This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...
Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for the chip's power supply.
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 ...
