“This is a simple inverter circuit or driver provides power for different types of LEDs (eg- white LED, blue LED, UV LED, but also any other LED) from 1.2 Volt or 3.7 Volt single cell or Lithium-ion battery …
“The LED Cube is nothing but a 3-dimensional array of LEDs to light up in different forms and patterns. It’s an interesting project to learn or better your Soldering, Circuit Designing, 3D Printing, and Programming skills. Though I would …
“A cheap beam break sensor utilising a reflector panel instead of a transmitter / receiver setup. Capable of handling long distances. Specific parts list: I found These LEDs with a half-angle of 5 degrees able to emit 100mA of power. They …
“Zener Diode Tester is controlled by Arduino Nano. Tester measure breakdown Zener voltage for diodes from 1.8V to 48V. Dissipation power of measured diodes could be from 250mW to a few Watts. Measuring is simple, just connect diode and …
“Controlling a robotic arm to pick up and drop objects is difficult enough, without IoT it would be near impossible to do this remotely. Story Introduction I really wanted to try was designing a robotic arm completely from scratch. There …
“So you’ve built a robot. Let’s say that it’s your second one. Typically, we buy a complete one as a kit, for instance, maybe a Smart Video Car from Sunfounder. We had fun building it, rolling it …
“Hello Guys, In this instructable, I am going to show you how you can convert your old or broken led bulb into a smartphone-controlled colour changing smart led bulb. So let’s get started :) Here’s the complete tutorial and …
“I do not know why I especially liked to do some projects about lighting and sound. Here is one of LED projects, as called “8x16x8 RED GREEN CUBE- HANDWRITTEN CLOCK”, that actually made me very excited. And I hope you …
“A Joule Thief is a simple voltage booster circuit. It can increase the voltage of a power source by changing the constant low voltage signal into a series of rapid pulses at a higher voltage. You most commonly see this …
“An SR latch is a kind of circuit that is called “bistable.” Bistable circuits have two stable states, hence the name BI-stable. One of the simpler versions of this kind of circuit is the SR latch, which stands for …
