Connect Arduino pin9 to CS of 8×8 LED Matrix; Connect Arduino pin10 to CLK of 8×8 LED Matrix; Connect an external 5VDC (1A) to VCC of 8×8 LED Matrix; Connect external 5VDC supply’s GND, to the GND of ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...

The modules are based on the QS30-1 Nixie tube capable of displaying the digits 0 through 9, and include an RGB LED behind the tube for some nice additional illumination.

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...
