The PCA9685 is an I²C-bus controlled 16-channel LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM…
The LSM303 3D Accelerometers/Magnetometer Models are a system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. These best-in-class eCompass devices enable superior PDR or unique use…
BH1750FVI is an digital Ambient Light Sensor IC for I2C bus interface. This IC is the most suitable to obtain the ambient light data for adjusting LCD and Keypad backlight…
The PCF8591 is an 8-bit CMOS data acquisition devices. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 has three address pins…
The MAG3110 is a digital 3-axis magnetometer. The device can be used in conjunction with a 3-axis accelerometer to realize an orientation independent electronic compass that can provide accurate heading information.…
In this example we will connect and LDR up to our Arduino and display the reading on a bargraph display. A typical bargraph display looks like the one below, mine…
In this project we will display temperature from a DS18B20 on an OLED display. Here is a picture of my project, you can see the temperature displayed on the OLED…
Just recently I spotted various I2C OLED displays on sale at reasonable prices and fancied trying to connect these up one of my Espruino. Being relatively small size, requiring only…
In this example we use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor. The DHT22 is better…
A light-dependent resistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied…
