Like me, you may have a few old Arduino boards or ATmega8 chips (in the boards) laying around from when you were first playing with Arduino. Those chips can still be really useful as the heart of a tiny “Minimal Arduino” setup. A normal Arduino board contains support components that make it easy to use. …
This example shows how to simulate a simple closed-loop control algorithm in Simulink® and how to run it on an Arduino® board. Supported Hardware: Arduino Leonardo Arduino Mega 2560 Arduino Mega ADK Arduino Pro Arduino Uno Available versions of this example: Arduino Mega 2560 board: Arduino Mega2560 Drive Open-loop Arduino Mega2560 Drive Closed-loop On this …
This is an extremely cheap IR proximity sensor you can make with a few cheap parts and an AVR programmer. I use an Arduino as my programmer in this Instructable. This sensor only has a range of about 3 inches. You can easily add more LEDs or brighter ones to extend the range. You can …

There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you need a special hardware programmer and suitable hex files to program the Atmel AVR chip. Fortunately, Arduino is a beginner-friendly platform …

The other day I wanted to experiment with external triggers for my Canon EOS 550D camera. I stumpled upon a nice open source project called Arduino Camera Control from Oleg Mazurov, the creator of the USB Host Shield library for Arduino. The Arduino Camera Control project depends on the USB Host Shield library and the USB Host Shield from Sparkfun. It supports …
I’ve had an Arduino Duemilanove now for a couple of weeks. If you’re not familiar with the Arduino, it is “an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software”. It has a small microcontroller, a USB port to connect to your computer for programming, a power socket for providing power when the USB …
This tutorial is for all those people who have an Arduino and want to use there Wii nunchuck as an input device, but don’t really feel like cutting open the cord and ruining the nunchuck FOREVER!!!!!!!!well you’ve come to the right place! Step 1: Supplies These are the supplies you will need most can be …
I’ve built a number of projects that have interfaced the output of the Simple Bat Detector with a microprocessor. The most recent was the BatLogger II. But I hadn’t come up with an easy way for others to experiment with this idea … until now. My friend, Frank, in Germany, had wanted to make a relatively inexpensive bat …

Since you lacked the USB interface in your own Arduino board, it becomes necessary to use a homemade/ready-made USB to Serial Converter Module as an efficient and economical solution. Inexpensive and easy-to-use USB to Serial Converter modules are now widely available, such as one shown here. With the help of this little module you can …

A guide to getting started with the ESP8266 with the Arduino IDE This assumes that yo have a NodeMCU type board with the Silicon Labs CP2102 USB to UART Bridge. These boards are convenient because they can be connected directly to your computer for progamming and serial console. NodeMCU pin functions First install the Silicon …
