This angle sensor module features an ADA4571 chip, an anisotropic magneto resistive (AMR) sensor with integrated signal conditioning amplifiers and ADC drivers. The circuit produces two analog outputs that indicate the angular position of the surrounding magnetic field. The ADA4571...

The project described here is a 10-minute timer using an Arduino microcontroller, capable of driving AC loads up to 30A. The timer's progress is visually represented by 10 LEDs, which light up sequentially, each for 1 minute, totaling 10 minutes. The project is powered by a single...

The project presented here is an isolated flyback converter featuring the LT3748 chip from Analog Devices. The circuit is designed for a +/-340V DC (2 x 340V) output from a 7V to 15VDC input. The output current is up to 2 x 8mA. The board senses the isolated output voltage directly...

This project provides High Voltage and High Current output swing. The board is built using OPA454 OPAMP and 2 x high current NPN/PNP BJT Transistors. Output transistors Q1 and Q2 provide positive and negative output currents to the load. The project works with an input power supply up...

  The project presented here is a Voltage Controlled Amplifier (VCA). A VCA board helps users control the audio level from a remote potentiometer. This board requires a balanced audio signal. Gain control voltage can be adjusted through potentiometer R13. The project works...

This Fuel level Monitor allows users to measure the fuel level using a resistive float sensor in the fuel tank. The project measures the fuel level and displays it on a 15-segment bar-graph display.  The project is Arduino-compatible and consists of ATMEGA328 controller. The...

This simple Arduino compatible project reads an RC PWM signal (1000μs to 2000μs) and provides 0 to 500Hz pulse output to drive a stepper motor. Step and Direction outputs are open collector types 5V signals. Both signals can directly drive LEDs of optocoupler of stepper drivers. The...

This is a Half-bridge module based on the LM5104 chip, which is a high-voltage gate driver. This High-Voltage Gate Driver is designed to drive both the high-side and the low-side N-channel MOSFETs in a synchronous buck configuration. The floating high-side driver can work with supply...
