Microprocessors Garland

1. Presentation For some time now, I think the commercially available garlands, are too boring, too repetitive with their two or three alternations of colored bulbs. I wanted to create a truly personalized one without ruin me either. Two ideas immediately came: – a microprocessor to control all the lights, but at the cost of

Relay Controller

3-Channel IR Relay Controller with user programmable IR commands for PIC12F629

Description This project is a 3 channel infrared (IR) remote controlled relay driver.  It works with 12-bit SIRC IR signals as used by Sony remote controls. The controller also features the ability for the user to ‘program’ the commands it will respond to using  the IR remote control.   Each of the three relay channels can

Using Fixed Voltage Reference FVR for A D conversion in enhanced mid range PIC microcontrollers

Using Fixed Voltage Reference (FVR) for A/D conversion in enhanced mid-range PIC microcontrollers

The reference voltage plays a very important role in any A/D conversion. It determines both the range and the resolution (Volt/Count) of the A/D conversion. Besides, the accuracy of the conversion also depends upon how stable the reference voltage is. Usually in PIC microcontrollers, the reference voltage for A/D conversion can be selected as the
