Today’s PyroElectro tutorial will show you how to use popular RF Modules to create a wireless link between two PIC microcontrollers. The article explains the theory, gives all schematic details and the software project files. The low cost and ease of use make these RF Modules a good choice for any project.

This week’s PyroElectro tutorial explores the high speeds of I²C communication and how to create an interface using the PIC uController. I²C is very popular as only 3 wires are required for highspeed multi-device communication. An example design to communicate with an I²C flash memory device is used in the tutorial to get you started.

Stepper motors are a very powerful, yet accurate type of motor. The ability to ‘step’ through motion instead of to run uncontrollably like dc motors do is a great advantage. This write-up shows you how to use an L298 to control a stepper motor.

If you’ve ever used a music playing utility on a pc you’ll notice they always have a cool little display of either the audio frequency spectrum or the actual audio amplitude wave. The Music Equalizer Display created in this tutorial outputs the latter using a standard 10 LED bar.

Previously we explored DC motor control using the LMD18245. Now, looking forward we’ll use a method for even better motor control using the infamous L298. Specifically the L298HN (makes things even easier), Check It Out!
