This low cost low voltage 3W class-D stereo amplifier is based on PAM8403 IC, The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filter-less architecture allows the device to drive the speaker directly,...

Unipolar stepper motor driver can drive unipolar motor up to 3.5A and supply range 10 To 50V DC. The board has been designed using STK672-442AEN IC.  The STK672-442AN is a hybrid IC for use as a unipolar, 2-phase stepper motor driver with PWM current control and...

Introduction Hi guys, today we will be focusing on displaying mini graphics and texts on an 8x8 LED matrix using the MAX7219 (or MAX7221) LED driver and the Arduino Uno.   The 8x8 LED matrix displays are usually used for the display of symbols, simple graphics and...

This 3 in 1  shield for Arduino Nano helps to develop various temperature measuring applications. Arduino Nano shield consists of 3 different types of temperature sensors. MLX90614 non-contact temperature sensor 10K NTC Analogue Temperature Sensor Programmable Resolution...

Introduction Hi guys, continuing on our recent path of building really cool stuffs based on the Nokia 5110 LCD display, today we will be building a DIY Lux (or light) meter using the highly sensitive BH1750 light sensor. Illuminance (measured in LUX) is the total luminous flux...

This project features an easy-to-use Digital to Analog converter (DAC) shield for Arduino Nano. The project is built using MCP4725 12Bit DAC IC over I2C communication. The shield directly seats on Arduino Nano and also can be used as stand-alone DAC converter that can be connected to...

Introduction Hi guys, in one of our previous tutorials, we made a real time clock, using the DS3231 RTC Module and the 1602 LCD display module. For this tutorial, we will be building something similar using the DS1302 RTC module and the Nokia 5110 display module. Unlike the 1602 LCD...

This is a 60 V 3A step down DC-DC converter. Sample applications are: 12 V, 24 V and 48 V Industrial, Automotive and Communications Power Systems. The TPS54360 is a 60 V, 3 A, step down regulator with an integrated high side MOSFET. The device survives load dump pulses up to 65V per...
