Arduino Mini

The Arduino Mini 05 is a small microcontroller board originally based on the ATmega168, but now supplied with the 328.(datasheet), intended for use on breadboards and when space is at a premium. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, and a 16 MHz crystal oscillator. It can be programmed with the USB Serial adapter or other USB or RS232 to TTL serial adapter. The new Mini (revision 05) has a new package for the ATmega328, which enables all components to be on the top of the board. It also has an onboard reset button. The new version has the same pin configuration as revision 04.

Opto-isolated tachometer

“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

“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 …

Autonomous Lawn Mower without GPS RTK

“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 …

Digital Measuring Wheel

“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 …

Mini Filament Counter for 3d Printer

“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 …

How to use RYLR998 LORA module with Arduino

“Working with RYLR998 LORA and Arduino Pro Min 8v. In this tutorail I will show you how to program RYLR998 LORA radio modules from Reyax. How to connect them to Arduino. I will also create the code that will allow …

E-Paper Clock

“This project is an e-Paper clock and weather station that automatically sets itself (via GPS) and can be built to last about 6 months on 4 AAA batteries. It purposefully does not need any network connections for the sake of …

Electric Vehicle EV Charger

“I built my own 7.2kW EV charger and fitted it inside a Zappi enclosure. The 2 aims were simplicity and safety. This article documents the build. I wrote the Arduino software for it and all design files, software and …

Arduino DCC Decoder

“Modern model railroads are digitally controlled using a Digital Command Control (DCC) protocol similar to network packets. These data packets contain device address and instruction set that is embedded in the form of AC voltage and fed to train track …

Powering a ProMini logger for One Year on a Coin Cell

“The EDU build we released in 2020 provides remarkable flexibility for courses in environmental monitoring. However an instructor still needs to invest about five days ordering parts, testing components, and preparing kits for a 15-20 seat course being run remotely …
