“A 16x16 Red/Green/Blue matrix display driven by shift registers, MOSFETs and a Arduino Pro Micro (old school electronics). This is an extension to my previous Red/Green Disco Tile. By using Red/Green/Blue 8x8 matrixes, more colors …
“Maybe this kind of break-out circuit can be utilized for making other complex and more useful devices or equipment. The potentiometer is a typical analog control device through changing resistance values. Therefore many audio devices such as amplifiers use it …
“Wireless programmable via Wi-Fi room thermostat with air quality monitor and other useful features. Story A commercially available wireless room thermostat works in the autonomous heating system of my apartment. The system, of course, functions without it: the thermostat was …
“Test transistors, diodes, thyristors, resistors, capacitors and inductors. Also identify their leads and obtain their component value. Story When starting my journey into the world of electronics, I obtained a lot of parts by disassembling discarded electronic devices to salvage …
“Always I’m interested in how much current is flowing in the electronic circuits I made. Therefore, I had bought a 1A analog current meter before for measuring the power consumption of circuits. But the analog meter is forgotten for …
“Measure contactless the spindle speed with an optical reflection sensor. I wanted to measure the spindle speed of my milling machine after replacing the motor and installing the PWM variable speed drive. My first attempt I had built a simple …
“MCUVoltage measures the voltage supply (Vcc) of Arduino without extra components. MCUVoltage measures the voltage supply (Vcc) of Arduino without extra components. Supported board includes Uno, Leonardo, Mega as well as the ATtiny3224/3226/3227. This library also supports oversampling …
“Building a few cm precision without GPS RTK. What do you do, if you have a garden to mow, some spare Arduino devices and enthusiasm forembedded and control systems :) You build an Autonomous Lawn mower. If you are not fond …
“In this Instructable I’ll show you how to make my digital measuring wheel (DMW). The DMW is like a traditional measuring tape, but instead using a tape, it uses a wheel that records the distance traveled as it rotates …
“A couple of months ago I got a new roll of pla, I was printing things for a few days without any worries. Last week I went to print a large piece, 200 meters of filament according to Cura… I …
