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 […]
