Easy Serial on the ATtiny

Introduction The Atmel tinyAVR MCU's are great little chips for projects but can prove difficult to debug. Some ATtiny chips do not have direct support for hardware based serial and therefore the Serial object is unavailable in your code, however, it is easy to add a SoftwareSerial object and view output in the Arduino IDE. The code in this article uses an ATtiny85 with an FTDI Serial TTL-232 USB Cable to s ...

Isolated mains power monitoring (Arduino)

All about power today.. For a while now, I’ve been looking around for a mains (220-240VAC) power monitoring circuit that I might be able to interface with an Arduino.  There is of course the OpenEnergyMonitor solution, but they seem to use a transformer to isolate and measure the mains voltage.  The transformer doesn’t exactly couple to the mains nicely: so the voltage on the secondary side is not a scaled ...

D-Led Shield v1.0 (for monitoring)

Good day fellow enthusiast! Here is one of my latest and simplest shield designs for an arduino board. The thing here is, sometimes we have a hard time checking out which I/O pins are LOW or HIGH, especially when we are dealing with LED, motors, etc. Now, here is one of the solutions that you can make in order to have yourself a smooth sailing progress in programming your prototype or project. One of the sh ...
