The LM317 Regulator Mini Lighthouse LED Circuit

Do you know why this project named as “Mini Lighthouse LED circuit”? It’s because the LED circuit has a shape like a lighthouse and that’s the reason it got the name here! Basically, this is a simple “lighthouse” that when it’s powered up, it will rotate the beam around the 12 LEDs. This Mini Lighthouse LED Circuit is a very useful tool, especially for a model railway. For your information, this Lighthouse has several interesting features. The first feature is a full size ICSP connector, while the second is a socketed DIP version of the PIC12F683. Those 12LEDs is the maximum numbers of you can charlieplex from four tri-state pins. The PIC12F683 is an eight pin device that has five GPIO plus the MCLR pin, where it can be used as an input. You can keep one GPIO spare, GPIO four where it also happens to be an analog port that allow you to add a light sensor that turns the lighthouse on when it gets dark. Furthermore, this version has an LM317 regulator on the back so it can… Continue reading

DC Boarduino – A Clone Will Make It Good

Did you ever have this experience before? You’ve been struggled to use a solderness breadboard with an Arduino, and you know how annoying it can be. Now, you can dump all of the frustrating into the dumpsite with this new DC Boarduino. This DC Boarduino is a clone that can works with the latest Arduino software. The assembly is so easy to operate and well documented. DC Boarduino features: Well designed to plug into a breadboard Its only sized 3″ x 0.8″ (75mm x 20mm) All pins were brought out – Digital 0 thru 13, Analog 0 thru 5, ARef, 5V, Ground, Vin and Reset A preprogrammed “no-wait” Arduino bootloader 2 LEDs, green power and red “pin 13” Low cost that everyone can affordable All through-hole parts Reset button ATmega168, running at 16.00 MHz 6-pin standard ICSP header Standard 2.1mm DC jack with 5V regulator 6-pin header at the end for a USB-TTL cable Auto-reset capability (with the used of USB-TTL cable) The only matter is this DC Boarduino doesn’t include a USB chip, so you will want an FTDI… Continue reading
