Arduino Controlled by Visual Basic Program

Arduino Vb Banner

Before this I’ve always used the Serial Monitor of the Arduino IDE to communicate with the Arduino. Actually what the Serial Monitor does is basically reading or sending data through the Serial interface. In my future project, I want to create an application in the computer that allows the user to click some buttons to control the Arduino. Currently, the …

I’ve been experimenting on ADCs alot recently and I suddenly thought of doing this small experiment. I’ll try to turn my Arduino into a voltmeter by using its’ analog input and the very powerful map() function. I’ll be using a HD44780 character LCD to display the voltage output and a 10k potentiometer to vary the input voltage going into the …

In this post, I’ll attempt to summarize everything I know about the ADC on a PIC16F877A and hopefully it will be informative to my dear readers. First and foremost, we must have a clear picture on what the built-in ADC is doing. Think of it like there’s …

Writing code for PIC Microcontrollers in C (Hi-Tech C Compiler)

Hitech Banner

I’ve always wanted to learn how to write PIC programs in C. You might think that’s odd but I was taught how to write in assembly language and not C unlike other universities or colleges. Most of the time it’s the other way around. Learning assembly code is a good thing actually because these C code will eventually be translated …
