This project is built for fun loving users to create a 24 LED bar-graph for light effects that can be driven using Arduino or another microcontroller. The project consists of 74HC595 x 3 chips, and 24 LEDs of Red, Green, Blue, and Yellow colors. The project helps the user to...

The project presented here is a versatile high voltage Half-Bridge with current feedback. The board is built using L6390 IC from ST Semiconductor. It is suitable for DC-DC converters, EHT drivers, induction heater drivers, battery chargers, LED drivers, DC motor speed controller and...

  ThermoDuino is a mini Arduino compatible board that consists of LM35 temperature sensor, ATMEGA328 chip, and 0.96" OLED display. The board has been designed to measure temperature. We have used the LM35 SO8 SMD sensor which is connected to A0 analog pin of the chip, and the...

The project presented here is a Digital Pressure Gauge using an OLED display. The measuring range of this unit is 0 to 10kPa (0 to 1.75 psi). Additional this compact open-source hardware is Arduino compatible. This board can be used for measuring low pressure up to 1.75psi with great...

This is an easy to build small size and low-cost room thermometer. The project consists of LM35 analog temperature sensor, 16x2 LCD, and an Atmega328 chip. This compact board is Arduino compatible and provided with an onboard connector for Boot-Loader burning and Arduino IDE...

This is a Smart LED light stick that contains 20 x WS2812B single wire addressable full colors RGB LEDs and Atmega328 microcontroller. These full colors chainable intelligent RGB LEDs work with a single wire addressable protocol thus they require a micro-controller to generate the...

This is a 3-channel, PWM based current-adjustable LED driver designed for RGB LED control. The circuit has been designed to control high current RGB LEDs or RGB LEDs strip. Colors of the three RGB LEDs can be set using 3 potentiometers, different colors are possible by adjusting these...

This project provides an economical and precise solution for DC current sensing and display on an OLED display. This board uses the ACS715T-20A hall effect-based linear current sensor chip, 0.96 Inch I2C OLED Display and Atmega328 microcontroller chip. It is an Arduino compatible...
