Likewise, to use One Wire device, define the parameter as given below.ĩ. For example, to enable use of servo with nanpy, define the parameter as given below. In Raspberry Pi, contents of the file can be edited using nano or Leafpad. This file has the option to add Arduino library options that are needed by setting the contents to 1. nanpy directory will show a file called cfg.h. Navigate to nanpy directory using the following command, followed by ls: Run this file by running the command given below.Ĩ. List the contents with a file called configure.sh. This will take you to nanpyfirmware directory. Enter the following command, followed by ls: Rename nanpy-firmware as nanpyfirmware.ħ. This will install nanpy firmware from Github in Downloads folder.Īt this stage if you use ls command, there will be two folders listed: nanpy and nanpy-firmware.

Enter the following command to install nanpy folder from Github in Raspberry Pi When you navigate to Downloads folder, the prompt will be as shown below.ĥ. It is a good idea to clear all contents from the folder.

Go to Downloads folder using cd command, as given below.ĭownloads folder may have other contents. Install Arduino IDE on Raspberry Pi, as given below.Ĥ. Enter the following command to install all updates on Raspberry Pi and have all packages up to date:ģ. Open Raspberry Pi terminal, and the prompt will open as given below.Ģ. Power on Raspberry Pi and connect it to the Internet using Wi-Fi or Ethernet. The steps for installing Nanpy on Raspberry Pi are given below.ġ. Writing a GUI with Tkinter to control Arduino onboard LED Installation of Nanpy on Raspberry Pi Installing Nanpy libraries on Raspberry Pi operating systemģ. Software development for this article is divided into three parts, as follows:ġ. 1, and block diagram of the project is shown in Fig. Hardware setup of the project is shown in Fig. (Note: Raspberry Pi 4 and Arduino Uno R3 boards were used during testing at EFY Labs.) Tkinter interface is used to build a graphical user interface (GUI) to control an I/O pin of Arduino. This article attempts to bring out the best of both the worlds by using computing power of both Arduino and Raspberry Pi that can achieve almost anything. This is because it is a 3.3V device and has no analogue channels.Īrduino, on the other hand, is a 5V device that can connect with field sensors, and has many analogue, PWM and digital I/O channels. Raspberry Pi, a credit-card-sized computer, has a good amount of computing power but lacks the ability to connect to field devices. Arduino as a slave can also be used to control electrical devices including LEDs and servos. The program presented here provides simple steps to interface Raspberry Pi and Arduino. This article describes the procedure to set up Arduino as a slave device, which gets all control signals from Raspberry Pi running a Python program.
