![]() ![]() It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. It also analyzes transistor's characteristics such as voltage and gain. #include SPI.h> // Not actually used but needed to compileĭnd((uint8_t *)msg, strlen(msg)) ĭnd((uint8_t *)SensorCharMsg, strlen(SensorCharMsg)) ĮSR Meter / Capacitance / Inductance / Transistor Tester KitĮSR Meter kit is an amazing multimeter that measures ESR values, capacitance (100pF - 20,000uF), inductance, resistance (0.1 Ohm - 20 MOhm), tests many different types of transistors such as NPN, PNP, FETs, MOSFETs, Thyristors, SCRs, Triacs and many types of diodes. Message with a good checksum received, dump it. If (driver.recv(buf, &buflen)) // Non-blocking #include SPI.h> // Not actualy used but needed to compile You can read more about this project here. The RadioHead library is great and it works with almost all RF modules in the market. Install the RadioHead library in your Arduino IDE Here’s the library you need for this project:ģ. You need the following components to make this circuit: Those messages are being displayed in the serial monitor on the receiver. In this project the transmitter is sending a message “Hello World!” to the receiver via RF. These modules are cheap and you can use them with any microcontroller (MCU). The 433MHz is used on a wide variety of applications that require wireless control. ![]() These RF modules are very popular among the Arduino tinkerers. ![]()
