Today we are working with the TMP117, a precision temperature sensor with an accuracy within 0.1 degrees Celsius.
We’ll see how this sensor, on a module from Adafruit, can be easily connected to a microcontroller to build a super-accurate thermometer. We’ll even put together a WiFi thermometer with an OLED display.

Looking for a power supply for your next project? How about one that can deliver up to 20 volt’s at 5 amps?
USB-PD is a technology that permits USB power supplies and chargers to deliver multiple voltages and currents. Today we wil learn how to use USB-PD in our projects.
Why use a mouse, keyboard and monitor with your Raspberry Pi when you don’t have to? Learn to enable and use Remote Access on the Raspberry Pi and control your little boards from anywhere in the world!
We wil examine three remote access methods you can use – SSH, VNC and Raspberry Pi Connect.
Bluetooth Classic and Bluetooth Low Energy (BLE) and short-range communications systems that connect computers, mobile devices, peripherals and sensors. You probably have several Bluetooth devices in your home, and with the ESP32 you can connect to all of them.
The ESP32 is Bluetooth-capable, but not every ESP32 wil work with every version of Bluetooth.
Join me today to learn all about Bluetooth and how to work with it on the ESP32.
The multimeter is the most essential piece of test equipment you can own. It’s ability to measure current, voltage , resistance and many more parameters makes it indispensable for the technician or experimenter.
Today we will see how to use a multimeter to measure just about everything.
A complete guide to the tools you need to work with electronics. Everything from screwdrivers and pliers to soldering and crimping equipment.
This guide is for experimenters, creators and service folks of all levels. Check it out and pick up a few new tools for your own workshop!
LoRa is a Long Range radio system that is inexpensive and free to use. You can achieve great distances with a simple wire antenna, and LoRa is very easy to use.
Today we will see how LoRa works and how we can use LoRa modules to communicate between Arduino, ESP32 and Raspberry Pi Pico boards.
We’ll also build a data-gathering system that you can easily expand upon.
