Tiny Chirp
So I have this Tiny Chirp, when you power it up, an indicator wakes up and it does a sequence of wonderful chirps! First, you need one active piezo-buzzer (i.e. the type with a built-in […]
Quick Servo Tester Nano(v3)
Here’s a nice little project of a quick servo tester with Arduino Nano (v3) microcontroller board. Another key part in this basic project is a cheap Arduino Nano(v3) expansion shield. The hardware setup is extremely […]
Arduino Tachometer
Here’s a simple Arduino Tachometer project for measuring and displaying speed of rotation. You can find similar projects everywhere on the web but this one has some unique features. First off, the idea is based […]
Grey Tracker (v1)
Grey is the neutral achromatic color midway between white and black – Am I right? If you want to make something of yourself to detect the grey, let me give you a cheap and cheerful idea. […]
USBtinyISP Primer
While Googling for nothing, I noticed a little device “USBtinyISP” helpful for programming Attiny85 microcontrollers using the same setup method as for handling Arduino sketches. There’s also no difference in the development environment as we […]
Simple Thermostat for Electric Geyser
Here is a simple yet highly reliable thermal control circuit which can be used with almost all electric geysers. The Arduino microcontroller based circuit switches an electromagnetic relay on or off according to the temperature […]
Digital Pulse Counter
Recently I came to understand the true demand for a multi-purpose digital pulse counter. So I designed an east-to-build digital pulse counter circuit based on some generally available cheap electronic components. The quick microcontroller based […]
