- Part 1. Schematic Part 2. Software Output The use of this device is very simple. Turn the power on, and you will see all zeros on display for few seconds. Wait till the display goes off. Now place your forefinger tip on the sensor assembly, and ...Mar 28, 2011
- Keypads are a very commonly used input device in microcontroller-based systems. In a keypad, multiple switches are arranged in rows and columns so that they could be interfaced to a microcontroller with a minimum number of I/O pins. For example, a ...Mar 25, 2011
- .. connected to the microcontroller with individual pull-up resistors on each input. In this project I used RB4 and RB5 on the PIC to connect the encoder; this has 2 advantages, firstly you can use the PORTB internal weak pull-up (which means you ...Mar 25, 2011
- Rajendra BhattPart 1. Schematic Software The firmware does all the control and computation operation. In order to save the power, the sensor module is not activated continuously. Instead, it is turned on for 15 sec only once the start button is pressed. The ...Mar 14, 2011
- .. the code. You simply need to compile the PICDEM FS USB projects which are included with the stack examples. Building the PIC DEM FS USB board The circuit schematics for the original board are available on-line from Microchip, they publish ...Feb 26, 2011
- Introduction Heart rate measurement indicates the soundness of the human cardiovascular system. This project demonstrates a technique to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the ...Feb 11, 2011
