Automatic gesture controlled Table Lamp - Main light control system for study.

Arduino and PIR motion sensor based automatic multiple light control system. Room light on - TableLamp off. Room light off - TableLamp on. Perfect device for study. Control things by just waving at them.

I've built a PIR motion sensor based automated light / Appliances project which can be found here. This project is a bigger version with relay to control 220V lights.

FEATURES-

Table lamp ON main Light OFF
Table lamp OFF main Light ON

PARTS YOU'LL NEED -

Arduino pro mini (or any board)

2 Channel relay module

Buzzer

PIR motion sensor

220v to 5v converter
wires
hot glue

THE CIRCUIT DIAGRAM:

Making the project:

I've built a PIR motion sensor based automated light / Appliances project which can be found here. This project is a bigger version with relay to control 220V lights.

Just added the lights switch wires to relays and powered the arduino and relay module using a 220 to 5v converter - for that I've used a mobile charger which gives 5v in output.

Then I put the entire circuit into a plastic box. Note that I've made some tiny holes on the lid because the relay's get warm and it is needed to get some air.

Make sure to secure all the exposed wires and to cover them with glue gun for extra security.

THE CODE -

Uploading code to arduino pro mini (5v 16 mHz)

Arduino pro mini doesn't have USB programming option. So you may Upload code using a USB to TTL converter. Or you may use an Arduino Uno. We all have an uno right?

So let's upload code using an arduino Uno.

Remove The ATmega IC from Uno (using a screwdriver) [be carefull not to harm the IC]

Connect Arduino pro mini ------ Uno as following

TX to tx

Rx to rx

Vcc to 5v

Gnd to gnd

rst to Reset

Then start arduino.ide and go to tools>board> select arduino pro or pro mini

Note: You can just upload code to Arduino pro (5v 16 mHz) mini using UNO not the 3.3v one. Check before you buy one.

Download the code from the github link and upload to arduino. That's it.

Then power it up and enjoy. Thank you.

Make a Smart Phone Controlled Robotic Arm ! Arduino DIY.

Making ROBOT ARMs is very popular and fun among hobbyists, but it's not that easy to control a ROBOT ARM. So today we'll be making a robot arm that can be controlled using just your Android Smartphone or tablet. Good news is, you just need to program the Arduino, the App is already available to download for free. Step 1: Parts You'll Need 2 More Images Servo motor 4x (I'm using micro servo Sg90 but any model or size is okay) you can use upto 5 servo for this robot arm, I've only 4, so I'm using them. sliced piece of Card Board - to make the body. USB OTG (on the go) [pic3 & 4- all the same] And of course a Arduino board (any board) And a few jumpers to make the connection And a 9v battery to power the servo motors. Step 2: Making the Robot Arm (THE BODY) Now in here I'm actua...

Make a Smart Humanoid Talking Robot- MOFIZA.

This Robot - Mofiza - (weird name) Can SEE , TALK and REACT to her surroundings. Before I proceed watch the video: Ever since I've seen making talking robots I saw that people actually use other development boards rather than Arduino to make talking robots. But it's completely possible to make a Humanoid robot with Arduino who can talk and add a lot of servos to make it move. So lets begin: Step 1: Parts You'll Need Arduino Pro mini (5v 16 Mhz) [any board is good but i've used this to make it small) Female header pins for connecting on pcb Male header pins Vero Board to make the circuit Sd card TF module (to make it talk) micro sd card (not more than 2GB) 3x IR proximity sensor 3x servo motor (I've used micro servo sg90) Cardboard to make the body Step 2: Connecting IR Sensor and the Body Make a...

Make AI Assistant Robot with Arduino and Python

Introduction: We all are familiar with ‘Jarvis’ AI assistant robot from “Iron Man’ movies and Marvel series. It has always been a dream of programmers to make something on their own. I will today show a simple way to make such an assistant using Python programming. Moreover, I will also make a physical avatar of that robot, so that whenever we talk to the robot, it can do some movements. That will be more amazing than just a software robot. Because if it has a body, it is cool. So today we will learn to use both Arduino and Python programming to make an AI robot which can control your computer and have a little chit chat with you. Let’s hop in guys! Why I named the robot ‘Jaundice’? Because I painted it yellow, very very yellow! Parts: Electronics - Arduino Nano – 1x Micro Servo Sg90 – 3x Ultra Sonic Sensor HCsr04 – 1x Body – PVC sheet (preferably white, better for coloring, I used blue one) Servo wheel (for the stand) Tools - Cutter knife Scisso...

Arduino Automated Parking Garage

An Arduino Automated Car Parking System that is too easy and too fun to make. When a car arrives it shows the number of empty slots (if available) and then opens the gate. if there is not any empty slot then the gate does not open. Amazing thing is that the whole project can just be POWERED using a POWER BANK!! Watch the video for the full tutorial. Note: you can use display instead of my hand made led sign display. Now lets get started. Step 1: Parts Arduino - any board Infrared proximmity sensor (pic 2 & 3 - both are functional) 330r resistor some LED 's Servo motor - any model or size you wish. Step 2: Making the LED Display To make this LED display I have used a piece of bredboard then soldered the LED's and the 330r resistor. Then j...

Problems using PIR sensor?? Always HIGH? DELAY? Solution is here.

PIR sensor When I was working on a project "controlling home appliances using just a wave of hand" I had used a PIR sensor and found some issues: PIR doesn't work properly when starts. PIR output value is always 1. It some times doesn't read motions. Now those are three Common and Unavoidable problems of a PIR sensor. So what would we do? I assume you know what a PIR sensor is and I'll just try to give a solution to the problems so that you can use PIR in your project efficiently, also I've added a code below on how to solve that problem. As I have mentioned earlier those are Common and Unavoidable, keep 3 issues in mind: After powering - PIR sensor needs 1 minute to function For that 1 minute the OUTPUT is always HIGH. When a motion is detected it'll take 5 to 7 seconds to detect motion again. SOLUTION: After powering - PIR sensor needs 1 minute to function: which means when you'll power a PIR sensor it wi...

How to use ServoTimer2 Library with Arduino- full tutorial.

Introduction I've been trying to make a humanoid robot MOFIZA -Arduino Talking Humanoid Robot. recently- which means dealing with Servo motors. Everything worked just as fine just before I tried to make the robot TALK. When I needed to use the TMRpcm library. But there's some libraries like #TMRpcm .h #VirtualWire .h are libraries that use the Timer1 of Arduino. It appears that you can't use two devices simultaneously where both use the same timer...So, if my robot talks- the servos don't work. Because The Servo.h and the TMRpcm both works on Arduino TImer1. Which is a mess. If you want to make both of them work you have to use another library for servos. Which is ServoTimer2 library? This uses the Timer2 on Arduino...Unfortunately on internet I haven't found any tutorials to understand how this ServoTimer2 library actually works, and how to use it in code. So, I've decided to make a tutorial so that people like me can understand better. We'll be u...
