Why isolate an RS-232 port An RS-232 cable is a long piece of wire that connects two pieces of equipment which are usually plugged into different sockets, sometimes in different buildings. The signal ground is shared, and with it every potential difference between the two supplies. In a lab that difference is millivolts. Next to […]

So here’s something super interesting and useful, a motor controller board powered by an Attiny13A to control a Brushed DC Motor. This Motor Driver uses PWM to control the gate of an N Channel IRFZ44N mosfet by the Tap of a single button. I’ve added Two Modes in the code that basically controls the

Introduction Several different approaches have been explored in developing a system to track eye movements. These approaches span from measuring reflections of infrared light to using advanced imaging techniques to monitor specific features within the eye. While a variety of reports exist on measuring infrared reflections off of the eye, the long term effects of

The abbreviation of AVR Microcontroller is “Advanced Virtual RISC” and MCU is the short term of the Microcontroller. A Microcontroller is a tiny computer on a single chip and it is also termed as a control device. Similar to a computer, the Microcontroller is made with a variety of peripherals like input & output units, memory, Timers,

Burning patterns into stuff with the focused suns rays…. about the level of eighth grade earth science before this subject was eliminated by our current Secretary of Education. But what if instead of just killing small arthropods with a death ray and then seeing spots before your eyes for ten minutes you could neatly carve
In this project we are going to tell you about how we can interface 7 segment display with 8051 microcontroller. Step 1: Software Used: As we are showing proteus simulation so FOR CODING AND SIMULATION YOU REQUIRED: 1 Keil uvision: Their are lots of product from keil. so you will be required c51 compiler. You can

In thid tutorial you will know everything ADC in avr microcontroller Step 1: What Is an ADC? An ADC, or Analog to Digital Converter, allows one to convert an analog voltage to a digital value that can be used by a microcontroller. There are many sources of analog signals that one might like to measure.

The assembly code given here was written to see what it would take to make an AT90S1200 generate 8 channels of proper PWM. In this case, by proper, I mean with the maximum high frequency content consistent with the needed duty cycle and give clock. Take a look at the scope shots below and notice
