AVR vs PIC: The case of the candle


https://www.electronics-lab.com/avr-vs-pic-case-candle/

A self-igniting candle implemented using AVR and PIC microcontrollers. This project has two variations, one using an ATTiny25, the other using a PIC12LF1822. In a series of minimalistic devices, this electronic candle periodically measures ambient light levels. Once it detects nightfall, it self-ignites and burns for three hours, flickering as a candle does. The flicker […]

Dark Sensitive Switch – LED Light


https://www.electronics-lab.com/dark-sensitive-switch-led-light/

Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point.  The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project can also be considered for use in energy […]

Magnetic Field Measurement Using HMC5883 and Arduino Nano


https://www.electronics-lab.com/magnetic-field-measurement-using-hmc5883-arduino-nano/

In this tutorial we are going to learn the detailed working of HMC5883 with arduino nano. The HMC5883is a digital compass designed for low-field magnetic sensing.This device has a wide magnetic field range of +/-8 Oe, and an output rate of 160 Hz. The HMC5883 sensor includes automatic degaussing strap drivers, offset cancellation, and a […]

How to Scroll a single LCD line – Arduino


https://www.electronics-lab.com/scroll-single-lcd-line/

R Jordan Kreindler show us how to scroll a single line on a LCD display. The Liquid Crystal Library has two quite useful functions scrollDisplayLeft() and scrollDisplayRight(). These functions scroll the whole display. That is, they scroll both lines on a 1602 LCD and all four lines on a 2004 LCD. What we often need […]

Fuel-gauge ICs help prevent battery clones


https://www.electronics-lab.com/fuel-gauge-ics-help-prevent-battery-clones/

Maxim’s family of ModelGauge m5 standalone fuel gauges provides SHA-256 authentication with a 160-bit secret key to make it harder to clone battery packs. The ICs also implement the ModelGauge m5 algorithm, which converts raw measurements of battery voltage, current, and temperature into accurate state-of-charge (SOC%), absolute capacity (mAhr), time-to-empty, and time-to-full readings. by Susan […]
