After an LCD workout you`ll find LED segments pretty easy to drive, so don`t worry too much about the programming! That 20M circuit shown above has code => & schematic => Tec- excuse these boring Q`s, but they`ll help us to better appreciate your quest. This esteemed forum receives many educational calls for help (including some just hours before a submission deadline. ) &

the classic things we REALLY need to know include - Your age Where are you Experience Resources Facilities Budget Time frame What academic course How assessed Help allowed Project presentation needs - PCB Documentation needed Mmm- perhaps even your profs. background! After an LCD workout you`ll find LED segments pretty easy to drive, so don`t worry too much about the programming! That 20M circuit shown above has code => & schematic => well im 20. and i will be graduating on the 5th with a degree in Electronics Technology. so im loosing all of my access to the lab`s there is a chance that i will still be able to keep in touch with my professors through the internets. but i do have my own work room in my basement with power supplies, o scopes and other various tools. Remember when you were 7 and every time you had to look at your kitchen wall clock you had to count to know the exact time i. e. small needle @ 7 and bigger needle @ 6. You also had to learn it, so you could interpret that it was actually 7:30. Back in 1989 I did a fairly extensive alarm clock design with the Motorola 68705 microprocessor which used the power line (mains) frequency as a timebase. It, too, used a multiplexed LED display, with the MPU doing the multiplexing. The result appeared in my article "68705 Microcontroller, " Radio-Electronics, October 1989, p. 83, 86-89. Many university libraries (at least in the US) have archived this on their shelves if...
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.....
