In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
Display can be used like a terminal window (without positioning the cursor before print). Any call to setCursor() has no effect. When the cursor position reach the bottom of the screen, the page is ...
Nowadays, there are evolving projects in robotics, and many hobbyists are creating their own robots. For these Robots, displays are a vital component of an interactive user interface. If you're ...
SCL Serial Clock - The signal that synchronizes the data transfer between OLED and Arduino. SDA Serial Data - The signal used to transmit data between OLED and Arduino. Once you have everything you ...
Using a small custom PCB, a Raspberry Pi Pico 2 microcontroller, a scintillator (typically NaI (Tl)) and SiPM you can build your own gamma spectrometer! The needed processing and multi-channel ...
A breakout board for the Sharp LS011B7DH03, a 1.1-inch, 160x68 pixel monochrome memory display. This display is ideal for low-power applications like wireless keyboards due to its e-paper-like ...
A compass and a protractor are two of the most basic tools used in geometry. For mathematics and engineering students, these tools are a must. But sometimes it is difficult to get accurate angle ...
It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware ...
