Analog-to-digital converters (ADCs) are used in a wide range of electronic devices. However, most of the low-cost microcontrollers do not include an ADC peripheral. This design idea provides a way to ...

A brushless dc motor needs several voltage levels to control its speed: 0V to stop the motor, 5V to run it at maximum speed, and some voltages between these extremes to run it slower. When you use ...

Drawing and analysing flowchart diagrams involves elements like count, compare, macro, do macro, end, increments, decrements, and expressions. Microcontrollers (PICs) are used in control systems, ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...

These steps are thenrepeated until the reading is correct at the mid and max values. Thisis usually necessary because the gain and offset interact, that is,adjusting ...

Here’s an interesting article about reading data from shift registers using less than three pins. 74HC165 shift registers are a popular choice for adding inputs to a microcontroller. They have a ...

GUEST OPINION: Choosing a suitable microcontroller is a crucial stage of any electronic system creation. MCU works as the brain of an application, managing the communication between components and ...
