This is the second part of our BaW-Bot (Bells-and-Whistles Bot) build – 5 separate instructables that look into different Arduino-related technologies, combining to create a Bot with all the bells-and-whistles. Part 1: Build an Arduino on a Board Part 2: Build the motor-controller & body Part 3: Adding Sight and Touch Part 4: Blinging up […]

A long while ago I wrote about that I might make a series of boards for easier testing of the open USB stacks. Testing all different version of mcu’s and crystal speeds to make the right #defines and linker maps for the firmwares can be a bit tedious. OSUS will make life a bit easier […]

This is a very low cost and basic from of home automation allowing you to turn on and off lights and other devices using your computer or mobile phone. It has been built and tested use using UK power plugs, but the same protocol is used on many budget remote power switchers from around the […]

TLF4277-2EL Description: The TLF4277-2 is the ideal companion IC to supply active antennas for car infotainment applications. The adjustable output voltage makes the TLF4277-2 capable of supplying the majority of standard active antennas such as: • FM/AM • DAB • XM • SIRIUS The TLF4277-2 is a monolithic integrated low drop out voltage regulator capable […]

One of my colleagues, Dr. Shane Mayor, has built a very nice LIDAR system for atmospheric research. It’s located at a remote site, at the end of a dirt road, and everything about the system can be controlled remotely except the main pump laser power supply. That supply has a key-switch, which has to be […]

To connect a 12V relay to the Arduino you need the following things: – 1 Arduino – 1 diode for example 1N4007 – 1 NPN transistor for example 2N2222 (in the US) or BC548 (in Europe) – 1 relay for example one with coil voltage 12V and switching voltage 125VAC/10 A – 1 multimeter Step […]

Being a broke amateur photographer isn’t easy. Film, chemicals and paper aren’t cheap and a budget for some studio lights is non existant. So, I decided to, with the help of my trusty arduino, create my own sync controller to use with disposable camera flash circuits. By using a photoresistor the arduino can sense when the flash from your […]

Hey everyone, I wanted to share a project I just finished up. I built a super secret locking box for my girlfriends little brother. He has a knack for creative lego building so I thought it would be a good idea to open him up to the Arduino as soon as possible. The super secret […]

After a bad water damage (our cellar basically filled up whilst we were away for several days), I decided to monitor our water usage for anomalies. Enters Arduino… The idea of this project is to use an arduino to count every drop of water that goes through the water company meter. Said arduino needs to […]

Flat displays of the EA DOG series are now available even with a bigger resolution or with more characters. EADOG series is familiar to many of you and probably it´s your favorite one from these main reasons: ● displays are unusually flat (thin) ● the have a very low power consumption of 100-s uA (without […]
