R-B from embedded-lab send us his latest project. This time, he made a programmable ON-OFF timer for electrical appliances, based on the PIC 16F628. The visualization is done with a 16x2 green LCD display. With the 4 micro-switches, one can set the ON and OFF times. This means, that you can program when the device should be turned on, and for how long it should be kept on. The maximum time for both functions can be up to 99 hours 59 minutes. More info, schematics and code, can be found in his website. Thanks [R-B]!
