<\/figure><\/div>\n\n\nNew to the Raspberry Pi Pico?<\/strong> Read the following guide: Getting Started with Raspberry Pi Pico (and Pico W)<\/a>.<\/p>\n\n\n\n Before proceeding, make sure you check the following prerequisites:<\/p>\n\n\n\n To follow this tutorial you need MicroPython firmware installed in your Raspberry Pi Pico board. You also need an IDE to write and upload the code to your board.<\/p>\n\n\n The recommended MicroPython IDE for the Raspberry Pi Pico is Thonny IDE. Follow the next tutorial to learn how to install Thonny IDE, flash MicroPython firmware, and upload code to the board.<\/p>\n\n\n\n Alternatively, if you like programming using VS Code, you can start with the following tutorial:<\/p>\n\n\n\n \u201cWhatsApp Messenger, or simply WhatsApp, is an internationally available American freeware, cross-platform centralized instant messaging and voice-over-IP service owned by Meta Platforms.\u201d It allows you to send messages using your phone\u2019s internet connection, so you can avoid SMS fees.<\/p>\n\n\n\n WhatsApp is free and is available for Android and iOS. Install WhatsApp on your smartphone if you don\u2019t have it already.<\/p>\n\n\n\n To send messages to your WhatsApp account with the Raspberry Pi Pico, we\u2019ll use a free API service called CallMeBot. You can learn more about CallMeBot at the following link:<\/p>\n\n\n\n Basically, it works as a gateway that allows you to send a message to yourself. All the information about how to send messages using the API can be found here<\/a>.<\/p>\n\n\n\n Before starting to use the API, you need to get the CallMeBot WhatsApp API key. Follow the next instructions (check this link<\/a> for the instructions on the official website).<\/p>\n\n\n\n 1)<\/strong> Add the phone number +34 611 01 16 37 to your Phone Contacts (name it as you wish);<\/p>\n\n\n\n Important: <\/strong> Please check the official instructions because the number might change without further notice.<\/strong><\/p>\n\n\n\n 2)<\/strong> Send the following message: \u201cI allow callmebot to send me messages<\/em>\u201d to the new Contact created (using WhatsApp of course);<\/p>\n\n\n\n 3)<\/strong> Wait until you receive the message \u201cAPI Activated for your phone number. Your APIKEY is XXXXXX\u201d from the bot.<\/p>\n\n\n Note:<\/strong> if you don\u2019t receive the API key in 2 minutes, please try again after 24hs. The WhatsApp message from the bot will contain the API key needed to send messages using the API. Additionally, double-check that you’re sending the message to the right number (check the number on the official page here<\/a>).<\/p>\n\n\n\n To send a message using the CallMeBot API you need to make a request to the following URL (but using your information):<\/p>\n\n\n\n For the official documentation, you can check the following link:<\/p>\n\n\n\n To send messages to your WhatsApp account, the Raspberry Pi Pico needs to send a request to the URL we\u2019ve seen previously.<\/p>\n\n\n\n The following code sends a test message to your account when you run the code.<\/p>\n\n\n View raw code<\/a><\/p>\n\n\n\n You need to insert your network credentials, phone number, and CallMeBot API key to make it work.<\/p>\n\n\n\n Let’s take a quick look at how the code works. Alternatively, you can skip to the demonstration <\/a>section.<\/p>\n\n\n\n We start by including the required libraries.<\/p>\n\n\n\n Insert your network credentials in the following variables so that the Pico can connect to your local network to access the internet.<\/p>\n\n\n\n Insert your phone number in international format (including the + sign<\/strong>) in the following line:<\/p>\n\n\n\n Example:<\/p>\n\n\n\n Then, insert the CallMeBot API key you\u2019ve got previously.<\/p>\n\n\n\n We create a function called init_wifi()<\/span> to connect the Pi to your local network.<\/p>\n\n\n\n To make it easier to adapt the code for future projects, we created a function called send_message()<\/span> that contains all the necessary instructions to send messages to WhatsApp. This function accepts as arguments the phone number, CallMeBot API key, and the message you want to send. You just need to call this function with the required arguments when you want to send a message.<\/p>\n\n\n\n Now that we\u2019ve created all the necessary functions, call the init_wifi()<\/span> function to connect the Pico to your local network.<\/p>\n\n\n\n We created a variable called message<\/span> that contains the text that we want to send. The message should be in URL-encoded format. You can use this tool<\/a> to convert your text to URL-encoded format.<\/p>\n\n\n\n Finally, call the send_message()<\/span> function to send the message.<\/p>\n\n\n\n After inserting your network credentials, WhatsApp number, and CallMeBot API key, run the previous code on your Raspberry Pi Pico.<\/p>\n\n\n\n If everything goes as expected, it should connect to the internet and make a successful request.<\/p>\n\n\n After a few seconds, you should receive a new message on your WhatsApp account.<\/p>\n\n\n In this tutorial, you learned how to send messages to your WhatsApp account by making a request to the callmebot API. We’ve shown you how to send a simple text message.<\/p>\n\n\n\n You can easily modify this example to send sensor readings or alert messages, for example. We have several getting started tutorials for basic sensors that you may find useful:<\/p>\n\n\n\n If you would like to learn more about the Raspberry Pi Pico, make sure to take a look at our resources:<\/p>\n\n\n\n In this guide, you\u2019ll learn how to send messages to WhatsApp with the Raspberry Pi Pico using a free API CallMeBot. This can be useful to receive notifications from your … <\/p>\nTable of Contents<\/h2>\n\n\n\n
