I bought a solar powered garden light. The solar panel charges the batteries and when it gets dark the lights (3x LEDs) turn on until it either gets lights again or the batteries run out. First, the batteries. The control box houses the batteries, which are.... -
In this instructable I use an example of interfacing an Arduino to an ARINC 429 transceiver in order to demonstrate the general process of interfacing an Arduino to electronic circuits so you can use these techniques on your own designs. An ARINC 429 bus is.... -
Example if you press number 8 it will effect the wire ROW3 and CLO2. By this the microcontrollercan determine what key was pressed with only 7 wires from the keypad. .. -
Man has long wrestled with Time. Also, with knocking on things and not getting the time of day. We propose a knocking platform through which these fundamental needs are met. This is illustrated with the Knock Block KUI and accompanying Clock Knock Block.... -
A ascends a route while Climber B stays on the ground and tracks Climber A`s progress with the laser pointer. The Redpointer then records exactly what route was followed. Here, the route recorded in Mode 1 is played back in real-time, projecting a laser.... -
7-Segment LED Display is a very useful component, but also a very confusing and difficult piece to use for beginners. It won`t be difficult once you get it working for the first time. It basically consists of 7 LEDs, (8 if include decimal point). Just like.... -
A while ago, as my first microcontroller project, I made a Pong game on a 5G—7 LED display, but then nothing became of it. Recently I was given a hard hat as part of a uniform (for an engineering competition) and told to customize it, and remembered pong..... -
In case the robot being on the black line, it will always go ahead, and in the case of out of line and fall into a white area, it will determine whether to correct to the left or right, and thus remain on the black line. The sensors that will be used is the.... -
One of the most interesting shield that you can mount on the Arduino platform is certainly the ethernet shield, because enable numerous networking applications such as remote control of systems and users, web access and publication of data, and more yet, the.... -
This was my very first arduino project. Its great for beginners. Fade the color or the lights my moving your hands near it. It fades from a pretty purple blue to a firey red-orange. Its was SUPER easy to build, not to hard to write the code, and its really.... -
When I purchased the salve dial, it came with no instructions, packaging or other details. The only markings (other than five decades of grime) were those on the face (SMITH SECTRIC, ACELEC SYDNEY), and some markings on bracket holding the mechanism together.... -
This Lazy Old Geek is also an Arduino Geek. If you are an Arduino Geek, one of the common microcontrollers used by Arduinos is the Atmega328 chip. In order to use Arduino software, the Atmega must have bootloader software on it. I didn`t realize there was a.... -
ATMega168 or 328microcontroller chip w/Arduino bootloader (you can use the one on your Arduino for now!) $4. 00-$5. 50 - buy unbootloaded mouser (cheaper) / buy bootloaded sparkfun (expensive) I have created a Mouser project that includes everything you will.... -
