LED Gumball Machine

Every electrical project starts with a circuit. Don't know what a circuit is? We're here to help.

An overview of the inner workings of a battery and how it was invented.

Dive into the basics of Radio Frequency Identification (RFID) technology.

Let's have some fun with LEDs! We'll explore LEDs once again with the SparkFun RedBoard Qwiic, making cool effects, and putting those effects to work using a sensor.

A quickstart guide for the micro:bit educator lab pack.

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.

How to use and re-program the OpenLog Artemis, an open source datalogger. The OLA comes preprogrammed to automatically log data. The OLA can also record serial data, analog voltages, or readings from external Qwiic-enabled I2C devices. Some of these Qwiic-enabled devices include GPS/GNSS modules, pressure, altitude, humidity, temperature, air quality, environment, distance, and weight sensors.

Using WiFi to send sensor data from an ESP32 to a WiFi network and be able to read it from an IoT Dashboard from anywhere in the world.
