4-20 mA current output for Arduino Uno
https://www.electronics-lab.com/4-20-ma-current-output-arduino-uno/
Giovanni Carrera writes: The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller ATmega328 and numerous other chips, such as the PIC. One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino.” 4-20 mA […]
Tiny Lisp Computer using ATmega328
https://www.electronics-lab.com/tiny-lisp-computer/
The Tiny Lisp Computer is a self-contained computer programmed in Lisp. Some programming examples are included in the author’s website. This article describes a self-contained computer with its own display and keyboard, based on an ATmega328, that you can program in Lisp. You can use it to run programs that interface to components such as […]

$2 Arduino – ATMEGA328 as a stand-alone
https://www.electronics-lab.com/2-arduino-atmega328-as-a-stand-alone/
In this tutorial you will learn how to use ATMEGA328 microcontroller as standalone Arduino. This way you can minify your next arduino project. They cost only 2 bucks, can do the same as your Arduino and make your projects extremely small. We will cover the pin layout, how to make it ready for the Arduino […]
ATMEGA328 based Weather Station
https://www.electronics-lab.com/atmega328-weather-station/
Vlad @ denialmedia.ca has build a solar powered weather station based on ATMega328 microcontroller that is able to measure temperature, a humidity, and UV radiation and it uploads measurement on WeatherUnderground network. The data are send to the air using a 433MHz link. The sensors used are DHT22, ML8511, BMP180 and a TP4056 charger IC is used to […]
MAX038 Function generator
https://www.electronics-lab.com/max038-function-generator/
Milen @ instructables.com has designed a Function Generator based on the popular MAX038 and is controlled by ATMega328PU. Signal characteristics are displayed on a LCD screen. The digital features of the function generator were performed by one Atmega328 chip. Its functions are the following: controls the frequency range selection controls the signal type (sine, rectangular, […]
Staff with Click Sound and Obstacle Alarm
https://www.electronics-lab.com/staff-with-click-sound-and-obstacle-alarm/
People who are visually impaired usually use a staff to guide them as they walk. They tap with their staff to know if an obstacle is present around. Others use the echolocation technique. They produce a clicking sound through their tongue, foot, and fingers and through this they detect objects from their surrounding by sensing […]
ATMEGA328 Component Tester
https://www.electronics-lab.com/component-tester-2/
baweja_akshay @ instructables.com has build a ATMEGA328 component tester that is able to test Resistors, Capacitors, Inductors, BJT, FET, Thyristors and more. Coming upon COMPONENT TESTER so it can test almost everything, obviously not the power components because they require more current and power which our AVR Microcontroller couldn’t handle !! Oh yeah, I forgot to […]
Advanced Datalogger with ATMEGA328, BMP180, DHT22, BH1750 and sd card
https://www.electronics-lab.com/advanced-datalogger-with-atmega328-bmp180-dht22-bh1750-and-sd-card/
educ8s.tv has published another great Arduino project. It’s a ATMega328 based datalogger able to record temperature, humidity, barometric pressure and light to a SD card. In this video we build an Advanced Data Logger with Arduino. We use a DHT22 temperature and Humidity Sensor, a Bmp180 barometric pressure sensor and a BH1750 light sensor. The […]
