TINY CHEAP ARM BOARDS GET WIFI

Over the last few years, we’ve seen the value of putting tiny WIFi-enabled microcontrollers on a module that costs a dollar or two. Those smart light bulbs in your house probably have an ESP8266 in them, and you can build a WiFi-enabled anything with one of these chips for next to no money. Now there’s a new module that takes the design philosophy of, ‘a reasonably powerful microcontroller, on a module, tha ...

RemoteDebug for ESP Platforms

Debugging tools are critical to quick and effective development. Without being able to peek under the hood at what’s really going on, it can be difficult to understand and solve problems. Those who live on the Arduino platform are probably well acquainted with using the serial port to debug, but it’s far from the only way. [JoaoLopesF] has coded the RemoteDebug tool for ESP platforms, and the results are im ...

Arduino omni-wheel robot and pen plotter

Instructables member “Lingib” has created a awesome Arduino powered Omni Wheel CNC pen plotter, powered by an Arduino Uno and Bluetooth module allowing the system to receive commands via a linked smartphone or tablet. If you’re not familiar with omni-wheels the unique wheels only provide traction in the direction of rotation. Any oblique force causes the wheel to move sideways. Check out the video below to ...

INEFFICIENT NEOPIXEL CONTROL SOLVED WITH HARDWARE HACKERY

Everyone loves NeoPixels. Individually addressable RGB LEDs at a low price. Just attach an Arduino, load the demo code, and enjoy your blinking lights. But it turns out that demo code isn’t very efficient. [Ben Heck] practically did a spit take when he discovered that the ESP32 sample code for NeoPixels used a uint32 to store each bit of data. This meant 96 bytes of RAM were required for each LED. With 4k o ...

DRIVING A CONTROLLERLESS LCD WITH THE HUMBLE ARDUINO UNO

These days, you could be forgiven for thinking driving an LCD from a microcontroller is easy. Cheap displays have proliferated, ready to go on breakout boards with controllers already baked in. Load up the right libraries and you’re up and running in a matter of minutes. However, turn your attention to trying to drive a random LCD you’ve yanked out of a piece of old equipment, and suddenly things get harder ...
