How to build a HomeKit / Siri controlled election lock with ESPea and Relay shield. It’s a cheap project for smart lock. I built a custom HomeKit / Siri controlled election lock recently. It need ESP8266/NodeMCU, Raspberry PI and a Electric Lock 12V DC. See more information at the instructableDetails
BMP280 shield for ESPea. The BMP280 sensor can measure barometric pressure and temperature with very good accuracy. This shield is good match with ESPea, ESPea32. It also has nice size. Buy Link ESPea Relay Shield for ESPea. This is the ESPea Relay Shield, an add-on board that allows your ESPea to control higher voltage and current loads…Details
128×64 pixels OLED Shield with I2C. It adds a 128×64 monochrome OLED to ESPea main board. The OLED uses only the two I2C pins on the ESPea, and you can pretty much stack it with ESPea, even ones that use I2C since that is a shared bus. Buy Link. Prototype Shield For ESPea is also…Details
