How-to use PWM to Generate Analog Voltage in Digital Circuits
https://www.electronics-lab.com/use-pwm-generate-analog-voltage-digital-circuits/
Maurizio @ emcelettronica.com tipped us with his latest article on how to generate analog voltages using a microcontroller. Many times, designers are faced with the need of generating analogue or analog voltage levels in purely digital circuits. Although the market provides today a very broad range of dedicated digital-to-analogue converters, putting such a device in the […]
Getting Started with Atmel ATtiny10
https://www.electronics-lab.com/getting-started-atmel-attiny10/
Mahesh @ electronut.in show us how to program these tiny microcontrollers (ATtiny10) with Atmel Studio 7 and make an RGB led to light. I like Atmel tinyAVRs because they are tiny computers that I can (almost) wrap my head around. The Atmel ATtiny4/5/9/10 are the cheapest in the tinyAVR line, and they come in two packages […]
Temperature Display with NeoPixel Ring Color
https://www.electronics-lab.com/temperature-display-neopixel-ring-color/
This is an OLED temperature display based on ATmega328p along with a NeoPixel led ring to display different colors depending on temperature. This is a small temperature display using a OLED with a NeoPixel Ring around it using MQTT on a ESP8266 and sending data to the on board ATmega328p. It will cycle on a timer […]
Panelizing and Gerber Generation in Eagle
https://www.electronics-lab.com/panelizing-gerber-generation-eagle/
Shantam Raj @ hackster.io discuss about how to panelize PCBs and generate Gerbers on Eagle CAD. In this article he shares his experience and common mistake he made in the process. I have been working with Eagle for quite some time but never really got a PCB manufactured. almost all the time i used the […]
Reverse engineering the popular 555 timer chip
https://www.electronics-lab.com/reverse-engineering-popular-555-timer-chip/
Ken Shirriff wrote an article on reverse engineering the 555 timer chip, He writes: This article explains how the LMC555 timer chip works, from the tiny transistors and resistors on the silicon chip, to the functional units such as comparators and current mirrors that make it work. The popular 555 timer integrated circuit is said […]
Oscilloscope tips and tricks

Arthur Pini has compiled a list of tips and tricks for use on digital oscilloscopes. The article is separated on 3 parts. The first is “10 Tricks that extend oscilloscope usefulness” the second is “10 More tricks to extend oscilloscope usefulness” and the third on the link below. Modern digital oscilloscopes have a great many […]
SparkFun’s EAGLE resources
https://www.electronics-lab.com/sparkfuns-eagle-resources/
Sparkfun has compiled a list of resources about everything you need to design for manufacture an electronic product. Let’s be frank: We’ve made a lot of mistakes over the years. In the ongoing pursuit of better-designed PCBs, we’ve dealt with tons of screw-ups, from boards with ill-arranged traces to boards with…no traces at all, actually, […]
Using BMP180 for temperature, pressure and altitude measurements
https://www.electronics-lab.com/using-bmp180-temperature-pressure-altitude-measurements/
Raj from Embedded Lab has posted a comprehensive tutorial on how to use BMP180 for temperature, pressure, and altitude measurements. The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board […]
Temperature controlled fan
https://www.electronics-lab.com/temperature-controlled-fan/
Lukas Fassler from Soldernerd has written up documentation on his DIY fan controller project: I’m currently mainly working on my new anemometer design but once in a while I get distracted. For example when my Keysight E3645A lab power supply was making so much noise that I could hardly concentrate. That’s when the idea of […]
