I was recently asked to recommend a variety of arduino shields and boards for someone who wished to start learning but with a budget of only $30. Here are the boards and modules that I picked then I will explain …

VEML6040 color sensor senses red, green, blue, and white light and incorporates photodiodes, amplifiers, and analog / digital circuits into a single chip using CMOS process. With the color sensor applied, the brightness, and color temperature of backlight can be …

The VEML6075 senses UVA and UVB light and incorporates photodiode, amplifiers, and analog / digital circuits into a single chip using a CMOS process. When the UV sensor is applied, it is able to detect UVA and UVB intensity to …

Did you know that you can read the temperature from a DS3231 RTC – the DS3231 uses temperature compensation to calibrate the adjustable capacitors of its resonance circuit, in order to maintain time and date with accuracy The DS3231 is a …

We have just written an ebook and published it on the Amazon Kindle store, the topic of this ebook was looking at a variety of sensors with the Arduino IDE We have written this on the basis that you have …

I recently started looking through various shields I had no articles, code or tutorials for and came across a 2.8 Inch TFT LCD Shield Touch Display Screen Module For Arduino Its a cracking display, here are some pictures of it …

In this example we connect a PAJ7620 gesture sensor to an Arduino Uno The PAJ7620 integrates gesture recognition function with general I2C interface into a single chip forming an image analytic sensor system. It can recognize 9 human hand gesticulations such …

Another sensor reaches the desk, this time it is a Si1145 sensor, we will connect it to an Arduino and test it out First the sensor The Si1145/46/47 is a low-power, reflectance-based, infrared proximity, ultraviolet (UV) index, and ambient light …

In this article we look at the TMP102 digital sensor and we will connect it up to an Arduino – lets start with some technical info about this sensor The TMP102 device is a digital temperature sensor ideal for NTC/PTC …

In this article we look at the MPU-9255 and an Arduino, lets look at some information about the sensor MPU-9255 is a multi-chip module (MCM) consisting of two dies integrated into a single QFN package. One die houses the 3-Axis gyroscope …

This Rich Shield for the Arduino has many useful components onboard such as LED’s, buttons and a buzzer. It is easy and great for learning arduino development and programming This is the shield with a little remote control, we will …

The HY-SRF05 is an ultrasonic emitter/receiver used to measure distance with a precision of ~0.3cm. It sends out a 40 KHz square wave signal that reflects on objects in front of the sensor. This signal is then read back by …
