IOT modules with NodeMCU with ESP8266 WiFI part 1

IOT modules with NodeMCU with ESP8266 WiFI part 1

The ESP8266 WiFi chip The first thing you need to know is that the ESP8266 WiFi chip is much more than just a WiFi chip. It also includes its own microprocessor, 16 input/output pins, 64 KiB of instruction RAM and 96 KiB of data RAM. The ESP8266 wifi chip can me run...

Introducing the XLR8 FPGA-based Arduino Uno Clone

Introducing the XLR8 FPGA-based Arduino Uno Clone

XLR8(Accelerate) that has the same footprint as an Arduino Uno, but that runs like an Arduino Uno on steroids Regular Arduino Uno By default, the XLR8 behaves just like an Arduino, right down to its timing and 16 MHz clock. However, the XLR8's clock frequency can be...

Using a Washer To Steady Joints While Soldering

Using a Washer To Steady Joints While Soldering

If you have “helping hands,” clamping wire leads against a washer, as shown, stabilizes the whole setup dramatically by connecting the two arms with a rigid member, so you can bear down a bit more with the iron without pushing things out of alignment. But the hole in...

Pulling Larger Loads with Arduino Mosfet

Pulling Larger Loads with Arduino Mosfet

Arduino Mosfet layout If you are anything like me, this simply is not enough! No, you want to use this on your next Arduino project, but these LED's need lots of power. The Arduino only supplies 5V and even if it's a large 5V device the maximum current per I/O pin is...
