A look at the ESP32

I'm a big fan of the ESP8266 devices that are available so when I saw that there was an ESP32 available I was interested to have a look.

Linkit One and MMA7361 example

The MMA7361L is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, 0g-Detect which detects linear freefall, and g-Select which allows…

Linkit One and ADXL335 accelerometer example

The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. It can measure the static acceleration of gravity in…

Linkit One and PCF8574 example

The PCF8574 is an 8 bits I/O port expander that uses the I2C protocol. Using this IC, you can use only the SDA and SCL pins of your Linkit One board to control up to 8 digital I/O ports.

Linkit One and AD Keypad example

I purchased this module as part of a microcontroller kit, its an interesting little module as it has 16 buttons but with only 1 I/O line is required, an analog input. You connect this to your Arduino and read in the value. The concept is…

Linkit One and SHT11 example

The SHT1x digital humidity sensor is a reflow solderable sensor. The SHT1x series consists of a low-cost version with the SHT10 humidity sensor, a standard version with the SHT11 humidity sensor, and a high-end version with the SHT15…
