Actuators are the moving part of a device that controls the mechanism of a system. A simple example of an actuator is the opening of a valve. With this simple example of a solenoidal valve, we can understand that an actuator (or, in other words, a part that performs a movement in a specific direction) needs […]
SparkFun Electronics Thing Plus – STM32 offers power and precision with a 32-bit ARM® Cortex®-M4 RISC core. The Thing Plus provides a DFU bootloader for uploading code and incorporates an extensive range of enhanced I/Os and peripherals. The STM32 Thing Plus utilizes the handy Qwiic Connect System, which means no soldering or shields are required to connect it. The STM32

We have already seen several modules coming to the market by Seeed Studio that was based on the SSD202 SoC, which integrated Arm Cortex-A7 processor core running at a clock frequency of up to 1.2GHz. Since this SoC is widely used in smart display applications, Seeed Studio has introduced yet another ultra-small system on module (SoM), IDO-SOM2D02-V1-2GW SoM, designed with 128MB DDR3 RAM

When it comes to securing your system, there are always some loopholes that you’d want to know. In context to information technology, we have cybersecurity masters working on it to help organizations and corporates keep the information intact and keep the system safe from any external attacks. One such protective measure is trying the red

This is a precision, low power, and easy-to-use oscillator that provides multiphase outputs. The output frequency of the project is set to 250Khz, with 40% spread spectrum. The oscillator frequency can be set by resistor R1, and the spread spectrum can be changed using R3. The master oscillator is controlled by the RSET resistor R1 and has a
In 1971, Signetics—later Philips—introduced the NE555 timer, and manufacturers are still producing more than 1 billion of them a year. By adding a few components to the NE555, you can build a simple voltage-to-frequency converter for less than 50 cents. The circuit contains a Miller integrator based on a TL071 along with an NE555 timer
