At the Toy Hospital, we held the first series of transistor circuit seminars from April to October of last year.After a short ...

Building a drone from scratch using the ESP32 microcontroller combines electronics, programming and engineering into a single project. Spencer Baum explains key foundational concepts, such as how ...

PWM Channels Microcontrollers (MCUs) are specialized microcontrollers equipped with Pulse Width Modulation (PWM) capabilities. These microcontrollers are designed to generate PWM signals, which are ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

LCD circuits often require a –10V voltage at 2 to 15 mA to bias a graphics-LCD-driver IC. You can usually accomplish this task with an external charge-pump IC, such as Maxim’s ICL7660, but that ...

[Hugatry] wanted to replace the adjustment pot on an LM2596 buck converter with a microprocessor-controlled voltage. The regulator IC uses a divider to generate a 1.25V reference from the output. The ...

Toshiba today announced availability of a new 32-bit microcontroller (MCU), the TMPM380. The TMPM380 MCU was specifically designed for the digital control of high-current circuits commonly found in ...

As engineers, there are many components and devices we use every day that we treat as black boxes. We only are concerned about the inputs and outputs of the black box, and this is acceptable provided ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

The proportional-control solenoids used in some industrial hydraulic systems are usually driven by microcontrollers or programmable logic controllers (PLCs). Such complex drivers typically require ...
