Visuino – visual programming environment for Arduino
https://www.electronics-lab.com/visuino-visual-programming-environment-for-arduino/
Visuino is the latest software developed by Mitov Software which allows you to program your Arduino boards using a graphical interface. So far only the official boards are supported but more will come. Using Visuino you can easily create complex programs using drag and drop interface without the need to become expert in programming. Check […]
MIDI to USB Adapter with Teensy
https://www.electronics-lab.com/midi-to-usb-adapter-with-teensy-lc/
Joonas Pihlajamaa wanted to connect his keyboard to his Macbook and for that reason he build a MIDI to USB interface using Teensy board, an optocoupler and some resistors. Thankfully, I had a MIDI connector and a high-speed optocoupler at hand, and with these I could implement a MIDI in rather easily. After some investigation […]

by Harry Baggen @ elektormagazine.com STMicroelectronics has launched their second-generation distance senor VL53L0, which is based on STM’s popular FlightSense technology. This sensor is suitable for use in smartphones and tablets to make quick distance measurements for an integrated camera, but it can also be used in robots, drones and wearables. Despite its compact dimension of […]
10 steps to selecting a microcontroller
https://www.electronics-lab.com/10-steps-to-selecting-a-microcontroller-2/
Jacob Beningo @ edn.com discuss on how to select the right mcu for your next project based on hardware and software architecture. Selecting the right microcontroller for a product can be a daunting task. Not only are there a number of technical features to consider, there are also business case issues such as cost and lead-times […]
Unipolar Stepper Motor Driver Circuit
https://www.electronics-lab.com/unipolar-stepper-motor-driver-circuit/
This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of General Purpose I/O (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications. It consists of a 4-bit configuration register […]
Using a $2 DS3231 RTC & AT24C32 EEprom from eBay
https://www.electronics-lab.com/using-a-2-ds3231-rtc-at24c32-eeprom-from-ebay/
Edward Mallon @ edwardmallon.wordpress.com gives us a detailed explanation about cheap RTC modules found on ebay and other places. I built the first few beta units with the DS3231 Chronodot from Macetech (about $18 each), but I kept on stumbling across cheap RTC modules on eBay, Amazon, etc. and I eventually bought a couple to try […]
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 […]
Home Thermostat With Arduino and LCD
https://www.electronics-lab.com/home-thermostat-with-arduino-and-lcd/
ArisK3 @ instructables.com decided to replace his home thermostat with a DIY one so he build an Arduino based thermostat with big character LCD. Replacing a standard thermostat (SIEMENS-RAA30 16GR) with a self made, arduino-based, big LCD screen is a fun project. Home Thermostat With Arduino and LCD – [Link]
Arduino Voltmeter Prototype
https://www.electronics-lab.com/arduino-voltmeter-prototype/
Proto G @ instructables.com has build an Arduino based digital voltmeter that is able to measure up to 30V and it’s using an OLED LCD display. In this instructable, I’ll show you how to make a simple arduino voltmeter. It can measure voltages in excess of 30VDC depending on how you configure it. The smaller […]
