Added a BASIC preprocessor made in python that allows you to write code withought line numbers and to use labels. the preprocessor adds the lines and changes the labels to line numbers. Also made an AmericanFootball BASIC game, as an example of how to use the preprocessor. Also made some small changes to the firmware, so make sure to update that t

oo. May 10 2012: Fixed a bug that allowed only 127 lines of BASIC in one program, now allows 255 lines, I will increase this number when I get a chance. AmericanFootball. BAS now works, I have finally tested it. Update all your files! I did not use this, but you may consider using this hack to connect an SD card using a 5. 25 inch floppy disk connector: WARNING, the SDcard library does not use a FAT file system. so any data you may have on the SD card will be lost. you will need to reformat the SD card to use it again on a PC. I realize that few people will use the LCD module I used(which is a rare Japanese one), if someone uses a normal LCD remove the driver for mine, and replace all the print2nl() and print2 with lcd. print and lcd. printnl and send me a copy of the working sketch to usmpadow@gmail. com so I can put it up with this project. L# GOSUB L# - goes to the line number specified and will return to the next line when a RETURN is encountered (it seems this might be buggy too. I will try to fix it) Upload the SDmemBASIC. ino sketch to the arudino. Use a terminal program like Tera Term, connect to your arduino(if it is terraterm, set the wait to 20ms for each char and 200ms for each line in setup=>Serial Port) this one only uses the SD card, and the Serial Terminal to communicate, no LCD screen required: this one uses RAM, so you only need an arduino, no SD card or LCD screen, the BASIC programs are very restricted...
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.....
