The world is analog. Use analog to digital conversion to help digital devices interpret the world.

How to interpret hex numbers, and how to convert them to/from decimal and binary.

A brief history of how ASCII came to be, how it's useful to computers, and some helpful tables to convert numbers to characters.

LTspice is a high performance SPICE simulator, schematic capture and waveform viewer with an impressive library of passive devices. Over 1000 models are included in the download but you can also add third party models.

The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.

A Hookup Guide to get started using the SHTC3 breakout.

Time for racing, let's make a wireless timing device using ESP32 wireless communication.

In this tutorial, we will cover how to calibrate your Qwiic Optical Tracking Odometry Sensor (or "OTOS") with Arduino and Python Examples.
