Stand out from the crowd with this unabashedly ostentatious excuse for a wallet. It’s got plenty of space, RGB lights, and you can even put your name on it for added vanity. Interested? Keep reading! In the files section of this build you can find two things: a Fusion archive and some STL files. If […]

The following code and library are compatible with arduino software 1.0+ ONLY. You can download the newest version of the arduino software here. When you start to talk about biometrics in electronics, heart-rate is usually the first thing to come up. And why not? I think it is often the thing we are most aware
Polar Heart Rate Monitor Interface + Arduino Continue Reading
The objective of this post is to explain how to fade a LED with the ESP32, using the LED PWM functionalities. Introduction The objective of this post is to explain how to fade a LED with the ESP32, using the LED PWM functionalities of the microcontroller. I will be using DFRobot’s FireBeetle ESP32 board to

One of the first things anyone does when they start working with the Arduino is to connect it to a potentiometer and control the brightness of and LED or move a servo. Well, a rotary encoder may look like a potentiometer, but other than also having a knob, it is basically the complete opposite. A
Rotary Encoder + Arduino Continue Reading
This is something I use all the time, so I figured I would share it with you. Controlling an Arduino over serial can be extremely simple if you let it, and extremely useful if you know how to use it. Many languages such as Processing and ActionScript 3 (with a proxy) have ways to communicate

[highlight bgcolor=”ffbb00″]I have collected 2 methods to create laser range finder, one is very simple but for hobbiest the first one using arduino clock but it comes with errors. Its just to conceptulize how we can create range finder. The second one with the The 7558 and 7555 Series Rangefinder/Processor professional one. It uses already built

This is arduino based collision detection warning system. This kind of system is fastest growing safety feature in automotive industries. Such system enables vehicles to identify the chances of collision and give visual and audio warning to driver. So that driver can take necessary action to avoid collision. This project idea is based on arduino

7 Segment LED displays are used in many applications as front panel number indicators. The most common applications are calculators, microwave ovens, electronic lab equipment like function generators and frequency counters. A 7 segment LED display consists of 7 LEDs arranged in such a way that it can display numbers from 0 to 9. The
Arduino 4-Digit 7-Segment LED Display Continue Reading
In this blog post, I am providing you step by step instructions to build a very simple temperature and relative humidity meter for indoor use. All you need to build this project are an Arduino Uno or compatible board, a DHT11 sensor, and a MAX7219 based 8-digit serial 7-segment LED display. The temperature is displayed
