Objective Motion detection for light control or alarm trigger. Wiring Since we covered the basics in our previous posts adding another module is unspectacular from the circuit point of view. We will use our LCD circuit do demonstrate the output….

PIC16F18855/75 with DHT11
Temperature and Humidity sensor controlled by a PIC and displayed to an LCD for debugging. In the future the LCD may be replace, e.g., with a Bluetooth module and read by another system. The Wiring We base our example here…
PIC16F18855/75 with MCP23017 GPIO Extender
Even though some microcontrollers have a lot of GPIOs, sometimes one may find himself/herself in the need of even more. The MCP23017 is made for that purpose. In the previous post we learned how to setup a project to program…
20×4 LCD controlled by PIC16F18855/75 using LCM1602 IIC/I2C
We’ve already done some projects with Rasperry Pi. While Adruino and Raspberry Pi are great prototyping tools allowing fast development of proof of concepts, lot of resources, libraries and examples, it also comes with some pitfalls. In case of Raspberry…
