Zener Diode Tester is controlled by Arduino Nano. Tester measure breakdown Zener voltage for diodes from 1.8V to 48V. Dissipation power of measured diodes could be from 250mW to a few Watts. Measuring is simple, just connect diode and press button START. Arduino Nano gradually connect range of voltages from lower to higher, in four […]

On the face of it, making a clock that displays the time by moving a pointer along a linear scale shouldn’t be too hard. After all, steppers and linear drives should do the job in a jiffy. Throw an Arduino in and Bob’s your uncle, right? Wrong. At least that’s not the way [Leo Fernekes]

Intro What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power supply, as most of the designs out there are using slow components. However, I

This is something I’ve already worked on but was never really happy with the result, mainly because the potentiometre that I used was of poor quality and hence non linear and “jumpy”… The problem is simple: I need to have a reliable and easy to use servo tester, that I can use to test/play with a

When I’m building Solar Shrubs and other solar-powered creations, I often scavenge cells from various off-the-shelf devices such as solar garden or security lights. But these cells are rarely labeled as to their voltage, current, and power output. So it’s off to my bread-boarding station. First, I put each cell under a lamp and connect it to my multimeter to get

A month ago I knew nothing about Arduino and now…..my first project! Looking back, this project combines allmost all of the tutorials that I have read in this short period: blinking LED, push button, piezo and LCD display. A useful project for every beginner! I have made this device for some of my friends who
