LEAP#344 MicroPython on the ESP8266
I first heard about MicroPython from the kickstarter campaign to open source the software.
Although it makes more sense to use it with a more capable board, I’m starting with a test on a 512kb ESP-01 module.
Nice … python on a micro, running Star Wars ascimation!

LEAP#343 ESP8266 DHT11 Sensor Reading
The DHT11 sensor is a very cheap and common sensor that provides readings of relative humidity (20-80% ±5%) and temperature (0-50°C ±2°C).
I’ve used this before with an Arduino, this time I’m testing with the most basic ESP8266 board - an ESP-01, which exposes one free GPIO. For coding I’m using ESP8266 core with the Arduino IDE, and the Adafruit sensor library to interface with the DHT11.

LEAP#342 ESP8266 Morse Blinky
A quick test of the ESP8266 core for Arduino, which brings support for ESP8266 chip to the Arduino IDE.
That means being able to write C++ sketches for the ESP8266 as easy as developing for an Arduino.
Here I’m using the most basic ESP8266 board (an ESP-01) with a sketch that blinks Morse code on the built-in LED.

LEAP#341 USB Power Supply
I’ve taken apart and had enough “wall wart” power supplies blow up on me .. so perhaps it is about time to put one together instead!
Cheap kits are available, although it pays to carefully map out the circuit and understand how it functions, as schematics don’t always match PCB/silkscreen, and components may also vary! The kit I’ve built here works just fine..
