Tutorial: Building cool projects with MCUs (Part 3) As we proceed onto the third portion of this microcontroller tutorial, let’s first revisit what we have accomplished thus far. In Part 1, we defined what a microcontroller actually was. I wanted to get everybody on-board (no pun intended) for this, so I started from scratch. Feel free to […]

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
This post provides the external interrupt code for PIC12F675 microcontroller (e-g when you need to control servo motor which has position encoder, with your PIC microcontroller). As we know, PIC12F675 microcontroller has one GP2/INT pin, which can be used to service external interrupts. This code is written in C language using MPLAB with HI-TECH C compiler. You

Description Here’s another daft yet interesting PIC12F675 idea I came up with. When I wanted to show someone how logic gates worked I could only find a NAND gate which wasn’t very handy for demonstrating AND’s OR’s, NOR’s and ExOR’s. I also wanted to have a play with the A/D converter on the 12F675 so

Objective To establish serial communication between two PIC16F877A microcontrollers Description In this experiment, 8-bit digital input is applied at Port-B to one of the PIC16F877A microcontroller which acts as a master in serial communication. The input value is transmitted by the master serially via Serial Peripheral Interface (SPI) to the second PIC16F877A microcontroller, which acts
