This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...

Here, for demonstration, three different color LEDs (Red, Green and Blue) are used. You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed.

The Julia programming language is a horrible fit for a no-frills microcontroller like the ATMega328p that lies within the classic Arduino, but that didn’t stop [Sukera] from trying, and succe… ...

A Light Emitting Diode (LED) should light up once the Arduino has power and after a second or so, an LED on the board should start slowly blinking. The image below points out these LEDs on the board.

The Arduino Micro is closely related to the Leonardo, with some small difference. Each led in both is connected in series with a 1kΩ resistor to limit current. One Leonard-Micro difference is with the ...

Instructables user vatosupreme created the effect in the above video by constructing the eyes using ping-pong balls, LEDs, and wooden poles and connecting those LEDs to a control board built with ...
