This low-side voltage-to-current (V-I) converter delivers a well-regulated current to a load. The circuit accepts an input voltage from 0V to 3V and converts it to a current from 0A to 6A (combined). The current is accurately regulated by feeding back the voltage drop across a...

The project presented here is a micropower no-opto isolated flyback converter featuring the LT8304 chip from Analog Devices. This circuit outputs 12V and maintains tight regulation with a load current from 10mA up to 1A and over an input voltage from 18V to 28V. The project needs less...

This project is an inclinometer based on the ADXL203/ADXL103 accelerometer chip and the Arduino microcontroller ATMEGA328. The device measures tilt and displays it on a 17-segment bar graph display. The ADXL203 provides an analog value, which is read by the ATMEGA328's ADC A0 and...

If you have a new ATmega328P you’ll need to burn the bootloader, to be able to upload a sketch with Arduino IDE. You can do this using this simple-to-use bootloader burning tool. The board consists of 32-pin TQPF adapter and Arduino Nano. Place the new ATMEGA328 TQFP chip into...

The project presented here is a compact, high-efficiency, low-cost, and low-EMI step-up DC/DC module designed to replace LDO regulators. This small module not only saves on solution size and cost but also eliminates the need for a heatsink, occupying the same space as a TO-220 package...

This project enables the measurement of fuel levels in a tank using a resistive float sensor. The fuel level is measured and displayed on an OLED display. The project is compatible with Arduino and features an ATMEGA328 microcontroller. The resistive sensor, connected to a divider...

This Bluetooth Smart LED Dimmer, 4 Channel ON/OFF Switch is a versatile device that enables users to control various devices, including lights, fans, and DC motors, using a Bluetooth app on an Android device. The device features a 4-channel dimmer that can handle inductive or...

This Bluetooth Relay Switch enables users to control lights, fans, or other devices using a Bluetooth app on an Android device. The device can be controlled using a simple app. The project consists of an Arduino-compatible microcontroller (ATMEGA328), a 5V relay, a relay driver BJT,...
