The frequency of a 555 timer in astable mode can be expressed as a function of the capacitor C and resistors R1 and R2. The formula for the frequency is: f = 1....

 Also ard app hidden?  got to find & delete Got it working again after several ReInstalls Open a terminal and run:  find -iname "ardu*" This will show you all files and directories with "ardu" in the name 1 . ____________________________________ The recommended method for installing the ESP32 library on Arduino IDE is as follows: ## Step 1: Install Arduino IDE Ensure you have the latest version of Arduino IDE installed on your computer. You can download it from the official Arduino website[1]. ## Step 2: Add ESP32 Board URL 1. Open Arduino IDE 2. Go to File > Preferences 3. In the "Additional Board Manager URLs" field, enter:    https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json 4. Click "OK" to save the preferences[1][3] ## Step 3: Install ESP32 Board 1. Go to Tools > Board > Boards Manager 2. Search for "ESP32" 3. Find "ESP32 by Espressif Systems" and click the "Inst...

11/23 still NAN... will try other modules try other sketches with UNO instead NANO  Reads NAN but runs 112024_oled_AM2320_drone OLED working fine Addes 10k pukkups...no good! ---------------------------------------------------- 112024_dht11_oled_copy_20241122192617 OLED working with DHT11.. printing ok OLED Need to ck code on 2320 & understand why it sends NAN Graph temp show some history

 11/22 Excellent Vid & hes using Falstad https://www.youtube.com/watch?v=O7hkxXEA3K8&t=2267s

 Enter to go to Menu2 Still need to add Electronics Blog and Notes and James Mize

 Got two of the digital set to turn "ON: Drops output >1000 to below 200 Will use to trigger directional sound Got it kinda working BB002  112024_2_mics_dir_copy_20241120130140 Descent vid https://www.youtube.com/watch?v=bMs5J4bJOD0&t=5s Need to play with Threshold setting (2?) And sensitivity on mics May need to test other mics

 Check Device Mgr for Port ( not always shown in IDE..prob 4 Nano

 Now to get them working together... No luck with contactless level sensor Started TICTAC Brocode - RockSessors done& posted to Mize

 still need doc 

 Setting up to test 3 mics ... using https://www.youtube.com/watch?v=RwHGioglbk8&t=93s  I can use this prgm to use train noise to .... not sure about direction.. set R/L thresholds separately

Understanding the winning code in Challenges Perplexity BIG help

 been testn  various versions for RR applic None working very well got one more test with Mic that has both d & A outputs https://www.youtube.com/watch?v=RwHGioglbk8

These sensors output continuous voltage levels, which the Arduino can read using its built-in Analog-to-Digital Converter (ADC). Below is a list of common analog sensors that can be used with Arduino: ****Light Sensors**** - **Photoresistor (LDR)**: This sensor changes resistance based on light intensity, allowing it to measure ambient light levels. ****Temperature Sensors**** - **KY-013 Temperature Sensor**: An analog temperature sensor that uses an NTC thermistor to measure temperatures from -55°C to +155°C. - **LM35 Temperature Sensor**: Outputs a voltage proportional to the temperature in Celsius. ****Motion and Proximity Sensors**** - **Ultrasonic Sensor**: While primarily digital, some models offer analog outputs for distance measurement. - **PIR Motion S...

 Decided to use challenges to advance JS instead of tuts Found a few online that are free with solutions

 Added Electronics in a big way my Arduino & JS Triad.  Order new Maker Books and use Mims.  The Electonics adds a thinking/ problems solving element.  Falstad is easy to use and the current flow and charts add much. JS use Bro for easy lessons. Ard working mics... a lot more to mics than I thought.  Quick use for trains. Need to buy an R4 wifi... does WIFI extent to tracks?

 Finished sketch LED lights depending on loudness.  Wasnt working.  Testing various mics.  Using my Osc to confirm voltage generated.   Need to review sketch for Loudness trigger ponts. https://www.youtube.com/watch?v=bMs5J4bJOD0 The Electret Microphone Amplifie triggers based upon set point.. Digital Keys KY 038 results in analog wave form = 1/2 3.3V...enough to trigger with voice I have these uses; light leds a f loudness tell direction train 100mv  100ms Got the 5 LED Loudness board working.  Had to play with setpoints and delays.

DirSnd   Not working.  Need to test Sound Devices separatly to determine kind of response Digital or Analog? Got sensor working.  Now have to test sketch.

 Ran Blink test Plan on using with Sound (from Train)
