Sensirion Tiny sensor hones temperature accuracy


https://www.electronics-lab.com/sensirion-tiny-sensor-hones-temperature-accuracy/

Housed in a tiny 8-pin DFN package, the STS31 digital temperature sensor from Sensirion guarantees accuracy to within ±0.3°C over a temperature range of -40°C to +90°C. A low-cost version, the STS30 achieves the same accuracy over a temperature range of 0°C to +65°C. Both devices are only 0.9 mm high and occupy a footprint […]

Hardware serial port monitor over WiFi


https://www.electronics-lab.com/hardware-serial-port-monitor-with-wifi/

This tutorial shows how to connect Arduino to the TX line (of a router, RPI) and display serial data on smartphone over WiFi. Arduino listens for serial port communication on its hardware serial port. Then it sends every received line of data trough software serial port to ESP8266. ESP8266 puts every received line of data […]

DIY Wearable Posture Sensor


https://www.electronics-lab.com/diy-wearable-posture-sensor/

With the help of this wearable device you can improve your posture as it will remind you whenever you slouch. The device is based on ADXL335 accelerometer and Attiny85 microcontroller and a vibration motor will get you notified. Posture sensors/monitors have been a recurring theme on this blog. They are supposed to remind you of your posture […]

Wifi Home Thermostat


https://www.electronics-lab.com/web-enabled-home-thermostat/

asheville makers @ instructables.com has posted a Wifi enabled thermostat that can be programmed via a touch screen display or via the internet. This Instructable explains about how I built WiFi enabled thermostats for my home. The thermostats are programmable with 6 different time periods during the day, although increasing that to any arbitrary number would […]

4A Bipolar Stepper Motor Driver Based on LV8727E


https://www.electronics-lab.com/4a-bipolar-stepper-motor-driver-based-on-lv8727e/

The Project is based on LV8727E IC from ON Semiconductor. The LV8727 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can provide eight ways of micro step resolution of 1/2, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20, and can drive simply by the step input. This Bipolar Driver works with supply […]

PWM dimmer for RGB LED


https://www.electronics-lab.com/pwm-dimmer-for-rgb-led/

Lukas Fassler has designed and built a PWM dimmer for RGB LED: In my last post I’ve described the design and construction of my LED dimmer project. This project here is similar but a bit more involved. It controls RGB LEDs so it can not only change the brightness but also the color of the […]

Arduino DS18B20 Thermometer on iOS or Android


https://www.electronics-lab.com/arduino-ds18b20-thermometer-on-ios-or-android/

maroelawerner @ instructables.com has a tutorial on how to display temperature data on an Android or iOS device using Arduino and Blynk app. In this Instructable I am going to attempt to show you how to put together a little project to use the Blynk app (optainable at http://www.blynk.cc/) to display the temperature remotely on a […]

How to Implement Embedded Ethernet


https://www.electronics-lab.com/how-to-implement-embedded-ethernet/

Maurizio @ dev.emcelettronica.com has tipped us with his latest article on how to implement embedded Ethernet on any mcu. The article shows the basic principle of Ethernet implementation. Usually We need embedded systems inside devices, particularly the so-called intelligent devices, to communicate with a command/control/administrative center. Typical such situations could be a remote security camera […]

Geiger–Müller counter that works with Arduino


https://www.electronics-lab.com/geiger-muller-counter-that-works-with-arduino/

Bob @ robertgawron.blogspot.com has posted a Geiger-Muller project that can be used with Arduino or any other microcontroller board. The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of […]
