If you need an Arduino to shut off from within your Sketch, this is the solution. We will explore wiring the Pololu Pushbutton Power Switch, programming the Arduino to shut off the power, and making the unit “power on” only. The Pololu Pushbutton Power Switch comes in two versions – the SV version geared towards […]

This example shows you how to monitor the state of a switch by establishing serial communication between your Arduino and your computer over USB. Hardware Required Arduino Board A momentary switch, button, or toggle switch 10k ohm resistor breadboard hook-up wire Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to

Adding an LCD display to Arduino projects can add real value but the cost of doing so can be significant. Not a financial cost – you can pick up 16 (characters) x 2 (rows) LCD for as little as £3.50. The cost is the pin count it can take to drive them. Using the built-in

This mini project is involved to use Arduino to control submersible watre pump when soil reach below or above predefined moisture level. How it works ❓ 1. Soil moisture sensor is reading analog signal which transmit to Arduino. 2. Arduino control submersible water pump ON or OFF. Water pump operates when moisture level reach predefined

An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use it to switch between four desired states

This Instructable shows how to create a Barcode Reader using only a webcam together with Roborealm and Arduino. The webcam used in this demonstration is the Logitech Quickcam and the LCD screen is labelled, JHD162A. What you need for this project: 1. Arduino UNO 2. LCD 3. Roborealm 4. Potentiometer Step 1: Coding the Arduino

L3DGEWorld is a tool for monitoring and interacting with networks and computer systems. Within a 3D world, entities bounce, spin, scale and otherwise change. These entities all represent an entity in another context – be it a server, phone, router or other monitorable device. The visual transformations represent various characteristics of these entities, such as

I had been looking for a cheap alternative to some of the Arduino Bluetooth devices I’d seen, which in my opinion are overpriced. Redbear’s Mini: $39.95 (Note: This is a uC and BLE combo). Redbear’s Uno Shield: $29.95 BLEDuino: $19.95 (if part of Kickstarter) Bluegiga Shield: $69.95 After seeing these, I thought I’d try to

This project slightly modifies the Google Android sample app called “Bluetooth Chat” so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno. Functionality: Android talks to Arduino 1. Run the Android “Bluetooth Chat” sample app (after we modify the app in

In this video we will have a closer look at a USB Type-C Power Delivery Trigger board. Such boards are used to output 5V, 9V, 12V, 15V or even 20V from a Power Delivery compatible power source. So I will be showing you how such a commercial board works and I will try to create
