In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is no “one size fits all” but I will try and generalize as much as possible. The idea is to…

[Blecky]’s entry to the Hackaday Prize is MappyDot, a tiny board less than a square inch in size that holds a VL53L0X time-of-flight distance sensor and can measure distances of up to 2 meters. MappyDot is more than just a breakout board; the ATMega328PB microcontroller on each PCB provides filtering, an easy to use I2C interface,…

From Jeremy Cook on the Tindie blog:
simply plugs into the I/O female header pins on one side of an Arduino UNO, and allows signals to pass through its own headers while lighting up to indicate what is HIGH and LOW
A couple years ago my TV remote broke. I had used one of those universal remote phone apps as an alternative for a while, but that just got really frustrating. Without the tactile feel of buttons it was too easy to press wrong buttons on my smart phone; accidentally pressing mute, stop or changing the channel / input, etc.
I considered just ordering a cheap replacement remote off of Ebay for a few dollars but part of me wanted to take advantage of the situation and make one from scratch using the atmega328p chip used on the famous Arduino Uno. I had been tinkering with the atmega chip quite a bit at the time and was also exploring the process of designing circuit boards using cad software.
I loved the idea of designing a circuit board from scratch & filling it with circuits. This seemed like the perfect project for me – being able to use my beloved arduino chip, design and populate a circuit board with circuits & fashion some kind of project case (altoids tin) to put it all in. I went for it.

From Jeremy Cook on the Tindie blog:
For those of you reading this that are generally quite clumsy, favoring electronics that use screw terminals over everything else, then perhaps you should stop reading here. Yes, today I’ll be talking about surface mount devices, commonly known as SMDs. According to the Collin’s Labvideo seen below, “The process is pretty straightforward once you get used to the scale,” and “It’s actually quite relaxing.”
[dombeef] originally built pocketTETRIS as a Father’s Day gift for his Tetris-loving pops. However, having finished the project he’s decided to share it with the universe, and it’s looking rather sweet. He made the game the smallest he could make, with size limitations imposed by a 0.96” OLED display, the coin-cell battery pack, and his desire…
