Everything started with the fact that the MT-5 display wasn’t what I really needed. I was in the need of checking the charging from the device using the battery: my trusty Raspberry pi (1 B at the time). I managed to stumble over this instructable (http://www.instructables.com/id/Use-Arduino-to-Com… and git project (https://github.com/xxv/tracer/). So the code and research …
Here’s a diagram I did today for the interface between the photodiode and the Raspberry Pi. First, the photodiode allows small amounts of current to flow when light is shone on the device. this current is amplified by the BJT (so, just a normal transistor really) and a proportional voltage is produced across R2. This is fed …
Raspberry Pi has a Broadcom BCM2835 chip, which controls 26 GPIO (general purpose input/output) pins. There are C library or RPi.GPIO python package available online that can be used to control the pins. The RPi.GPIO package is by default included in most Raspberry Pi system, such as Raspbian, a RPi version of Debian linux system. One …
you can go directly to Section 9 also. make high quality brain wave interface as low cost and small size is my over 20 years of dream. To do so need mass production, need work with investor to realize that way. not just only my thinking many people ask me to have low cost brain …
The circuit uses a SC16C650 to implement an IrDA interface. Infrared Data Association (IrDA) has defined a group of short-range, high speed, bidirectional wireless infrared protocols, generically referred to as IrDA. The hardware section is composed of SC16C650 which is electrically hooked-up to an IrDA transceiver module. The electrical connection between the SC16C650 and an …
Description This project provides you a simple and easy solution to connect / convert your Microcontroller input/output to be connected to the serial port of the Computer. This projects build around popular MAX232 level shifter IC to do the Level Shifting (Voltage) between 5 V and 12 V DC. An Onboard 9 pin female D …
Yes,we learned that we can take mobile phone camera modules from almost all mobile phones to inteface them with our advanced hobby electronics projects just as with any other standard add-on modules. Since this calls for an appropriate microcontroller, it is better to use Arduino or Raspberry Pi microcontroller as a utile platform. Raspberry Pi …
I have a driveway that is over 300 feet long and it is nice to have some advance notice that someone is driving or walking in. Previously, I have used a very expensive IR beam-break detector. It gave a lot of false alarms and eventually failed due to a lightning strike. It also required that …
Here is another somewhat larger interface shown connected to a switch unit and a 16 LED output board. As the Pi connector does not have 20 GPIO pins, three of the pins are shared and can be connected to be either input or output via tree links. I designed the pin-out of this interface so …
