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 one delivers the output voltage. I used an ...

The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...

This is accomplished by flashing LEDs to illuminate the droplets at just ... The top of the frame has eight nozzles, each fed by its own pump. An Arduino controls the pumps and the lights making ...

To the human eye, it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it doesn’t have enough outputs on its own to control all ...

especially for those getting started with Arduino. Using the USB on your computer is just so much easier when working with simple circuits like LEDs, PIR motion sensors, and other small loads.

Krejci’s tutorial video guides viewers on how to construct an infrared camera using an Arduino UNO, an infrared sensor AMG8833, and an 8×8 RGB LED display from SunFounder. Thermal cameras are ...

Both Photon and Electron can use Arduino "sketch" code or code written in Particle's own development tool. And Particle offers a cloud service that allows developers to scale up their devices to ...
