Before learning about low power consumption in PIC microcontrollers, let’s briefly go over some basic knowledge and concepts related to low power consumption. Power (Watts) = U (Volts) * I (Amperes) Energy (Joules) = U (Volts) * I (Amperes) * t (Seconds) Charge (Coulombs) = I (Amperes) * t (Seconds) Power consumption can be divided … Read more
Q A & Question:Examples of Arduino Sleep Mode I decided to write my own examples to demonstrate how to put the Arduino into sleep mode. You might wonder, what’s the need for this? The answer is: if your project is powered by batteries, this setting can be very useful. Putting the Arduino into sleep mode … Read more
