In this project we are going to use one of the features of ATmega32A to adjust the brightness of 1Watt LED. The method that is used to adjust the speed of LED is PWM (Pulse Width Modulation). The method of PWM is explained here. Consider a simple circuit as shown in figure. Now if the switch in above …
This is an instruct able for making your own PWM (Pulse Width Modulated) fly back driver! The design is relatively simple and easy to make if you have basic electronic skills. In fact, you don’t even have to know how a transistor or a MOSFET works to make this. You only have to follow the …
fun with ATMega328 and rtl-sdr Yesterday came to my attention a project that turns the Raspberry Pi into a FM transmitter. It is totally awesome and you should check it out. While reading an article about it, I thought to check ATMega328 and its fast PWM mode I showed you in the previous article for electromagnetic …
The XCL206 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of 600mA is configured using only two capacitors connected externally. Operating voltage range is from 2.0V to 6.0V(XCL20xG:1.8V-6.0V). Output voltage is internally set in a …

Recently I had the problem some expensive components did overheat in my server rack. The ventilation was not optimal and I had to install additional fans. Because this rack is in my office and I like a quiet working place, the ventilation had to be as quiet as possible. First I thought about buying a …
This project uses the Arduino PWM Uno or other systems to realize a fully isolated analog output with a range of 0-5 volts or more, changing only the reference voltage. Introduction This project completes the series of my articles about the Arduino analog I/O with the aim to use it as a controller of small …
The MAX15062 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input voltage range. The converter delivers output currents up to 300mA at output voltages of 3.3V (MAX15062A) and 5V (MAX15062B). The device operates over the -40°C to +125°C temperature range and is available in a compact 8-pin (2mm × …
