New PasswordPump2.0 Ensures You Never Forget a Password
https://www.electronics-lab.com/new-passwordpump2-0-ensures-never-forget-password/
Using the same password on different platforms can be a security risk, but remembering different passwords, used for different accounts, can be quite the task too especially with the need to infuse special characters and numbers, and the fact that you may not use some of the passwords regularly enough for them to become easy […]
Arduino-Based SSD uses an ATmega8 & 8 EEPROM chips
https://www.electronics-lab.com/arduino-based-ssd-uses-atmega8-8-eeprom-chips/
“Now, instead of using an SD card to store configuration files, I can simply send commands via the UART interface to the SSD from an external board and store/retrieve data without the extra code overhead.” SD cards are used for storing information when logging data or retrieving files but with microcontrollers that have shorter RAM […]
M95M04-DR – 4-Mbit serial SPI bus EEPROM
https://www.electronics-lab.com/m95m04-dr-4-mbit-serial-spi-bus-eeprom/
The M95M04 devices are electrically erasable programmable memories (EEPROMs) organized as 524288 x 8 bits, accessed through the SPI bus. The M95M04 can operate with a supply range from 1.8 to 5.5 V, and is guaranteed over the -40 °C/+85 °C temperature range. The M95M04 offer an additional page, named the Identification page (512 bytes). […]
How to Use I2C EEPROM with Arduino
https://www.electronics-lab.com/how-to-use-i2c-eeprom-with-arduino/
Expand your board’s storage with an I2C-enabled EEPROM chip. EEPROM stands for Electronically Erasable Programmable Read-Only Memory. It allows for values to be written and stored for long periods of time while using very little power. Most microcontrollers even have EEPROM directly in their circuitry, such as the ATmega328P (Arduino Uno chip), which has 1KB […]
Using ESP32’s Flash Memory for data storage
https://www.electronics-lab.com/using-esp32s-flash-memory-data-storage/
The ESP32 has about 4MB of internal flash memory and since the data stored within the flash memory is retained even when power is recycled, it becomes super useful for applications where you need to keep certain amount of data even after power off. For today’s tutorial, we will learn how to read and write […]
I2C Encoder V2 – Connect multiple rotary encoders on the I2C bus
https://www.electronics-lab.com/i2c-encoder-v2-connect-multiple-rotary-encoders-i2c-bus/
I2C Encoder V2 is a tiny smart board for connecting multiple rotary encoders on the I2C bus and it’s live on kickstarter. The I2C Encoder V2 supports various type of rotary encoder with one footprint: Standard mechanical encoder Illuminated RGB encoder Clickable rotary encoder With and without dent There are also 3 configurable GPIOs that […]
Interfacing Arduino with Micro SD card Module
https://www.electronics-lab.com/interfacing-arduino-micro-sd-card-module/
We published a new tutorial in partnership with Nik Koumaris from educ8s.tv. Often, we have the need for a way to store data in our projects, and most of the time, the EEPROM has not enough storage and the storage size is limited. It also has issues with the format and nature of data it […]
Writing to flash and EEPROM on the tinyAVR 1-series
https://www.electronics-lab.com/writing-flash-eeprom-tinyavr-1-series/
Update your tinyAVR code to access memories when using 1-series tinyAVRs. Link here (PDF) On tinyAVR® 1-series devices, access to Flash memory and EEPROM has been changed from that on previous tinyAVR devices. This means that existing code for writing to Flash and EEPROM on older devices must be modified in order to function properly […]
DS28EC20, A Serial 1-Wire 20Kb EEPROM
https://www.electronics-lab.com/ds28ec20-serial-1-wire-20kb-eeprom/
The American manufacturer of analog and mixed-signal integrated circuits, Maxim Integrated, has developed a new serial EEPROM memory that operates from single-contact 1-wire interface. The DS28EC20 is a 20480-bit, 1-Wire® EEPROM organized as 80 memory pages of 256 bits each. An additional page is set aside for control functions. Data is written to a 32-byte […]
Analog front-end IC linearizes sensors
https://www.electronics-lab.com/analog-front-end-ic-linearizes-sensors/
Susan Nordyk @ edn.com discuss about LTC2986 which is able to digitize and linearize a combination of temperature sensors in Celsius or Fahrenheit degrees. A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples, RTDs, thermistors, and external diodes with 0.1°C accuracy and 0.001°C resolution. The analog front-end device combines […]
