How to wire a switch to a microcontroller with pullup resistors

October 3, 2016 By Scott Thornton Leave a Comment

If you want a button or switch as an input on a microcontroller (MCU), you can use a “pullup resistor” so that the input is seen as a logical high when the (normally open) switch or button is closed. A pullup resistor is connected to Vcc, or logical high for your input, and therefore “pulls […]

A beginner’s guide to microcontrollers

December 2, 2015 By Aimee Kalnoskas 7 Comments

by Jon Wilder Time after time I see beginners try to get started in embedded electronics, only to be overwhelmed and not know where to start. Some even make the mistake of trying to write their own code without first gaining a thorough understanding of the microcontroller/microprocessor they’re working with, the programming language they’re working […]

timer 0 and PIC16F628A

June 22, 2015 By Aimee Kalnoskas Leave a Comment

by Jon Wilder The on-chip timer on PICs is confusing to some. But, not to worry…it’s probably one of the simplest on-chip peripherals to use on a PIC. In this article, we’ll use the PIC16F628A as our example of why that’s true. Timer 0 (TMR0) is one of three timers available on the 16F628A that is running […]

How To Monitor I2C Communications Through RS232

October 10, 2014 By Aimee Kalnoskas 1 Comment

by Electro-Tech-Online member languer In the past when requiring to monitor I2C communications between two devices I would use a logic analyzer. Such monitoring was useful to determine if the I2C communications between devices was properly configured. Even though this is quite useful and efficient, it does require a logic analyzer, with an I2C protocol […]
