Personal Radar System using PIC MIcrocontroller PIC18f452 is a microcontroller hobby project. The circuit diagram of radar is attached here below seemed a little bit simple schematic but you need careful reading of PIC18f452 radar circuit to avoid any.... -
FT232RL USB to Serial UART (TTL) Adapter is a simple and inexpensive way to connect PIC, AVR or ATMEGA MCUs to a PC or Mac via USB connection. FT232RL is an impressive chip because it implements full v2. 0 USB protocol, needs no external crystal, has.... -
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.... -
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.... -
Connect Relay with pic microcontroller and whenever I put Load on Relay`s Contacts PIC16f877a resets. I some time solve this problem by triggering another relay from basic relay attached to PIC. But this is not a solution. Can any one describes Why pic is.... -
PIC controlled 500W `Modified Sine Wave` Inverter. The PIC16F628A is programmed to produce a logic 5v signal for 5ms at pin 17 then 15ms off.... -
buzzer circuit, pic microcontroller, piezo buzzer is a computer chip. It is overkill for driving a piezo buzzer. It is certainly a very low power processor that is optimum for portable and small devices where battery power must be conserved.... -
In present day, variety good sensors are available to measure almost anything. In this tutorial will explore the wonderful world of sensors, starting with a very simple analog temperature sensor LM35. We will learn how to interface it with PIC MCU and.... -
We will use them to show current room temperature using a LM35 temperature sensor. Please note that this schematic is slightly different from our previous schematic on multiplexed seven segment display. The display select i/o pins were RA0, RA1, RA2, RA3 on.... -
Remotly check the temperature of a few things, in my case the repeater site at GB3PY. A system which used a radio to receive requests for the currenttemperature and send the results back to the user. Requests are by DTMF tones and the response is in CW,.... -
The transformer is a 220V to 12V, 50Hz and 3. 6VA PCB type transformer. The model seen in the photo is HRDiemen E3814056. Since it is encapsulated, the transformer is isolated from the external effects. A 250V 400mA glass fuse is used to protect the circuit.... -
This is a Simple com port based Microchip PIC microcontroller Programmer, This Programmer is based on JDM programmer. The entire programmer is built around commonly available components you can programe may microcontroller by using this schematic, all you.... -
A small biped walker made of 2mm plywood. Powered by two RC servos. it is a popular microcontroller, easily available and programmable now as flash microcontroller 16F84. This simple circuit can be used to program the PIC16F84 and similar "flash memory" type.... -
hi am trying to make a pic based inverter circuit. the circuit uses 2 p-channel mosfets(f9540n) with a centre tapped 12-012/230v transformer. i.... -

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
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.... -
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.... -
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.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
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,.... -
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.... -
