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 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

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

In the last tutorial we learn about the multiplexing technique used with seven segment displays. We learnt how it saves i/o line by using persistence of vision. Only one digit is lit at a time, but to a human eye it is too fast to catch, so we see all four digit lit the same

In this article you will learn, Digital Thermometer using pic microcontroller and MCP9700: In this tutorial, we are making a Digital Thermometer using PIC microcontroller and LM35 Temperature Sensor. In this project, we will sense the temperature using LM35 and display it on 16×2 LCD. LM35 Temperature Sensor is accurate and cheaper and doesn’t require any
