In this Instructable we’ll make a robot (more like a RC car) which is controlled by voice i.e. Voice Recognition. Before I start to give you any further details one must know that this is Voice Recognition and not Speech Recognition that means the controller does not understands what you are speaking. This project uses […]
We all like to know what the current room temperature is, and sometimes what the temperature is in another room, or maybe even in your vacation house on the other side of the world. Maybe you want to monitor the temperature in your pet Lizard’s house? You’ve come to the right place to learn how […]
We wanted to build a model police car with working lights and sirens. Then we decided to add a motor and instead of using a switch to turn everything and off we used a photodiode. For our car the photodiode signal is a simple on off switch. If you want a more complicated device that will […]
Don’t let a clogged drain slow you down!Coming back from our vacation, me and my wife were surprised by the water covering the floor of our apartment, and we found out it’s not even clean water, it’s drain everywhere. After clearing the drain and cleaning the floor, I had this question: why don’t we have […]
The big problem using the ESPs is the power consumption when Wifi “goes up”, about 100-200mA, peak up to 300mA. Normal coincells deliver a few mA, peak up to 20-40mA. But for the ESPs the voltage will collapse. We need “a little help of my friend”: the supercap. These capacitors deliver enough current for power […]
Have you ever given something to someone and wished that the box you gave it in opened automatically? No? Well neither have I (well, maybe) :D. However if you have, this is the guide for you! With just a flick of a switch the box will open automatically! Step 1: Tools & Materials Step 2: […]
The aim of this project is to make latte printer, I used 1 printers and 1 scanner , it prints one line a time, all what I have done is hacking the sensors of the printer and I used Arduino Uno to send different values to printer’s micro-controller created custom shield to control stepper motor […]
Introduction I have a laptop on a shelf in my office that monitors several cameras that are around the outside of my house. They alert me to deliveries and visitors. While I can use a web browser to see their images it is easier to just glance at the screen on the laptop from time-to-time to […]
Colour reading is a real issue for industrial models. I’ve been working on it for more than 12 months now, since December 2009. After many months of hard work, • starting with the standard colour reader (season 1 ) with features a red LED, • adding extra light from bulb lamps (season 2 ), • […]
In this instructable I will show you how to make a 4x4x4 LED cube that will be controlled by an Arduino Demulionove. now yes you might say” that Arduino has only 14 I/O pins well also the 6 analog pins can be used as pins 15,16,17,18,19,20. that way giving us enough pins (16 columns + […]
