Introduction Tired of spending hours and hours in wire soldering? Do your circuits look ugly and you are looking for a way to produce professional-like PCBs? Then you had better try photoetching. And the first step to do that is to have the right equipment that is an Automated Exposure Box. Moreover if you like

This instructable describes how to integrate hobby servos (the kind used in RC planes, cars, etc.) into your microcontroller projects. Step 1: How Servos are Different from Regular Motors In a regular DC motor, the amount of torque the motor exerts on the shaft is proportional to the amount of current flowing through the motor.

The intel 8051 series 8bit microcontroller, originally introduced in 1980, remains popular and has had perhaps the longest product life of all such devices. It has become the industry standard for real-time and Boolean control applications. While some (who should know better) have said that the 8051 is dead, it continues to be a viable

Introduction When working with microcontrollers that require a factory calibrated osccal value stored in memory, its very normal that once in a while this setting could be lost during an upload of a new program or when accidentally erasing the device. Im no exception and erased many times this value by mistake in several devices.
