Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement. It's not complicated, but the sheer number of colors ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will… ...

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board ...

If you are using Arduino Mini Pro, UNO or similar, pay attention to the pin 13 and the use of on internal pull-up resistor. This pin has a LED and a resistor connected on the board.

The AL5887 LED driver from Diodes is supplied in a 52-pin wettable QFN package, with exposed pad for better heat dissipation, and is available at $1.70 in 1,000 piece quantities.

ACircuit Diagram to Interface LED MAtrix display with Arduino Now that we have completely understood how a MAX7219 LED Dot Matrix Display Module works, we can connect all the required wires to the ...

As you can see, apart from the AT24C256 chip (U1), the module holds one power indicator LED (D1) with its series resistor (R1), four 2-way jumper pins (J1-J2-J3-J4), two I 2 C pull-up resistors (R2-R3 ...

This is the second which fully supports the PS2 Keyboard Protocol, even allowing you control of keyboard LEDs (some have 4 LEDs) and changing settings.. The PS2 Keyboard interface is still needed for ...

If you've ever dreamed of becoming a coder or programmer but don't know where to start, this bundle may be for you. The Ultimate Arduino Coding Power Course Bundle brings you everything you need ...

3. LED (LED2), which is connected to digital pin D10 of Arduino through current-limiting resistor R4. The Arduino Nano board and RF RX1 module get power supply from central storage system computer ...
