In this tutorial you will learn how to build a basic development board for Attiny2313 microcontrollers. Did you ever want to make your own development board with microcontroller and you didn´t know how .In this instructable I will show you how to make it.All you need is knowledge in...

This tutorial shows how to interface DC motors using L293D motor driver IC and Arduino. Controlling DC motors with Arduino and L293 -...

Loren Siebert @ ti.com discuss about how to interface signals that have a reference voltage that isn't 0V while preserving the DC information. Many signal paths are direct current (DC)-coupled, and this can lead to challenges when different portions of the signal path require...

Noela and Miguel from Area0x33 made a really helpful tool on hackaday.io. They designed a fully open source hardware USB stick to store your username/password pairs on. MemType uses Atmel ATtiny85 MCU and V-USB to do the communication over USB. V-USB is software-only implementation...

When you see some board designs, especially ones with high speed signals or differential pair signals, then you will notice a lot of zigzag/meander lines on PCB. If you’re wondering whether you can do differential pair routing, then the answer is simply yes by using Meander...

James Lewis from Kemet has made a presentation to address some of misconceptions about capacitors like how you should de-rate capacitors. James said that de-rating depends on the chemistry and configuration of a particularly capacitor.  So he started by asking a question: Should...

Ahmad Al-Shalabi and Bassma Karbouj show us how to control a DC fan using easy to find components. The fan works when temperature reach into pre-specified threshold. The purpose of this project is creating a cooling system by controlling in a DC fan in a simple way without using...

Vasily Ivanenko build some discrete chip oscillators with 74HC series logic gates and tests them on his oscilloscope. He writes: In numerous RF synthesizer chips lies an inverter with input and output pins for making a reference crystal oscillator clock. I built some discrete chip...
