Microchip’s 8-bit tiny and small 8 pin programmable EEPROM chip IC PIC12F629 has the capability to perform Pulse Wave Modulation with lighting and dimming and power saving of energy by at least 50% by PWM switching in Dual switching or Quad switching . The movie and video below shows lighting and dimming of the LED’s similarly to a candle or viewed from Fibre optic cables as dimming as data passes through. This is utilized mainly in conserving energy and can reduce household consumption up to 50% of lighting energy . The PIC 12F629 chip IC is reprogrammable and can be programmed again with different frequencies or a program update and plugged in and utilized again or programmed on board the PCB . It’s widely utilized now in the energy market and available from Prof Dr Chan Junt Hoong FIET FIEEE BEng CEng . Published and Written by Prof Dr Chan Junt Hoong FIET FIEEE BEng CEng .
