Build a digital spirit level using a SCA610 accelerometer using PIC16F684

A bubble or spirit level meter is a handy tool to find whether a surface is horizontal or vertical. It is often carried by civil engineers, mechanical engineers, surveyors, carpenters, and many other professionals whose work involve precise alignments of horizontal and vertical planes. Original spirit levels had two banana-shaped curved glass vials at each viewing point and were much more complicated to use ...

Thermometer with PIC Microcontroller

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 time. In this tutorial we will make a practical use of multiplexed seven segment displays. We will use them to show current room tempe ...

Schematics and C code for a 0-5V PIC LCD Volt Meter. using pic microcontoller

This PIC LCD volt meter project uses a PIC micro and an HD44870 LCD display. The analogue input is taken directly to the analogue input pin of the microcontroller without any other processing. Specification Voltage range 0V - 5V Input signal level TTL Maximum input impedance 2k5 The LCD volt meter uses the microcontroller power supplies as reference voltages and so it is not likely to be very accurate (e.g. ...

Very Accurate LC Meter based on PIC16F628A

About Accurate LC Meter This is one of the most accurate and simplest LC inductance / capacitance Meters that one can find, yet one that you can easily build yourself. This LC Meter allows to measure incredibly small inductances starting from 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from 0.1pF up to 900nF. LC Meter's circuit uses an auto ranging system so that way you do not need to spend ...
