Blink an LED on ESP32 board with Tuya Link SDK

Tuya is an All-in-one IoT Platform that enables the user to build smart IoT solutions by connecting devices efficiently, securely, and reliably. This is a getting started article to set up the Tuya platform with the Espressif’s ESP32 boards via tuya link SDK. Further, we use it to control an LED through an Android device. When the switch in the Tuya Smart App is turned ON, the LED connected to the ESP32 board glows and vice versa. Prerequisites Hardware: ESP32 board LED with suitable ballast resistor Breadboard, micro-USB cable, and connecting wires Software: Tuya Account: Tuya IoT Platform (Web) Tuya Account: Tuya Smart Application (Android) Python 3.x Arduino IDE GitHub Link: https://github.com/JayeshRajam/Tuya-ledapp.git Hardware Connections for Tuya Link SDK The ESP32 board is placed on a breadboard. The positive terminal of the LED is connected to digital pin 5 of the ESP32 board and the negative terminal is connected to the […]

PicoVoice offline Voice AI engine gets free tier for up to 3 users

PicoVoice offline Voice AI engine has now a free tier that allows people to create custom wake words and voice commands easily for up to three users on any hardware including Raspberry Pi and Arduino boards. I first learned about PicoVoice about a year ago when the offline voice AI engine was showcased on a Raspberry Pi fitted with ReSpeaker 4-mic array to showcase the company’s Porcupine custom wake word engine, and Rhino Speech-to-Intent engine. The demo would support 9 wake words with Alexa, Bumblebee, Computer, Hey Google, Hey Siri, Jarvis, Picovoice, Porcupine, and Terminator. More importantly, the solution allows you to easily create your own custom words in minutes from a web interface by simply typing the selected wake word, with no need for hundreds of voice samples or waiting weeks to get it done. So I tried “Hey You” first, but I was told it was too short, […]

Seeed XIAO BLE – A tiny nRF52840 Bluetooth 5.0 board with (optional) IMU sensor and microphone

Seeed Studio has just introduced two new members to their XIAO board family with the Seeed XIAO BLE and XIAO BLE Sense boards equipped with Nordic Semi nRF52840 Bluetooth 5.0 microcontroller, as well as an IMU sensor and microphone on the “Sense” model. Just like the earlier XIAO RP2040 board, the tiny Seed XIAO BLE board can be programmed with Arduino, MicroPython, and CircuityPython, and offers two headers with 7-pin each for GPIOs. What’s really new is the wireless connectivity, the sensors, and a battery charging circuitry. Seeed XIAO BLE specifications: Wireless MCU – Nordic nRF52840 Arm Cortex-M4F microcontroller @ up to 64 MHz with 1 MB flash, 256 KB SRAM, Bluetooth 5.0, NFC, Zigbee connectivity Storage – 2 MB QSPI flash Expansion I/Os 2x 7-pin headers with 1x UART, 1x I2C, 1x SPI, 1x NFC, 1x SWD, 11x GPIO (PWM), 6x ADC 3.3V I/O voltage (not 5V tolerant) Sensors […]

Giveaway Week 2021 winners announced!

Giveaway Week 2021 is now over, and I’m ready to announce the winners. This year, CNX Software was joined by Rakwireless and Shenzhen Xunlong Software, as I did not have enough hardware to send out. I also had planned to give away Crowbits Master Kit, but when I realized the ESP32 module had a battery, I would have had to ask $100 just for shipping, plus having the risk of messing things up, since I’ve never sent devices with batteries with the new regulations. Nevertheless, the void was filled thanks to the generosity of Rakwireless who offered a solar-powered LoRa GPS tracker, and Shenzhen Xunlong Software who proposed an Orange Pi R1 SBC with a plastic enclosure. Let’s go through the list of winners located in four continents with Europe, North America, Asia, and Oceania represented: NanoPi R2S gateway – Jason, CANADA WisBlock Kit 2 LoRa-based GPS Tracker with Solar […]

Giveaway Week – Arduino Sensor Kit Base

Day 6 of giveaway week 2021 will be for the Arduino Sensor Kit Base, a large board with six Arduino modules with Grove connector plus an Arduino shield with Grove connector. You could use it directly on top of an Arduino UNO or compatible to have a massive shield with multiple modules connected with Grove cable, or you could break it out into smaller modules as you see fit. The kit ships in a protective carrying plastic case with six Grove cables to connect the six Arduino modules to the Grove shield in the middle of the board. I told Seeed Studio I would not have time to review it, but they still sent it to me last December. So I’m here with a kit that I’m probably never going to use so better just give it away. You can enter the draw by simply leaving a comment with your […]
