The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. The MCP9808 comes with user-programmable registers that provide flexibility for temperature …

Here we look at 3 various Raspberry PI apps on android devices These seem to be a a better standard than the Arduino ones we looked at previously RPiRef on …

I have to say there are some fairly poor and mediocre Android app related to the Arduino. Generally there is very little content, way too many pop up ads and …

ElectroDroid is a simple and powerful collection of electronics tools and references. 

The TXB0108 8 Channel Bi-directional Logic Level Converter is useful for interfacing sensors or 3.3v logic components with 5v logic level microcontrollers. This unit will do the level shifting required …

In this example we will connect an LM35 temperature sensor to our Arduino The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius …

In this example we connect a photoresistor to an Arduino, the value read from the photoresistor corresponds to the amount of light present. The photoresistor is connected to analog pin …

In this example we will connect an RGB led to our Wemos MIni, lets look at RGB leds first RGB LEDs consist of one red, one green, and one blue …

This is a basic ‘barebones arduino’, this is an Atmega328 based design. In this example we are externally powering the Atmega from a 5v source, this removes the need for …

This is the second part of setting up an Arduino to program an Attiny microcontroller, in the previous parts we added support for the variety of microcontrollers. For reference purposes …
