Arduino Projects

This project makes the “dots” on a dot matrix look like they are pebbles in a container. Tilt the device on one side and the dots fall toward that side. The same goes if the device tilts to the other side.

Introduction This week’s Arduino project is a classic one and ideal for beginners. Here I will be showing how to build a simple clap switch for a RGB LED strip. Basically, a microphone captures the sound of the clap and converts it to a voltage. The Arduino processes that voltage …

Flame sensors are found from the simplest gas stoves to huge industrial plants. There are different types of fire sensors -- some cheap, some expensive. Yet they’re all built for one single purpose: detect fire. In this article, I will guide you on how to build a flame sensor with …

In general terms, a magnetometer measures the magnetism of objects or places. In fact, a compass is a type of magnetometer. This project demonstrates how to use the HMC5883L magnetometer as a compass with an Arduino microcontroller.

This project demonstrates how two bluetooth modules connect with each other. I’ll be featuring DFRobot’s Input Shield V2 as the transmitter/controller and Seeed’s ShieldBot, which was seen on my Bluetooth RC Car project, will act as the receiver.

To kick off 2019, I would like to create a series of Arduino Robot projects that anyone can learn how to build. The first part of the series is the popular obstacle-avoiding Arduino robot.

This project demonstrates how to send data to ThingSpeak using a SIM800L breakout board. The data will be coming from a BMP085 atmospheric pressure sensor and will be using the SIM800L GPRS connection to publish this data to ThingSpeak.

I made this project because it seems a lot of people are having trouble with interfacing the SIM800L with an Arduino, particularly in connecting to a network. Here, I made a simple setup where I was able to display the signal level and the network status on an LCD. This …

This Arduino LiPo battery monitor and charger features the TP4056 breakout board. The voltage of the battery is displayed on a Nokia 3310/5110 LCD with the Arduino Nano as the microcontroller. Materials Arduino Nano TP4056 Breakout Board Nokia 3310/5100 LCD 3.7 V LiPo Battery Connecting Wires Breadboard Introduction [the_ad id="3059"] …

This Arduino Altimeter project features the BMP085 atmospheric pressure sensor by Bosch. Because atmospheric pressure is directly related to altitude above sea level, we can use this sensor to determine current height with respect to the height of the oceans. The height is given in meters and is displayed on …
