1Hz to 30KHz Wave Generator Using Arduino


https://www.electronics-lab.com/1hz-30khz-wave-generator-using-arduino/

Wave generator is one of the most needed tools in our electronics labs, you can buy a fully functional ready made one or make a simple one using your Arduino. Joekutz over Hackaday.io created a simple wave generator using Arduino powered from 9V battery and produces amplified and non amplified signals. This generator uses the […]

How to control Arduino board using an Android phone


https://www.electronics-lab.com/control-arduino-board-using-android-phone/

Kerimil, user on Arduino Forum, submitted his project which focuses on establishing communication between an Arduino board and an android mobile using bluetooth: The idea is to gain access to hardware on Android devices (accelerometers, gyro, wifi connectivity, gps, GPRS, touchscreen, text to speech and speech to text) and/or use it to relay data to […]

Filtering Noisy Arduino Measurements


https://www.electronics-lab.com/filtering-noisy-arduino-measurements/

Paul Martinsen @ megunolink.com discuss about noise in analog input of arduino and how to filter it. He examines 3 filtering algorithms: Averaging, Running average, Exponential filter and provides the code to achieve that. Measurements from the real world often contain noise. Loosely speaking, noise is just the part of the signal you didn’t want. […]

The IoT Project Builder “myDevices” Has Added Arduino Support


https://www.electronics-lab.com/iot-project-builder-mydevices-added-arduino-support/

“myDevices”, creators of IoT platform Cayenne, announced in a press release a partnership with Arduino to integrate Arduino support in their system. The partnership seems to be with Arduino SRL not with Arduino LLC. The currently supported Arduino boards, beside variety of sensors and actuators, are: Arduino Due Arduino Leonardo Arduino Mega Arduino Nano Arduino […]

Arduino Geiger–Müller counter with LCD display


https://www.electronics-lab.com/arduino-geiger-muller-counter-lcd-display/

Bob tipped us with his latest project. It’s a custom Arduino shield able to communicate with a Geiger-Muller counter and display data on a LCD display. The data are displayed in two layouts: bar graph of the pulses in one minute interval and histogram of the gathered data. In the previous posts I’ve described a […]

Simple Arduino Radio with TEA5767


https://www.electronics-lab.com/simple-arduino-radio/

AxelP6 @ instructables.com has uploaded a new tutorial on how to make a simple arduino radio based on 2.2″ TFT ILI9225 controller, TEA5767 breakout board and Arduino MEGA2560. The radio can play a list of predefined stations and can’t scan through them. So, I was searching for a tutorial to create a simple Radio with […]

Sunburn Monitor – A UV monitor


https://www.electronics-lab.com/sunburn-monitor-sound-base-indication-uv-monitor/

Sunburn Monitor is a UV monitor with sound-based indication. It calculates the max sun exposure before sunburn based on your skin type. The project was published over hackaday.io by [Quarterturn]. It’s based around SI1132 light sensor from Silicon Labs. SI1132 is a UV index and ambient light sensor with I2C interface and it’s available in […]

An isolated analog input for Arduino


https://www.electronics-lab.com/isolated-analog-input-arduino/

Giovanni Carrera designed a circuit that accepts input voltage from about 20mV to 5V or a current of 4 to 20 mA and converts it to a isolated frequency signal. A voltage to frequency converter can realize an opto-isolated analog input for Arduino or other microcontroller systems. This circuit is particularly suitable for industrial control […]

How to Measure LUX With Arduino


https://www.electronics-lab.com/measure-lux-arduino/

In this tutorial codebender_cc uses the Adafruit TSL2561 sensor to measure LUX with Arduino. The TSL2561 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for […]
