BotTender, a bartender assistant that pours the perfect shot! BotTender is an autonomous robot that is designed with the aim of automatising bars. It is placed on top of the bar and detects the shot glasses in front of it. Once the glasses are detected, it approaches to the glass and asks for the customers […]
In this project I will show you how I combined an Arduino Nano, a current sensor, an LCD, a rotary encoder and a couple of other complementary components in order to create an adjustable constant load. It features a constant current and power mode and can handle a maximum of 30V and 20A if your

This instructable explains how to make a tilt compensated compass using an Arduino UNO R3, an LCD display, and an IvenSense MPU-9250 multi-chip-module that contains an MPU-6050 accelerometer / gyro and an AK8963 magnetometer within the same package. The LCD simultaneously displays the Heading, (P)itch, and (R)oll. The heading accuracy is within 2 degrees depending

We’ve all been there. A big bag of resistors all mixed up. Maybe you bought them cheap. Maybe your neatly organized drawers spilled. Of course, you can excruciatingly read the color codes one by one. Or use a meter. But either way, it is a tedious job. [Ishann’s] solution was to build an automatic sorter that

Espruino is a small computer that anyone can use to control things around it. Its JavaScript interpreter gives you instant feedback so that you can experiment and develop whatever your level of experience. Even if you can’t program, you can still get started quickly with the web-based graphical code editor! The Espruino family started with one

Most of the temperature measurement techniques around the world require some sort of physical contact between the temperature sensor and the object or environment whose temperature is to be measured, but as technology advanced, this changed too. The need to be able to measure the temperature of an object without physical contact arose. This need

Hi everyone, I work as a builder even though I’ve been always really interested in new technologies. I’ve learned a little about 3d printing, Arduino and electronic issues reading a lot. I visit this web regularly so I would like to make my little contribution. In my job sometimes it is not so easy to

We have seen a fair share of unusual items being turned into musical instruments. Luckily, with a little bit of hacking it is possible to turn almost anything into a MIDI controller. [William Sun Petrus] just converted a 1920s typewriter into a drum machine and delivers a hell of a live performance on it. The build

During weekdays, I seldom bring my key out, but this causes difficulty when my mother left the house. By having no other choices, my mom has to leave the key inside the cabinet beside the door, which has no guarantee of whether the key is safe or not. By having this key lock, the one
In this guide I will show you how to make your own Arduino learning shield. This learning shield can be useful at schools, universities and to everyone that want to start dealing with the Arduino. With this shield you will learn how to read the temperature and humidity from DHT-22 sensor, read an object distance
