I once simulated a LoRa-based weather station on Wokwi, pairing an ESP32 with a BME280 sensor in MicroPython. It nailed the data pipeline, catching a timing bug that would’ve wrecked my hardware tests. Compared to Tinkercad, Wokwi’s ESP32 support let me push boundaries, though I crave...
// put your setup code here, to run once: Serial.begin(br); myDHT.begin(); delay(setUpDelay); } void loop() { // put your main code here, to run repeatedly: tempC=myDHT.readTemperature(false); tempF=myDHT.readTemperature(true); hum=myDHT.readHumidity(); if (isnan(tempC) |...
Possible actions for keys and menu functionsUI_ACTION_NEXT : Next higher value/menu entry UI_ACTION_PREVIOUS : Previous lower value/menu entry UI_ACTION_X_UP : Move x axis 1 mm right UI_ACTION_X_DOWN : Move X axis 1 mm left UI_ACTION_Y_UP : Move Y axis 1 mm to front UI_...
You may find it convenient to create functions to send the data. Here is a function that uses the code shown earlier to print a 16-bit integer to the serial port: // function to send the given integer value to the serial port void sendBinary(int value) { // send the two bytes that...
That is the Machine part. Every time through the loop we ‘run the machine’ and the machine takes care of updating the state.Next, we'll look at how you can combine multiple state machines and run them concurrently.Now for two at once Now it is time to do some multi-tasking! First...
// put your setup code here, to run once: Serial.begin(9600); pinMode(butPin, INPUT_PULLUP); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); oled.begin(SSD1306_SWITCHCAPVCC, SCREEN_ADDRESS); oled.clearDisplay(); oled.display(); } void loop() { // put your main code here,...
void loop() { // iterative FOC function motor.loopFOC(); // iterative function setting and calculating the angle/position loop // this function can be run at much lower frequency than loopFOC function motor.move(target_voltage); } Now we are able to read the two encoders and set the...
Serial.println (encoder0Pos, DEC);// debug - remember to comment out// before final program run// you don't want serial slowing down your program if not needed}/* to read the other two transitions - just use another attachInterrupt() ...
information is returned by the setup, more on this later. The two brackets are used in every function, to pass data through; setup doesn't need any data, so the brackets are empty. Don't worry if you don't understand this yet, we'll cover it in detail in the step about functions....
The UART layer makes them easy to use but hides the Bluetooth functions from the user. This is good if all you want is to make 2 things talk to each other. The HC-05 has two modes of operation; AT command mode and transmission mode. When in AT command mode all data received over ...
