I got to thinking that an interest in hi-fi can be a bit geek ( in a good way ) so I thought one of my latest geek projects might be of interest to some of you. You could build the project ‘as is’ without learning embedded C programming or you could use the project […]
PIC 16F88 Digital Thermometer Light Meter and resistance ohm meter. My original idea for this project was simply to try and interface the WINTEK WD-C2401P lcd panel to the pic (see my previous post). I figured it would be fun to add a couple of ADC readings to display something useful on the lcd. Theory

Hello, everyone !!! Today I’m going to show you how to make a thermometer with Arduino and LM35 termperature sensor, builded on a breadboard and conected together with jumpers (bunch of cables :D). Step 1: Gathering The Parts This is the list the parts needed to make the thermometer. If you dont have a 10k
This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor

Here we have a clock. It’s not “another clock”. It has digital and binary output. It also has a thermometer and a hygrometer. It’s not “another thermo-hygrometer”. It display’s absolutely humidity (gr/m3) also. Schematic MCU I build it around Microchip PIC16F917, with internal Oscillator at 4MHz. I also build a serial port programmer, so

The heart of the device is TI’s MSP430RF5728 microcontroller (μC) with FRAM type of memory instead of conventional Flash. This simplifies and speeds up writing to memory and from the user’s viewpoint there is no difference between RAM and FRAM access. No preliminary block erase is needed by writing a single byte into FRAM. However,
Updated on 17/01/2016 (a and b segments were swapped on drawing) Counter based on PIC16F628A . Included C code and circuit diagram. Displays -55 to 125 centigrade. The temperature is read every 15 seconds, can be changed in the code. The math is using integers to calculate the degrees and the tenths of degrees are

The seven segment display is one of the most popular numeric displays used in many microcontroller applications because it’s cheap, robust and reliable. The seven segments actually consists of 8 LED (Light Emitting Diode) and it’s come with various sizes suitable for various numeric display application such as digital clock, counter, thermometer, humidity, etc. On

With summer arriving, and the fear of dried out chicken looming, we wanted a more high tech way to track the temperature of items we are grilling outside. There are wireless probe thermometers, but they require carrying around a separate readout. We wanted a way to read the termperature from our smartphone, so we took
USB Indoor/Outdoor Thermometer (or, ‘My first USB device’) This is a simple design that demonstrates the USB peripheral on the PIC 18Fs. There are a bunch of examples for the 18F4550 40 pin chips online, this design demonstrates the smaller 18F2550 28 pin version. The PCB uses surface mount parts, but all components are available
