Learn soldering and programming with the Arduino Make Your UNO Kit

Arduino Make Your UNO Kit is a kit with two boards, one for the microcontroller and the other for audio, and all components required that can be used to learn how to solder and then Arduino programming. Once soldering and assembly are complete you’ll hopefully get a working Arduino UNO and an audio synthesizer shield. But before you get there, you’ll need to equip yourself with a soldering iron and some soldering tin to solder the components below to the two PCBs.

LOLIN C3 Pico is a tiny ESP32-C3 board with battery charging support

LOLIN C3 Pico is a tiny (25.4×25.4mm) ESP32-C3 RISC-V board with 2.4 GHz WiFi and Bluetooth Low Energy connectivity, a few I/Os, and LiPo battery support including charging circuitry. I tend to like Wemos/LOLIN boards, because of their small form factor, support for equally tiny shields, and low price. The LOLIN C3 Pico is no exception, and even adds a few features such as an RGB LED, an I2C connector, and support for battery power and charging. LOLIN C3 Pico specifications: SoC – Espressif Systems ESP32-C3FH4 single-core 32-bit RISC-V (RV32IMC) microcontroller up to 160 MHz with 400 KB SRAM, 4MB Flash Connectivity – 2.4 GHz WiFi 4 and Bluetooth 5.0 LE (in SoC) Expansion headers 2x 8-pin headers with up to 12x GPIO, ADC, I2C, SPI, UART (3.3V I/O voltage) LOLIN I2C port USB – 1x Type-C USB for 5V power and programming Misc – Reset button and user button, […]

Easily add face detection to your project with the Person Sensor module

It’s now much easier to AI features to your project thanks to better tools, but as we’ve experienced when trying out Edge Impulse machine learning platform on the XIAO BLE Sense board, it still requires some effort and the learning curve may be higher than some expect. But for common tasks like face detection, there’s no reason for the solution to be hard-to-use or expensive, and Pete Warden (Useful Sensors) has designed the $10 Person Sensor fitted with a camera module pre-programmed with algorithms that detect nearby faces and reports the results over an I2C interface. Person Sensor specifications: ASIC – Himax HX6537-A ultra-low-power AI accelerator @ 400 MHz with 2MB SRAM, 2MB flash Camera Image Sensor – 110 degrees FOV Image scan rate – 7Hz with no facial recognition Image scan rate – 5Hz with facial recognition active Host interface Qwiic connector for the I2C interface up to […]

T-Dongle-S3 USB dongle combines ESP32-S3 wireless MCU with optional color display

LilyGO T-Dongle-S3 is a USB dongle based on ESP32-S3 dual-core microcontroller with WiFi 4 and Bluetooth 5.0 connectivity, a microSD card slot, as well as an optional 0.96-inch color display. You may remember the company launched the T-Dongle ESP32-S2 last spring, and I first thought it was an update to ESP32-S3, but the new T-Dongle-S3 has quite more compact design and a smaller set of features that makes it suitable for data logging and displaying basic information over a wireless connection. T-Dongle ESP32-S2 development board specifications: Wireless SoC – Espressif Systems ESP32-S3 with Dual-core 32-bit Xtensa LX7 microcontroller up to 240MHz RISC-V ULP Co-processor 512KB SRAM 2.4GHz Wifi 4 (802.11b/g/n) Bluetooth 5.0 BLE + Mesh Storage 4 MB flash (or 16MB flash depending on where you look) MicroSD card socket cleverly “hidden” under the USB connector Display – Optional 0.96-inch 65K color IPS LCD (ST7735 SPI controller) with 160 x […]

Making a weather station with Maker Pi Pico Mini board and SparkFun SerLCD display

Cytron’s Maker Pi Pico Mini comes with a Raspberry Pi Pico or Raspberry Pi Pico W microcontroller board. It has the same features as the larger Maker Pi Pico including a GPIO LED, WS2812B Neopixel RGB LED, a passive piezo buzzer, programmable push buttons, and a reset button. I would like to thank Cytron for sending the Maker Pi Pico Mini board fitted with a Raspberry Pi Pico W as well as a character RGB LCD and a 3.7V Lithium Polymer battery. In this tutorial, we will show how to make an Internet connected weather station with the Maker Pi Pico Mini board using Arduino code and the OpenWeather API. We’ve already covered the Maker Pi Pico Mini board, so we’ll have a closer look at the accessories SparkFun SerLCD character display The SparkFun SerLCD is a 16×2 character display with a Microchip ATmega328P microcontroller that handles commands sent from […]
