How to use 315Mhz RF transmitter and receiver modules with arduino
Description:Â This wireless transmitter and receiver pair operate at 315Mhz. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair….

Arduino Project 19- Moisture sensor project
This small module helps you measure moisture of soil. It is a low cost sensor that you can purchase from Ebay. To modify the sensitivity of the soil moisture sensor, just rotate the potentiometer on the module.
Telephone misuse indicator
When the phone line is in idle condition (on hook), the full voltage of 48V DC from the exchange appears across the line. When the phone is engaged by lifting the hand set, the voltage across the line falls down to around 12V. Thus, under idle condition (48V), VR1 is adjusted to give a positive biasing voltage to the base of Q3. As Q3 conducts Q1 gets into reverse bias and stops conduction. If the phone is engaged, Q3 stops conducting due to voltage drop across the lines, and subsequently, Q1 and Q2 starts oscillating and beeping is heard. Thus, this circuit can be used as an indicator for telephone tapping and misuse by an unauthorized person.

DIY KIT 13- Jaycar’s Skeet Shooting Game DIY Kit
This is the “Skeet” Shooting Game Project from Jaycar. The kit checks your hand and eye coordination. There are 9 green and 1 red LED. There are two switches: one is reset switch and the other is FIRE switch.
Dark sensor on breadboard
The circuit is ready for testing. Connect battery terminals and see the output. As you block light falling on LDR(Light dependent resistor), the LED glows.
OUTPUT:

THIS CIRCUIT IS EXTREMELY SENSITIVE TO DARKNESS. EXPERIMENT THE CIRCUIT IN A HIGHLY ILLUMINATED ROOM.
LED GLOWS EVEN IN LESS DARKNESS. Use torch light if the LED glows in less darkness. You can adjust the sensitivity of the circuit using a variable resistor in place of R3-300Ohm. Try this circuit with other resistances as well, for example, 1K, 10K and 100K, etc.
