First Servomotor Control Program

In our first program , we will simply sweep the servomotor from CCW to CW and then sweep back. The program will be kept simple as to demonstrate the priniciples of controlling a servo with a the PIC Basic language. The schematic can be seen in figure 2 (below). The variable pw controls the pulsewidth,

Infra red remote control tester for Philips RC5 protocol

Philips invented the RC5 protocol for controlling electronic equipment such as CD players, VCR’s and audio amplifiers way back in the 1980’s. The RC5 standard has been adopted and used with great success ever since, which means it is probably the most common IR remote control format in your home today. We have recently been
