Program LinkitOne to Control the Coffee cup using Bluetooth android app.Attach the LM35 temperature sensor to A0 pin, Transistor base switch and Bluetooth antenna to LinkitOne.Thus LM35 reads the temperature and send it to android app through Bluetooth....
Connect the two pins from the Sensor to the two pins on the Amplifier circuit via hook up wires. Connect the Vcc from the Amplifier to the 3.3V pin on the Arduino and the Gnd pin to the Gnd pin on the Arduino. Now connect the Analog Data Pin to the...
Make the following wiring connections: Connect the VCC pin to +5-volt pin of the Arduino board.Connect the GND pin to the GND pin of the Arduino board.Connect the OUT pin to the A0 pin of the Arduino board.
1. Connect buzzer to D7 and Ground2. Connect button to D6 and Ground3. Connect potentiometer to A0, 3.3v and Ground4. Connect battery to VIN and Ground5. Upload the code6. Print the case front7. Fit inside an Altoids can and you are ready
Not all ESP 8266's GPIOs are born equal, something I have now and then been banging my head at (and burned some ESPs). Some are hard wired for some use, like SPI clock and data, some wired to functionality like flashing and booting. For now Wemos D1...
Solder up them Address-Lines (And Clock)The core-concept behind sdramThing is that of loading (half of) the memory-locations with commands that will be (eventually) directly fed-back to the SDRAM itself. Taking into account the characteristics of SDRAM,...

Although optional, it is highly recommended to test the board so far with the free run test. Connecting the databus to the ground, the CPU will read in 0x0000.0000 as an instruction and will execute a kind of NOP (in fact, it will execute ORI.b #0,D0)....
Download the Arduino IDE from here if you don't have it on your computer. Then download and open the given code:int i=0; //Integer to store the locomotive's speed at a scale from 0 to 255. int switchLimit = 80;// Integer to store the speed limit...
If your room is dark and it's on all the time, add the second blue resistor to make the photocell less sensitive to light! Move the 10k resistor from B1 to B4, leave B7 in placePlace the other 10k resistor from A1 to A4
*** FIRST DOWNLOAD AND INSTALL THE PASSWORD AND KEYPAD LIBRARIES *** JUST EXTRACT THEM IN ARDUINO LIBRARIES FOLDER Install the above mentioned two libraries. You can download them directly from the library manager or you can download the zip file and...
This instruction is for building the transformer. It describes materials and fabrication guidance but assumes the reader has experience assembling magnetics. Additional information can be found in the magnetics zip file and the 'inductors'...
