by DIYmasters @ instructables.com: Hi everyone, this is my first Instructable, and in it, I'll be showing you how to fade an LED with an Arduino Uno , 2 Jumper wires, 1 Resistor, and a breadboard. LED Fade using Arduino Uno -...

This instructable is about making battery shield for Arduino. Arduino Battery Shield -...

Opto-Isolated 4-Channel Triac Board (R) is used for fast switching applications. Ideal for switching mains circuits, lights, appliances and small load. Each circuit is effectively isolated with opto-isolators on each channel, TTL inputs control each channel. Trigger input 2-12...

by Lyle Russell Williams: You can use three discrete transistors to build an operational amplifier with an open-loop gain greater than 1 million (Figure 1). You bias the output at approximately one-half the supply voltage using the combined voltage drops across zener diode D1, the...

In telecommunications, ideal RF switches require low insertion loss, high isolation and linearity. The IDT F2912 is a single-pole-double throw RF switch capable of having low insertion of loss of 0.4dB at 1GHz and a RF1 to RF2 Isolation of 74dB at 1GHz with extended temperature of...

An update on LuckyResistor’s data logger project: Just to let you know the deluxe version of the data logger is almost done. The hardware is ready and tested – currently I finish the menu based software for the data logger. Menu based control with 5 capacitive inputs Record,...
