MCM Electronics Daily Deal and Bulk Bargain

DIY Sanguino

Posted August 16, 2017 by Chris

"A few days later it was in my hands. Of course I wasn’t the first person to think of this. This kind of board goes by the name Sanguino and more info about them can be found here: http://sanguino.cc/start. That website has all the info you need to build your own, but I’ll show you how I did it with basic, cheap components."

The Cherry Express

Posted May 27, 2017 by Chris

"Finally got the linebot working reliably. I’ve uploaded 3 images and a movie. I also included the modified Arduino script provided for the “method 1” servos and “V2 Adafruit_Motorshield” I’m using. My sensor board image shows the original 5 sensors described in your “Arduino Robotics” book, but you’ll notice now only the three middle sensors have signal wires, to match the 3-sensor script you provided. "

LED Open Sign

Posted March 25, 2017 by Chris

"In this open source hardware and firmware project, an LED “Open” sign is built using an ATtiny2313 microcontroller. This is the type of sign that would typically be used in a shop or restaurant to show that it is open for business."

GPS Transmission With HC 12

Posted March 22, 2017 by Chris

"The first article in this two-part series, Understanding and Implementing the HC-12 Wireless Transceiver Module, uses the HC-12 to create long-distance data transmission between two Arduino Unos."

DTFM Controlled Robot Using Arduino

Posted March 19, 2017 by Chris

"In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy."

Portable Ultrasonic Range Meter

Posted April 29, 2016 by Chris

"Sound is a phenomena that is a result of vibration of materials. Sound is characterized as a mechanical wave that carries mechanical energy. For the transmission of this energy between transmitter and receiver, presence of a medium is necessary. The medium can be solids, liquids or gases."

ASCII-ART Arduino Pinouts

Posted March 27, 2016 by Chris

"To enable easy documentation of pin assignments, I created a couple of ASCII art arduinos; complete with ports, PWM and coms all marked. Simply paste as a comment into your code and marvel at your new found organisation."

ISPnub – Stand-alone AVR In-System-Programmer Module

Posted March 1, 2016 by Chris

"ISPnub is a simple to use stand alone programmer intended for flashing AVR controllers in the field directly in the target system or during production. The module has only one button and two leds as user interface."

How To Write A Library For Arduino

Posted February 21, 2016 by Chris

"Libraries are files written in C or C++ which provide sketches with extra functionality, for example the ability to control an LED matrix, read an encoder, connect to a sensor, display, or module, etc. They are very useful to lower the barriers for creating amazing interactive projects and use a wide range of components. Libraries can be created by everyone and shared with the open source community!"

My Business Card v2 (PCB Card)

Posted January 11, 2016 by Chris

"At the end of this month, I’ll be leaving my current job. I therefore thought it’d be a nice occasion to build a new business card for my future interviews. You may remember the first version of my business card made more than one and a half years ago (time flies!). It was basically made of two PCBs soldered together."
