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…

The Attiny85 is a nice little 8 pin chip which is ideal for simple projects, they are low cost and if you have an Arduino you can actually burn the…
