yet effective alarm system that instantly goes off whenever an intruder tries to access your basement. If you follow this Instructables guide, you can build something close to that as part of your security system. It may not feature a laser maze with sophisticated man-sized holes, but it’s invisible and will instantly trip and set off the alarm whenever an intruder attempts to pass it. Hook it up to an existing security system, for instance, floodlights, or any loud external device, to enhance its efficiency. Build this simple home alarm to protect your house from intruders.
The first timer U1 is configured as a monostable timer with a variable timing of up to a maximum of 220 seconds. The timing can be changed by adjusting the VR1 1M ohm potentiometer. If you need to further increase the timing, the electrolytic capacitor E1 can be changed to a larger value. Once the contact CT is momentarily closed, a pulse will be generated at the output pin 3 of U1. I created an alarm clock using a motion detection sensor so that you're not able to just hit the snooze button and go back to sleep. This alarm clock and timer work without the help of a computer.
