Monolithic linear battery charger operates from inputs up to 60V
https://www.electronics-lab.com/monolithic-linear-battery-charger-operates-from-inputs-up-to-60v/
Joshua Yee @ edn.com discuss about LTC4079 250mA Linear Li-Ion Charger IC that can be powered with voltages up to 60V. For charging relatively low capacity batteries, or maintenance charging backup and keep-alive batteries, linear topology battery chargers are valued for their compact footprints, simplicity and affordability. Even so, there is a dearth of linear […]
LT8391 – 60V Synchronous 4-Switch Buck-Boost LED Controller
https://www.electronics-lab.com/lt8391-60v-synchronous-4-switch-buck-boost-led-controller/
The LT8391 is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltage above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 150kHz to 650kHz fixed frequency operation, or internal ±15% triangle spread spectrum operation for low EMI. With 4V to […]
Wireless communication between two Arduinos using inexpensive RF modules
https://www.electronics-lab.com/wireless-communication-between-two-arduinos-using-inexpensive-rf-modules/
Raj from Embedded Lab has posted a new article exploring an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules. He used a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless temperature and humidity monitor. Wireless communication between two Arduinos using inexpensive […]
AC PWM dimmer for Arduino
https://www.electronics-lab.com/ac-pwm-dimmer-for-arduino/
diy_bloke @ instructables.com has designed an AC PWM dimmer for Arduino: Over 3 years ago, I published a simpel TRIAC AC dimmer for the arduino. That proved to be a very popular design. Yet in spite of the simplicity of the circuit the software needed was a bit complicated as it needed to keep track of […]
$2 Arduino – ATMEGA328 as a stand-alone
https://www.electronics-lab.com/2-arduino-atmega328-as-a-stand-alone/
In this tutorial you will learn how to use ATMEGA328 microcontroller as standalone Arduino. This way you can minify your next arduino project. They cost only 2 bucks, can do the same as your Arduino and make your projects extremely small. We will cover the pin layout, how to make it ready for the Arduino […]
BooSTick – small AA voltage booster
https://www.electronics-lab.com/boostick-small-aa-voltage-booster/
A single AA battery provides voltages of 5V or 3.3V for hardware prototyping. This tiny board allows you to bring the power to your project, and not the other way around. Bring your micro to the sensor without running wires! A single AA battery is used to provide breadboard power of 5V or 3.3V (or […]
5V to 12V Step Up DC-DC Converter
https://www.electronics-lab.com/5v-to-12v-step-up-dc-dc-converter/
Step up DC-DC converter is based on LM2577-ADJ IC, this project provides 12V output using 5V input, maximum output load 800mA. The LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up (boost), fly back, and forward converter switching regulators. The device is available in three different output voltage […]

MMC3630KJ – Magnetic sensor in BGA package
https://www.electronics-lab.com/mmc3630kj-magnetic-sensor-in-bga-package/
MEMSIC has announced the MMC3630KJ magnetometer that integrates a monolithic 3-axis AMR (anisotropic magnetoresistive) sensor and a signal conditioning ASIC into a 1.2 × 1.2 × 0.5-mm BGA package. According to MEMSIC, devices in the series offer the ability to deliver a magnetic sensitivity in a range of ±30 Gauss and achieve a noise level that is […]
Arduino controlled Triac light dimmer
https://www.electronics-lab.com/arduino-controlled-light-dimmer/
diy_bloke @ instructables.com has build an arduino controlled triac light dimmer and describes the circuit and software used to achieve that. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino: just limiting the current through e.g. a transistor is not really possible due to the large […]
