This JDM programmer works with a RS232, 9-pin(9 wire) DB9 Serial connector on your computer, and is used for loading Source Code (hex files) into your microcontroller. JDM programmers are Cheap and very easy to make. JDM programmer that we are going to make will be used for loading the code into microcontroller board. You can probably buy this JDM

Online or from some Electronic store but if you are going to make one for yourself then, total spending for all components and board will cost you less than half of the actual price of the JDM that you will get in any electronic store. This jdm programmer responds, or lets us to burn the program into the microcontroller chip through small software known as winpic800. Winpic800 is compatible with pic18f4550 and JDM serial programmer. It works with lot of other hardware too, which are similar to JDM programmer, like the [GTP-USB] but it costs around 60 ‚¬ from their official website. So it`s a good option for beginners to stay with JDM programmer as cheap alternative in the early stages. Later for a better programmer I recommended pickit3 from microchip which makes it easier to program with a USB port. As of now with this JDM programmer we are going to program PIC18F4550 USB Interface Board for FIRST TIME BURNING OF CODE INTO THE CHIP This JDM programmer uses RS232 DB9 port to program the code into the microcontroller. I recommend do not use a laptop for JDM programmer. Usually now a days laptop`s does not comes with a DB9 serial port, so if you are thinking to use a USB to DB9 converter cable for doing this job then its a bad idea. Don`t even think about USB to DB9 converter, it just won`t work. So I recommend use a Desktop Computer which comes with an inbuilt DB9 Serial port. If you are thinking of a USB programmer then...
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....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
