A brief overview of Allegro ACS712 current sensor. Part 2 – Interface the sensor with a PIC microcontroller
In the first part of this discussion, the features of ACS712 device were briefly discussed. Now we will use that theory to implement the ACS712 sensor to make a simple DC current meter. The analog output voltage from the sensor is measured through an ADC channel of the PIC16F1847 microcontroller. A voltage to current conversion
A discussion on the drive-current for the outputs of a PIC12C508A microcontroller
Each of the output lines of a ‘508A microcontroller can deliver a maximum of 25mA. What does this mean? It means any device connected to the line must take 25mA or less. If it takes more than 25mA a buffer transistor (also called an amplifying transistor) must be used and this will be discussed in a
