The 28BYJ stepper motor is a terrific device but it presents some design challenges. Here is a way to overcome those challenges.
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 […]
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.
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, […]
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 […]
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 […]
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 […]
