In July of last year, we talked about the BeagleCore which is a miniature version of the BeagleBone Black. BeagleCore had a Kickstarter in the coming months, but were unable to reach their goal. But it looks like they kept on and have now released the two versions of the BeagleCore, including the gerbers(not the […]

In Circuit Serial Programming is a method of directly programming a Microchip PIC or Atmel AVR while in they are connected to a circuit, as opposed to programming the chip ahead, and only then soldering it to a circuit. There are many benefits to ICSP, but also some important design considerations which I will try […]

I have seen many examples of microcontroller oscilliscopes on the web and have had an itch to build one myself.  In order to accomplish this my initial thought is to sample an input (ADC) at consistant time increments and then display the waveform on a graphic lcd display.  If I want to change the time […]

Step 1: COMPONENTS REQUIRED 6 components needed : 1. Microcontroller (I have used AT89S52-8051 family), any programmable microcontroller can be used. 2.7 segment display 3.Crystal oscillator (12MHz) 4.Capacitor (10uF, 33pF/22pF) 5.LEDs 6.resistances (330 Ohm) 7.buzzer (piezo) 8.push switches And I’m not including soldering iron, wire, flux….. electricity !!! help me out 🙂 Step 2: Circuit Diagram   This […]

Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas[1] and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement […]

ABSTRACT The heart rate is an important measure of health and physical fitness. Medical professionals rely heavily on the rate as a measure of health status and use it to prescribe treatment to individuals. Athletes value the heart rate highly as a tool for regulating frequency and intensity of workouts because the rate provides a […]
