Pulse Operations with the 16-Bit Micro Experimenter

Time to add more tools to your Experimenter board! This month, we’ll look at the digital pulse capture and generation capabilities.


Thermoelectric Powered Sunflowers

This summer, create a nice evening ambience using a thermoelectric generator that gets its power from the sun.

Make the Bike Blinker Plus

As a cyclist, not only will you be more visible at night with this handy gadget that fits into your helmet, you’ll also know the air temperature!

Build the WatchPuppy

by Jim Sky

Keep your unattended computers working in the event of a software crash with this device that can reboot your modem, router, or other networking device when needed. You can also use the WatchPuppy as a remote monitoring device for temperature or voltages. This is an open-ended project that can be expanded to meet your specific needs.

Taking USB Downstream
Up to this point, we’ve been working our USB device magic on an upstream connection to a USB host. The time has come to take on USB host responsibilities and originate a downstream connection from the Type A USB connector of a USB host we will design and assemble.

Crystal Clock Oscillators: The Heart of All Communications Products
If you look inside any electronic product today, there are a few circuits and components that are common to all of them. For example, every product contains at least one microcontroller that runs it. Another circuit that you will see — especially in communications products — is a crystal oscillator or clock. This circuit generates precise timing signals that control everything else — including that microcontroller. In communications gear like radios, that crystal is the source of the exact opera
