Getting started with electronics can be a daunting task. It can seem like there is just too much to learn before you would be able to make anything fun. Thankfully Adafruit has you covered. We have curated a bunch of guides that we think should help get you started on your electronics journey. Learn the basics like how to solder, or what individual electronic components do and how they work.
Always on the computer with no time to water your plants? Build an internet-enabled planter to send notifications over a Slack or Discord channel when it needs water.
In this project, you’ll build an IoT planter using the Raspberry Pi Pico RP2040 and the STEMMA Soil Sensor. Then, you’ll add an AirLift breakout board to connect it to the internet and send sensor data to Adafruit IO. Finally, you’ll use Adafruit IO’s reactive trigger features to send webhook notifications about your planter to a Discord or Slack server.
For this project, you can use Slack or Discord. While it is possible to do both, this guide won’t go into that.
ALS Deep Cut
With so many guides on the Adafruit Learning System, some amazing guides of years past get buried and lost. ALS Deep Cuts brings these guides back up to the surface. This week’s guide is from back in 2014.
A circuit can live in many forms – most of them being ‘board’ forms. Likely the two most important for DIYers are the easily-modifiable breadboard and resilient yet still versatile perfboard. Taking a design from schematic to breadboard, and subsequently perfboard, is a vital process to the electronics maker – learn it, live it, love it!
New Product Guides
This week we also published a couple new product guides.
Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in both I2C and SPI!
This precision sensor from Bosch is the best low-cost sensing solution for measuring humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
