Arduino Body Thermometer + LCD I2C
https://www.electronics-lab.com/arduino-thermometer-lcd-i2c/
This is a body thermometer using a thermistor sensor, Arduino and LCD display. I’ve decided to provide a funny Arduino concept thermometer in case its the middle of the night, pharmacies are not working, you are not feeling well and you want to check your body temperature. If you have Arduino by your side, this is […]
Mini Arduino Lux Meter
https://www.electronics-lab.com/mini-arduino-lux-meter/
Here is a nice build of a LUX meter using BH1750 sensor and a Nokia 5110 LCD. The meter is controlled by an Arduino Pro Mini and is powered by a Li-Ion battery. The LCD backlight is controlled according to environment light and there is graphing capability of the measured light intensity. That’s when I […]
Control ESP8266 over the internet
https://www.electronics-lab.com/control-esp8266-internet/
Here is a basic tutorial on how to control ESP8266 over the internet using two buttons on a browser window. The article goes through Arduino IDE configuration and example code is included. There are but a few things better than (succesfully) programming and using your Arduino. Surely one of those things is using your ESP8266 […]

Real time clock and temperature monitor with a DS3231 and a Color TFT
https://www.electronics-lab.com/real-time-clock-temperature-monitor-ds3231-color-tft/
In this video educ8s.tv is building a Real Time clock and temperature monitor with a big 3.2″ Color TFT display. They are using a DS3231 Real Time clock module to get the time, the date and the temperature. The heart of the project is the powerful Arduino Due board, which can drive the display and update […]
Arduino 433Mhz RF Wireless Data Transfer
https://www.electronics-lab.com/arduino-433mhz-rf-wireless-data-transfer/
Here is a tutorial on how to use 433MHz RF modules to send data from an Arduino to another. The example code transmits a message to the serial port of receiver. The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The […]
Arduino Voltmeter With OLED Display
https://www.electronics-lab.com/arduino-voltmeter-oled-display/
Konstantin Dimitrov has published an Arduino tutorial on how to make an voltmeter using SH1106 OLED display: I’m going to show you how to make a voltmeter with Arduino UNO, an OLED display, 2 resistors and 9 jumpers for less than 5 minutes. With it you will be able to measure voltage from 0 to 30V […]
ECG Arduino Shield
https://www.electronics-lab.com/ecg-shield-arduino/
This project is an Arduino shield able to measure ECG and respiration. The shield is equipped with a LCD display to show measured signal in real time. It’s based on ADS1292R ECG Front End from TI. Recently i made shield for arduino which can measure ECG, respiration, eventually after some changes in PCB and code, EEG and EMG. […]
Programming an ATtiny with Arduino board
https://www.electronics-lab.com/programming-attiny-arduino-board/
This detailed tutorial shows how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. It does, however, have some limitations relative to the ATmega328P on an Arduino Uno. There are […]
