pic RN-41 bluetooth module not transmitting data
Connect a pic to an rn-41 bluetooth module. I`m not the person who designed the PCB, so I can`t answer exactly why the circuit is the way that it is instead of using the voltage divider used by some other people. Basically, the 5v logic from the pic is used to control transistors which are connected to a 3. 3v source (converting it to
How to Wire a PIC Microcontroller
I managed to program my PIC 16f627 to turn on three LEDs when push button (trigger button) is pressed and start a shut down sequence (basically each LED toggles off one after another with a 5 second delay in between) when another pushbutton is pressed (reset button). I`ve been testing this on a Velleman`s K8048 PIC Programmer/ Experimentat

Discolight effect with bass beat control using PIC
The PIC can control the motor after every beat or its possible to bypass some beats. It can be done by pushbuttons. Rotation speed and rotation length can be adjusted too. Settings are limited between values to prevent possible register overflow-underflow. These values are saved in EEPROM so after shut-down the settings dont lost. A beat consist o
Digital Slave Flash Trigger PIC 12F675
The Slave Flash Trigger is switched on/off by pressing the push button. When switched on, one to three flickers of the indicator lamp signalizes the programmed mode. One flicker determines that the flash will be fired at each flash. Two flickers indicate that the flash is fired at the second flash. Three flickers mean that the external flash is fi
LCD Frequency Counter Using PIC
PIC Freq Counter
A prescaler attached to a PIC to get a simple frequency counter. I would suspect that it would just become a "module" that I include in some other design projects later. Initially I need to get a working sample. Target range would be 1mhz through 400mhz.
Simple Universal PIC Programmer circuit
This simple programmer will accept any device that`s supported by software. The circuit is based in part on the ISP header described in the SILICON CHIP "PIC Testbed" project but also features an external programming voltage supply for laptops and for other situations where the voltage present on the RS232 port is insufficient. This is done...
Connect to the PIC Microcontroller
It is all very well knowing how to program the PIC in theory, but the real learning comes when you try your code on a PIC and see the results yourself in a circuit. You could build a circuit each time and program the PIC to see if the program works, or you can make yourself a development board. A development board allows you to simulate the...
Frequency Counter with PIC Microcontroller
If you need more sensitivity, use 74AC04 or 74HC04 instead of 74HCU04 as U1. It may be better than 74HCU04, but the frequency response of 74HC04 may be worse.
PIC USB Interface
The second program just sends "Hello world" to the PC. By default my board uses the Virtual COM Port (VCP) driver so you can view the output using Hyperterminal or similar program, I recommend PuTTY. The setup is quite simple, when I plug the PCB into my PC, it installs as COM3: (it will be different on your PC). In the terminal program you...

Ultrasonic distance finder circuit
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to find something potentially valuable, hidden a few centimeters below the soil. So many...
Fully automatic watering circuit for flower pots
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This circuit comes as a solution to this problem. Depending on humidity of the pot at...

Sub-Harmonic Bass Converter for Electric Guitars
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the calibration of the rope. This arrangement still exists in some yachts. The big...

Analogue Sound Preasure dB-Meter Circuit
The best human ear can capture sounds from 20Hz to 20KHz. These limits are known to be the broadest that can exist. Normally the normal limits range from 100Hz to about 13KHz and depend on the age and health of the individual. We for our measurements and to have a good accuracy we will get the limits of 20Hz to 20KHz. A sound to be heard does...
