This is an under-speed sensor module that provides an audible warning and signals output when the speed of a machine is below the set point. The module can be used in applications such as Engines, Machines, Sports machines, Fitness Equipment, Speed of the machine or engine can be...

The project presented here is a low-cost solution to control high power brushed DC motor speed and direction. Traditional DC motor controllers are based on solid-state circuitry known as H-Bridge. Here we have made an H-bridge configuration using high current 2 x relays which can...

The project presented here is a low-cost easy to use DC brushed motor direction controller with fast-brake, the project was built using two 12V Relays, 2 x BJT transistors, and 2 x tactile switches. The two LEDs are provided to display the motor direction, 2 tactile switch controls...

This is a multiple output power converter module that provides +/-10V (Dual 10V), 5V DC, and 3.3V DC from a 9V PP3 battery. This is a very useful project that has been designed for low-load current applications. Dual +/-10V output from a 9V battery is a key feature of the project. The...

This BLDC motor driver board is equipped with a smart IFX007T half-bridge. The BLDC motor control project is capable to drive one BLDC motor. Alternatively, it can be used to drive one or two bi-directional DC motors (H-Bridge configuration, cascaded to support the second motor) or up...

This DC Motor controller provides direction and speed control of brushed DC Motor using Rotary Encoder. This is Arduino compatible hardware that consists of LMD18201 DC motor driver chip, Atmega328 microcontroller, Rotary Encoder, L317 regulator, and other components.  Hardware...

The circuit shown here is a frequency-to-voltage converter that can be used in many applications. This is a signal conditioner for Variable Reluctance Magnetic Pickup Sensor used in engines or machines to detect the speed by sensing gears' teeth. The input signal level is 20mV to 28V....

The circuit shown here is a complete microphone signal conditioning system based on a single SSM2166 integrated circuit. Designed primarily for voiceband applications, this integrated circuit provides amplification, RMS detection, limiting, variable compression, and downward...
