The Si4702/03 integrates the complete tuner function from antenna input to stereo audio output for FM broadcast radio reception The Si4703-C incorporates a digital processor for the European Radio Data System (RDS) and the US Radio Broadcast Data System (RBDS) …

The TCS3200 and TCS3210 programmable color light-to-frequency converters that combine configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity …

A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications. In its simplest form, the sensor operates …

Another sensor and this one goes by the title of a Ky-032 Infrared Obstacle Avoidance Sensor Module Basically its an IR emitter and receiver, the receiver detects when an obstacle has been placed in the beam of the IR emitter …

This is another example using a sensor from the 37 sensor kit, this time we use the one called the KY-033 Hunt sensor module. A more correct name would be a IR Line tracking sensor The sensor has IR light …

Port registers allow for lower-level and faster manipulation of the i/o pins of the microcontroller on an Arduino board. The chips used on the Arduino UNO board have three ports: B (digital pin 8 to 13) C (analog input pins) …

The Relay Shield features four high quality relays and provides NO/NC interfaces, four dynamic LED indicators to show the on/off state of each relay, and the standardized shield form factor to provide a smooth connection to Arduino compatible boards. Product …

In this example we will connect an RGB led to a Digispark, a quick recap of the basic Digispark we ware using in this example XGHF-GY Digispark Kickstarter Miniature Development Board TINY85 – Blue – $4.65 The Digispark is an …

In this example I decided to take a look at one of the Digispark clone boards that are available. These boards are based around the ATtiny85 which have the micronucleus bootloader installed, this means you can then use the Arduino …

In this example we will add bluetooth support to our Arduino, there are several low cost modules labelled either Hc-05 or HC-06. Here is a picture of one of them In this example we will connect one of these modules …

The BME280 is a humidity sensor features an extremely fast response time which supports performance requirements for emerging applications such as context awareness, and high accuracy over a wide temperature range. The pressure sensor is an absolute barometric pressure sensor with …

MCP4725 is a single channel, 12-bit, voltage output Digital-to-Analog Converter with integrated EEPROM and an I2C Compatible Serial Interface. Features 12-Bit Resolution On-Board Non-Volatile Memory (EEPROM) ±0.2 LSB DNL (typ) External A0 Address Pin Normal or Power-Down Mode Fast Settling …
