Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

In my case I have used only 3 x 330Ω resistors, 3 leds and a TSOP4838 IR receiver module. You must check the datasheet before use the IR module to see which pins connect to the power supply and which ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Instead of the relative horror of driving 40 LEDs with a single Arduino, ... To actually power and control the entire circuit, [Martyn] used an Arduino loaded up with a program based ...

Here is ‘blink’ modified to work TXLED and RXLED as well as LED-BUILTIN. int RXLED = 17; // The RX LED has a defined Arduino pin int TXLED = 30; // The TX LED has a defined Arduino pin // the setup ...

Power Supply (5-12V) and External Battery connector The UDOO has been in development for more than a year, and the team says it is "80 percent ready" to deliver the final product.

When you read “Arduino wristwatch”, ... I had thought a coin cell wouldn’t be sufficient to power, in my case, up to 24 LEDs simultaneously, so I went with a small LiPo. Report comment. Reply.

Fancy making a cool looking magnetic levitating lamp? Check out this Arduino Nano-based project that combines a magnet and LEDs. What's that you say? The lamp is not levitating, it's being held up?

To be eligible for prizes, selected challengers must post at least five updates on the element14 Community and a final project blog showcasing their build and ...
