Hello, dear friend, can this module be trusted as a dc to dc 3.7v to 9v converter for the vc97 multimeter as its power supply, is there a need for a 9.5v zener to protect against output fluctuations? Is it possible to save the battery and put the module to sleep when the multimeter is off?
Is it possible to program esp32 devkitc with wroom32u on it You see when I connect the devkit to the computer it doesnt recognise it, but I can see the module when I scan wifi So the wroom works but cs2102 doesnt. Which pins do I need to connect to ftdi Thank you
do not use tp4056 to charge multiple batteries its not safe even for one, ii used it for 2 battries ,board just melted in 10 min i was there so i took it out very fast just think you put it charge went some where for few hours it will catch fire or destroy your battery its get extremaly hot just charging one battery this thing is trash and unsafe
Hi, I can give clarity on why I am using the relay instead of the motor driver. Normal l293d and l298n motor drivers can support up to max 2.5A load , we cannot connect the high amps load motors to these motor drivers. So I am using relays for motor direction and IRFZ44N MOSFET for voltage control for motor speed.
Those who doesn't work the code Take this code it work with this montage #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd(0x27, 16, 2); // Adresse I2C 0x27 (du LCD DIYables), 16 colonnes et 2 lignes int trigPin = A0; // Broche TRIG int echoPin = A1; // Broche ECHO float duration_us, distance_cm; void setup() { lcd.init(); // Initialisation de l'écran LCD lcd.backlight(); // Activation du rétroéclairage pinMode(trigPin, OUTPUT); // Configuration de la broche TRIG en mode sortie pinMode(echoPin, INPUT); // Configuration de la broche ECHO en mode entrée } void loop() { // Génère une impulsion de 10 microsecondes sur la broche TRIG digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); // Mesure la durée de l'impulsion depuis la broche ECHO duration_us = pulseIn(echoPin, HIGH); // Calcule la distance en centimètres distance_cm = 0.017 * duration_us; // Affiche la distance sur l'écran LCD lcd.clear(); lcd.setCursor(0, 0); // Début de l'affichage à la première ligne lcd.print("Distance: "); lcd.print(distance_cm); delay(500); // Attente de 500 ms }
Along with the soldering they will provide the sponge, you need to wet the sponge with the water. While using the soldering some times you need to rub the soldering rod tip to the sponge, then it will clean the tip of the rod. To avoid the tip becoming black. Use HOKI soldering tip very good and long lasting.
There is an important piece of code missing in the program under: pinMode(talkButton, INPUT); should be written: digitalWrite(talkButton, HIGH); This way the floating talkButton will be high or low but not floating in between which is causing it to get from receiving to send thousands of times a second. That is what is causing the noise when receiving because it is partially sending as well. With an added digitalWrite(talkButton, HIGH); both sides are muted when no button is pressed. With the button down the program is clearly in sending mode and not echoing. Please repair this in your program because this is disappointing many enthousiasts in electronics which we need dearly in this world.
