An Arduino is a development platform used by many development kits that operate using Atmel-based microcontrollers. Arduino doesn’t refer to a particular microcontroller, but rather a platform for microcontrollers. For example:The Arduino Uno used in this tutorial is a kit that has an AtmelATmega...
Now that we knowhow the MQ-3 alcohol sensor works, we can connect all necessary wires to an Arduino Uno and see how it functions. We'll start with the analog component and then go on to the digital part, which is pretty simple. To work with the Sensor, we must first power it. We...
Step 3: Set the Arduino Uno Into ISP Mode Since what we want is to be able to program the ATtiny85 from the Arduino IDE which requires to burn the bootloader to the ATtiny85 we will need to "prep" the Arduino fist by uploading the ISP sketch to it. In the Arduino IDE select File-...
How fast is Arduino shiftIn()? The function uses digitalRead() so it should be similar to the speed of digitalWrite() - in that link the pulse period (for an Arduino Uno) is 7us. Since 8 pulses are needed, shiftIn() should take about 56us plus a bit more for bit manipulation and...
How to Connect a Serial LCD to an Arduino UNO: In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO. There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many sho
One common error that Arduino users may encounter is the ‘does not name a type’ error. Let’s take a look at what this error means and how it can be fixed. What Does ‘Does Not Name a Type’ Mean? The ‘does not name a type’ error is an indication from the Arduino IDE that...
Maze Solving Robot with Arduino UNO Building a maze-solving robot is an intresting way to get into the world of robotics and autonomous systems. Imagine creating a small device that can intelligently navigate through complex mazes, making decisions at every turn. This step-by-step guide will sho...
The sensor senses the intensity of reflected light to give an output. The sensor’s output is fed to the microcontroller, which gives commands to the motor driver to drive the motor accordingly. In our project, the Arduino Uno is programmed to make the robot move forward, turn right or ...
In this article, we’ll look at a basic use case involving data collection from a temperature sensor connected to an Arduino Uno, then sent to InfluxDB via the native UDP plugin. Why UDP? Since most of the processors present in Internet-enabled devices are designed to be energy-efficient ...
