PCB Christmas tree
https://www.electronics-lab.com/pcb-christmas-tree/
Well, Christmas may over but we think you may take a look at this well designed PCB Christmas tree and why not consider building it for the next year. Since I already have an Arduino, and I felt pretty comfortable with it, I decided to use it to control the LEDs. However a full Arduino […]
Designing and Building a binary clock
https://www.electronics-lab.com/designing-and-building-a-binary-clock/
Parker Dillmann @ macrofab.com has designed a wrist LED binary clock based on PIC16F527 Microchip mcu. The Macro Watch stemmed from those constraints. I picked the PIC16F527 microcontroller by Microchip to be the core of the watch because it was the cheapest MCU I could find that had enough I/O and I knew at least […]
Speech Recognition with Arduino and BitVoicer Server
https://www.electronics-lab.com/speech-recognition-with-arduino-and-bitvoicer-server/
leandro4b @ instructables.com shows us how to control some LED using your voice. He used an Arduino board and BitVoicer server to make this happen. In this Instructable I am going to show how to use an Arduino board and BitVoicer Server to control a few LEDs with voice commands. I will be using the […]

Hi-glow LED’s providing enough flashing light to attract your attention. Can be used as warning light. Specifications Supply input 12 V @ 35 mA (6 to 15V Dc […]
Pixie – 3W chainable smart LED Pixel
https://www.electronics-lab.com/pixie-3w-chainable-smart-led-pixel/
Ytai Ben-Tsvi @ ytai-mer.blogspot.com build a PIC based 3W LED Driver that is chainable. He writes: LED Pixel: The Pixie is a color LED module, allowing an external controller to change its color and brightness dynamically. Chainable: The module is designed so that you can chain many of them and control each one individually. If you […]
Disco Lights with IC555
https://www.electronics-lab.com/disco-lights-with-ic555/
This is a simple 555 timer IC circuit that is able to power two strings of LEDs alternative. Disco lights are mostly used in decoration made with colourful LEDs. For begginners, this is a compact circuit using a single chip IC. IC555 is connected here to form a multivibrator. The blinking speed can be easily […]
