![]() ![]() Templating with an If Statement to create a new senso the valuetemplate would not. Add an additional case to the switch case statement that will turn on all the LEDs with one keystroke. If you can feed your template sensors to Utility Meters and use the. You will have to expand the map() range to do this. Turn temperature reading into morse numbers. Add an additional case to the switch case statement. The Serial print is only in the code to allow me to debug, it will not be in the finished project. Can anyone suggest a slimmed down method please. I have got as far as doing this with an if statement but I feel sure that there must be a way of avoiding another 50 lines of the similar code. It will then select the matching case, and run the code listed under it before returning to the top and looping through the code again. When using a switch case, the program will take a variable, in the example below it is range, and compare it to several cases. For example if the temperature is 22 degrees the LED will flash the number two twice. A switch case statement is used in place of multiple if statements. Because it is not in the main loop, I am having trouble getting the 4 LEDs to switch on and off. I need help with a few things I need help with blinking 4 of the LEDs continuously with 100ms pause in case 1. The temperature range will be from minus 15 degrees to plus 40 degrees and my intention is to flash an LED for each degree. In each case statement, there will be different LED functions. The ballast will be dimmed over a 1-10v port through PWM pin 9 (NPN transistor, capacitor, and some resistors). I am using three on/off switches and based on the truth table would like to turn on one of 8 LEDs. Hi guys, I’m trying to program an Arduino to control ultrasonic sensor which functions as a base to driver a 2 channel solid state relais (low lvl trigger), piezo buzzer and a ballast. I have been looking for a way of avoiding over 50 lines of if/else or switch case statements without success. arduino uno - Multiple if statement conditions - Arduino Stack Exchange Multiple if statement conditions Asked 8 years ago Modified 3 years, 7 months ago Viewed 40k times 3 I would like to make this code using the Arduino Uno. Switch allows you to choose between several discrete options. As it turns out, however, this logic will produce. When there are more than two options, you can use multiple if statements, or you can use the switch statement. I am trying to convert the reading from a TMP36 temperature sensor to Morse code numbers sent from an LED. When an obstacle is detected, switch to the avoid-obstacles behavior until the obstacle is no longer detected. ![]()
