A popular, traditional way to power electronics projects had been to use a DC power socket with an external power supply. DC power supplies with a power jack (e.g. a “2.1mm jack”) are readily available and quite affordable. Speaking for our projects, we often brought in a 9V/12V DV power supply and employed a 7805 […]

An example of how a Bezel makes an electronic project look more professional
For home/DIY projects, it doesn’t matter how good the internals are. If the externals don’t have a quality finish, then you will always be that little bit disappointed. Here is how to be NOT disappointed.
How to mount an OLED directly onto a PCB
A commonly used display for Arduino projects is the 0.96″ 128×64 SSD1306 OLED display module. Using it in practice can present problems….
Using the TM1637 LED Tube display
Using this nice 4-digit display with your Arduino Although the more-graphical displays are terrific (and some are cheap to buy too) , sometimes your application doesn’t need the added coding complexity. And for some projects, a “traditional” 7-segment display is simply a better choice for the project at hand – for example, clocks, GPS speedometers, […]
Solving the OLED Display mounting problem
0.96″ (128×64) and 0.91″ (128×32) OLED displays are very common and available at low cost from online stores such as eBay. But there is usually a BIG a problem with them! (actually this problem exists with most displays). The problem with most OLED displays The OLED displays available from online shops do not come with […]
How to mount a 0.91″ OLED display
The 0.91″ 128×32 OLED Display is a terrific little display. Its crisp display needs no backlight, it only has 4 pins (I2C), it is small, easy to code-up, readily available and, well, low cost (i.e. cheap). For my own more-complex projects, I often add one directly to the PCB just as a diagnostic tool, helping […]
How to make an Arduino project with a 5110 display
Using the terrific 5110 LCD display with an Arduino The 5110 display was original made for use in mobile phones (e.g. the Nokia 5110) and so it’s sometimes called a Nokia 5110 Display. The display is low cost and low power, and relatively low resolution (84 x 48 dots). And although their resolution is lower […]
