We have finished our DIY Arduino on a solderless breadboard, and are about to move it to a perfboard for adding additional project components. We wanted to share this stage of the project to make it easier for others to
A important part of breadboarding is supplying the proper power to the circuits you are building. We prototype on solderless breadboards, then move the circuit to a solder type protoboard that matches the solderless breadboard. We do this to make
We are in the process of building some projects with an embedded Arduino, instead of using a Arduino board. Hacktronics.com sent us some new Atmel 328-PU chips for this purpose. These chips are new, without a bootloader installed. The bootloader is
A Motion Sensor is a good way to save energy, by turning lights on and off based on the presence of a warm body. Walk into a room, the lights come on, walk out, and they go off. We can build in
A long while back (in a galaxy very far away), we built a temp and humidity monitor with the SHT-21 chip. It’s a very accurate, albeit very expensive, solution. What if good enough, is good enough? If you don’t need
Today we are working with our SainSmart 5v Relay Board. This is a simple and inexpensive 4 port SPDT relay board (there are boards with more or less relays) that takes a digital signal (LOW) from the Arduino, through an optoisolator, which triggers a
