I was wondering if anyone could help with direction on making my idea a reality. I would like to wire the remote control of an RC car to the GPIO pins of the Raspberry Pi. I just do not know how to "make the connection" between the GPIOs on the Raspberry
Relays are very important in electronics because you can use them to turn on/off high-power devices like lamps or garage door motors with just a small DC voltage signal. You can use a microcontroller, such asArduino, to create the logic for when to turn your lamp on and off, then use ...
One of the most useful things you can do with anArduinois control higher voltage (120-240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch t...
Firmware is the backbone of any ESC; it’s the software that breathes life into these components, determining the range of settings you can tweak, the protocols it can communicate with, and the interface you’ll use to configure it. Each ESC firmware is only compatible to certain hardware. ...
Optocoupler/Isolator DIRECT CONNECTION This is the simplest way. This solution “almost always” works, but with some important warnings. Fig. 2. Direct connection between a 3.3V CMOS and a 5V TTL device is possible. First, when interfacing with TTL inputs, any “modern” CMOS output will ...
In 1972, I used near-IR LEDs and laser diodes to send and receive voice signals, through the air and through optical fibers. Later I experimented with two-way optocouplers made by taping a pair of LEDs together so they faced one another. In 1988, I tried LEDs as sunlight detectors. ...
Unfortunately the ST-LINK programmer device that you’ll use to program the STM32 uses a 20-pin JTAG connector (with SWD functionality). This connector is quite large and is not practical for smaller board designs. Instead, you can use a 20-pin to 10-pin adapter board such asthis on...
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino is an architecture that combines Atmel microcontroller family with standard hardware into a board with inbuilt bootloader for plug and play embedded programming.Arduino Softwarecomes with an IDE that help...
In this brief tutorial I have explained how to design a customized UPS circuit at home using ordinary components such as a few NAND ICs and a some relays.
