In this tutorial, I am going to use the ULN2003 IC to create a simple, inexpensive water level indicator.

Foldable Lamp Box - Night Light - reacts to sound and has adjustable brightness, USB port for charging, runs 24h on Battery - ATtiny85 processor - 25x WS2812 leds

This guide demonstrates how to craft a Star Wars game with the ESP8266, OLED Display, and Joystick Module

Dive into my hands-on review of the Elecrow All-in-One Starter Kit for Micro:bit. See what’s really inside the box, how fast you can get started (even if you’re a total beginner), what works great and what could be improved, and why this kit just might be the perfect solution for students, teachers, makers, or anyone curious about electronics and coding!

In this tutorial, I am going to unbox and show you guys how to program and use this cute little all-in-one kit from Elecrow using Arduino IDE.

This 4 digits 7 segments display module is controlled using 74HC595 Shift Register. The module uses a single standard common anode display

A basic robot motor driver brain, utilizing the Wemos D1 Mini.

This is a small (17.9 mm x 10.3 mm) breakout board for PixArt's PAA3905 optical flow sensor. It provides X-Y velocity at 126 Hz via Optical Flow and 35 x 35 pixel video camera at 18 Hz. There is a well-commented Arduino sketch showing how to use the device for navigation and frame grabbing. The frame grab rate is significantly improved over its predecessor, making for a practical low-resolution still imaging and video camera capability. Power usage is a modest 3.5 mA and the sensor can move in and out of shutdown mode quickly allowing flexible power management. The light level adjustment is automatic (although can still be done manually), streamlining sensor management. The sensor is smaller than its predecessors, with fewer pins making design and assembly easier. Light level sensitivity extends down to 5 lux. The frame grab occurs at a crisp ~15 Hz (56 milliseconds to complete), allowing low-resolution video imaging using the infrared-sensitive sensor element. Open source design!

I used this board to connect an Intel Compute Stick with mail hdmi connector to a portable 7-inch display with female hdmi input. You can use it as you wish. The clearance between the soldered connectors is 7 mm.

A project for automation, hobby and also learning.

Control headless devices using your uConsole via direct HDMI and USB connections for on-the-go troubleshooting and seamless device managemen.

The project represents an electronic switch actuated by the value of the light intensity that excites a photoresistor.
